6(4m-3)=6 what does m stand for?
Answers
Answer:
m=1
Step-by-step explanation:
6(4m-3)=6
24m-18=6
24m=6+18
24m=24
m=24/24
m=1
Hey there!
6(4m - 3) = 6
6(4m) + 6(-3) = 6
24m - 18 = 6
ADD 18 to BOTH SIDES
24m - 18 + 18 = 6 + 18
CANCEL out: -18 + 18 because that gives you 0
KEEP: 6 + 18 because it gives you the value of m
6 + 18 = 24
NEW EQUATION: 24m = 24
DIVIDE 24 to BOTH SIDES
24m/24 = 24/24
CANCEL out: 24/24 (on the LEFT SIDE) because it gives you 1
KEEP: 24/24 (on the RIGHT SIDE) because it gives you the m-value
m = 24/24 or 24/24 = m
SIMPLIFY ABOVE AND YOU HAVE YOUR ANSWER TO YOUR M-VALUE
m = 1
Therefore, your answer is: m = 1

. How many red tiles are in the box? There are red and blue files in a box . The ratio of red to blue tiles is 3 : 5 . There are 12 more blue tiles than red tiles in the box . How many red tiles are in the box ?
Answers
The first piece of information we are given is that the ratio of red to blue tiles is 3:5. This can be written as:
R/B = 3/5
The second piece of information we are given is that there are 12 more blue tiles than red tiles in the box. This can be written as:
B = R + 12
We can solve this system of equations by substituting the second equation into the first equation and solving for R.
Substituting B = R + 12 into the first equation, we get:
R/R + 12 = 3/5
We can then simplify this equation to get:
R = 15
Thus, there are 15 red tiles in the box.

The answer to your question is given below.
Step-by-step explanation:
To know the correct answer to the question, do the following:
√12 + √108
= 12^½ + 108^½
= 4^½ • 3^½ + 36^½ • 3^½
Factorise
3^½ (4^½ + 36^½)
Recall:
4^½ = √4 = 2
36^½ = √36 = 6
Therefore,
3^½ (4^½ + 36^½) = 3^½ (2 + 6)

Hi, I just need help with Letter W problem (ii). I having a hard time finding out the length of line segment CE. Can please help me and show what equation I would use.
Answers
Answer:
Step-by-step explanation:
Problem W, Part (i)
The order of the letters is very important when it comes to figuring out similarity statements. This is because the angles must match up. Recall that similar triangles have corresponding angles that are congruent.
The diagram shows that
A = 60 and E = 60
Since A is listed first in ABC, this means E must be listed first in the answer.
Then we'll have D listed next because B = 55 and D = 55 are congruent angles.
The last remaining letter is C. Therefore, the correct sequence is EDC
Answer: EDC===========================================================
Problem W, Part (ii)
Like with the previous part, the order is important. Not only to help match up corresponding angles, but also to pair up the corresponding sides as well.
AB = 12 mentions the first two letters of ABCED = 16 mentions the first two letters of EDCboth of those mention the first two letters of their triangle name.
This then leads to AB/ED being one ratio we can form.
-------------
AC = 10 mentions the first and last letters of ABC
EC = x mentions the first and last letters of EDC. Note that EC is the same as CE.
So we can form AC/EC as another ratio. The key here is that this ratio is equal to the other ratio AB/ED we formed earlier (or else the triangles wouldn't be similar)
---------------
The takeaway from those last two sections is that we can form this proportion
AB/ED = AC/EC
Apply substitution and solve for x
AB/ED = AC/EC
12/16 = 10/x
12x = 16*10 ... cross multiplication
12x = 160
x = 160/12
x = 40/3
x = 13.333 approximately
Answer in fraction form = 40/3Answer in decimal form = 13.333===========================================================
Problem W, Part (iii)
This part isn't too lengthy compared to part (ii). All we simply do here is divide any side of triangle EDC by its corresponding side of triangle ABC.
The easiest in my opinion is to pick on sides that are already mentioned in the diagram, so we could say:
scale factor = ED/AB = 16/12 = 4/3 = 1.33 which is approximate.
The scale factor indicates that triangle EDC has its side lengths roughly 1.33 times larger compared to the corresponding side lengths of triangle ABC.
Any time the scale factor is larger than 1, it means the image is going to be larger compared to its preimage. If the scale factor was between 0 and 1, excluding both endpoints, then the image would be smaller than its preimage.

