You have a coupon for 10% off the sale price of a surfboard. Which is the better buy? Explain your reasoning.


● 40% off the regular price
● 30% off the regular price and then 10% off the sale price
40% of $150 = ___, so the sale price is ___
30% of $150 = ___, so the sale price is ___
10% of that sale price is ___,so after using the coupon, the sale price is ___

Answer:

t = A - p/pr

Step-by-step explanation:

A = p + prt

A = p(1 + rt)

/p       /p

------------------

A/p = 1 + rt

-1       -1

------------------

A/p - 1 = rt

/r            /r

-------------------

A/pr - 1/r = t

t = A - p/pr

Answer:

t = A - p/pr

Step-by-step explanation:

bring a and the rest of the values to one side

Answer:

A

Step-by-step explanation:

We can solve for H by isolating it on one side of the equation, as follows:

J/H - I/H = G

Taking H as the common denominator:

(J - I)/H = G

Multiplying both sides by H:

J - I = GH

Adding I to both sides:

J = GH + I

Dividing both sides by G:

H = (J - I)/G

So the answer is

(A)

H = (J - I)/G.

Answer:   A

Step-by-step explanation:

\(\frac{J}{H} = G + \frac{I}{H}\)                >Since you are solving for H bring I/H to the other side

                                   by subtracting I/H from both sides

\(\frac{J}{H}- \frac{I}{H} = G\)               >There is a common denominator so you can

                                   combine the fractions

\(\frac{J-I}{H} = G\)                   >Multiply both sides by H or cross multiply whichever

                                  way your mind things about how to get H on top

\(J-I = G(H)\)           >Divide both sides by G

\(\frac{J-I}{G} = H\)                   >Answer is A

ANSWER : HEY MATE

The solution to the equation 2x + 3 = x + 2, where x = -1, is found by isolating the variable "x" and simplifying the equation step by step

Let's create an equation with variables on both sides that has a single solution of "-1."

Let's call the variable "x."

An equation that meets these criteria is:

2x + 3 = x + 2.

We want to isolate the variable "x" on one side of the equation to find the solution.

Start by simplifying both sides of the equation.

On the left side, we have; 2x + 3;

And, on the right side, we have x + 2.

Now solve the equation as;

2x + 3 = x + 2

Subtract x on both sides;

2x - x + 3 = 2

x + 3 = 2

Subtract 3 on both sides;

x = 2 - 3

x = - 1

So, the solution to the equation 2x + 3 = x + 2, where x = -1, is found by isolating the variable "x" and simplifying the equation step by step.

Answer:

There is only one x intercept: x = -0.5 or -1/2

Step-by-step explanation:

To find the x-intercepts of the graph of the function, we need to find the values of x where y = 0. In other words, we need to solve the equation 4x^2 + 4x + 1 = 0 for x.

4x^2 + 4x + 1 = 0

(2x+1)^2 = 0

2x + 1 = 0

2x = 0 -1

x = -1/2

45

Answer is 45

Answer:

45°

Step-by-step explanation:

→ First solve the values within the brackets

45° + 90° = 135°

→ Resubstitute back

180° - 135°

→ Solve

Answer:

C. (2,3)

Step-by-step explanation:

4 to 6 = 2 to 3

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

Answer: I think it's 4.

By multiplying by 4 it would equal -8, which would then cancel out the positive 8 in the equation above. Which would cancel out the y-terms

Answer:

See below;

Step-by-step explanation:

Consider the steps below;

\(1. Measure of Angle 1 - m< 1 + m< 2 = 180, ( Considering They Form A Linear Pair ) m< 1 + ( 145 ) = 180,\\m< 1 = 35 degrees\\\\2. Measure of Angle 2 - m< 2 = m< 4, ( Considering They Are Vertical Angles ),\\m< 2 = 145 degrees\\\\3. Measure of Angle 3 - m< 3 = m< 1, ( Vertical Angles ),\\m< 3 = 35 degrees\\\\4. By Alternate Interior Angles Theorem - m< 5 = m< 3,\\m< 5 = 35 degrees\\\\5. By Vertical Angles Theorem - m< 6 = m< 4,\\m< 6 = 145 degree\\\\\)

\(\\\\\\6. By Corresponding Angles Theorem - m< 7 = m< 3,\\m< 7 = 35 degrees,\\\\7. By Corresponding Angles Theorem - m< 8 = m< 4,\\m< 8 = 145 degrees\)

Thus, we derive such a solution;

m∠ 1 = 35°, m∠ 2 = 145°, m∠ 3 = 35° , m∠ 5 = 35° , m∠ 6 = 145° , m∠ 7 = 35° , m∠ 8 = 145°

Formula used,

Area of rhombus = Base × height

Substituting the values,

\( \longrightarrow\)Area = 18 × 15.5

\( \longrightarrow\) Area = 279 cm²

Therefore, 279 cm² is the area of the rhombus .

Answer:

D) 279 cm²

Step-by-step explanation:

Area of a rhombus formula:
\(A=bh\)

This formula is also used for squares and rectangles.

So, we can substitute in our values such as:

A=(18)(15.5)

simplify

A=279

Now, add our label and units:

A=279 cm²