The rear windshield wiper of a car rotated 120 degrees,as shown. Find the area cleared by the wiper. 25inch,120 degrees, 14inch
Answers
The rear windshield wiper of a car rotated 120 degrees, as shown in the figure. The area cleared by the wiper blade is approximately 205.875 square inches.
The problem states that a car’s rear windshield wiper rotates 120 degrees, as shown in the figure. Our aim is to find the area cleared by the wiper.
The wiper's arm is represented by a line segment and has a length of 14 inches.
The wiper's blade is perpendicular to the arm and has a length of 25 inches.
Angular degree measure indicates how far around a central point an object has traveled, relative to a complete circle. A full circle is 360 degrees, and 120 degrees is a third of that.
As a result, the area cleared by the wiper blade is the sector of a circle with radius 25 inches and central angle 120 degrees.
The formula for calculating the area of a sector of a circle is: A = (θ/360)πr², where A is the area of the sector, θ is the central angle of the sector, π is the mathematical constant pi (3.14), and r is the radius of the circle.
In this situation, the sector's central angle θ is 120 degrees, the radius r is 25 inches, and π is a constant of 3.14.A = (120/360) x 3.14 x 25²= 0.33 x 3.14 x 625= 205.875 square inches, rounded to the nearest thousandth.
Therefore, the area cleared by the wiper blade is approximately 205.875 square inches.

Algebra I
TermsStep-by-step explanation:
Step 1: Define Equation
10x - 6 + 2x = 4(3x - 1) - 2
Step 2: Solve for x
Combine like terms: 12x - 6 = 4(3x - 1) - 2Distribute 4: 12x - 6 = 12x - 4 - 2Combine like terms: 12x - 6 = 12x - 6Add 6 on both sides: 12x = 12xDivide 12 on both sides; x = xHere we see that x does indeed equal x.
∴ any value x would work as a solution to the equation, hence we have infinite amount of solutions.
Answer:
The answer is infinite.
Step-by-step explanation:
So if you first simplify the problem you would have:
12x - 6 = 4 ( 3x - 1 ) - 2
I just combined like terms.
Then you distribute the 4 to the 3x and the negative 1.
So you would have 12x - 6 = 12x - 4 - 2
So once again you would combine like terms and get 12x - 6 = 12x - 6
If you simplified it out and subtracted like terms from both sides you would get 0 = 0 which is true so there is infinite solutions.
you have 51 coins in your pocket, all dimes and quarters. You have $10.20. How many dimes and quarters do you have?
Answers
To find the number of dimes and quarters, you have 17 dimes and 34 quarters in your pocket , when there are 51 coins in your pocket.
To solve this problem, we can set up a system of equations using the given information. Let's use "d" to represent the number of dimes and "q" to represent the number of quarters.
We know that there are 51 coins in total, so we can write the equation: d + q = 51.
We also know that the total value of the coins is $10.20, which can be expressed as 10d + 25q (since dimes are worth 10 cents and quarters are worth 25 cents). So our second equation is: 10d + 25q = 1020.
To solve this system of equations, we can use substitution or elimination. Let's use substitution:
Rearrange the first equation to solve for d: d = 51 - q.
Substitute this expression for d in the second equation: 10(51 - q) + 25q = 1020.
Simplify and solve for q: 510 - 10q + 25q = 1020.
Combine like terms: 15q = 510.
Divide both sides by 15: q = 34.
Now substitute this value back into the first equation to solve for d: d + 34 = 51.
Subtract 34 from both sides: d = 17.
Therefore, you have 17 dimes and 34 quarters.

The answer is TrueIn Triangle XYZ, XZ = XY and m∠Y=57°. The longest side of the triangle is ______.
YZ
XZ
XY
Both XZ and XY
Answers
Answer:
I think YZ 'cause the triangle is iscoceles triangle. As the two sides XY and XZ are equal the longest side is YZ.
since XY=XZ, XYZ is the isosceles and naturally angle Y = angle Z = 57 degree.
so in a traingle the longest side is on the opposite side of the biggest angle.
If the congruent sides measures 57, the angle opposite the base( angle X) would mean 180-57-57 = 66. So basically the side which is opposite to X is the longest and that side being YZ.

URGENT: Given the following information about an ellipse, write its equation: Foci: (3, 1), (3, 5) Endpoints of minor axis: (7, −2), (–1, −2)
Answers
The equation of the ellipse is \((x - 3)^2 / 16 + (y - 3)^2 / 64 = 1.\)
To determine the equation of the ellipse, we need to find its major and minor axes, as well as the distance from each focus to the center.
Given that the foci of the ellipse are located at (3, 1) and (3, 5), we can determine that the center of the ellipse is at the midpoint between these two foci, which is (3, 3).
The endpoints of the minor axis are (7, -2) and (-1, -2), which tells us that the length of the minor axis is 7 - (-1) = 8 units.
Now, let's calculate the distance from the center to one of the foci. Using the distance formula, we have:
sqrt((3 - 3)^2 + (3 - 1)^2) = sqrt(0 + 4) = 2.
Since the foci are vertically aligned, the major axis is vertical. Therefore, the length of the major axis is twice the distance from the center to one of the foci, which gives us 2 \(\times\) 2 = 4 units.
Using the standard form of the equation for an ellipse centered at (h, k), with a horizontal major axis of length 2a and a vertical minor axis of length 2b, the equation is:
\((x - 3)^2 / 4^2 + (y - 3)^2 / 8^2 = 1.\)
