Let the original price = x
then  76.50 = 0.90x
x = 76.50 / 0.90 = 85

This being algebra, your best bet would be to represent the "original price" by a letter, such as n.

If there's a 10% discount on this item, the price you'd pay would be (1-0.10)n, and this price is $76.50

Solve (1-0.10)n = $76.50 for n.

The answer is D.

9/12 = 3/4
16/24 = 2/3

2/3 is not equivalent to 3/4

Find the measure of each angle.
Galina-37 [17]

<u>Given</u>:

Given that the isosceles trapezoid JKLM.

The measure of ∠K is 118°

We need to determine the measure of each angle.

<u>Measure of ∠L:</u>

By the property of isosceles trapezoid, we have;

\angle K+\angle L=180^{\circ}

118^{\circ}+\angle L=180^{\circ}

           \angle L=62^{\circ}

Thus, the measure of ∠L is 62°

<u>Measure of ∠M:</u>

By the property of isosceles trapezoid, we have;

\angle L \cong \angle M

Substituting the value, we get;

62^{\circ}=\angle M

Thus, the measure of ∠M is 62°

<u>Measure of ∠J:</u>

By the property of isosceles trapezoid, we have;

\angle J \cong \angle K

Substituting the value, we get;

\angle J =118^{\circ}

Thus, the measure of ∠J is 118°

Hence, the measures of each angles of the isosceles trapezoid are ∠K = 118°, ∠L = 62°, ∠M = 62° and ∠J = 118°

Please I need like an explanation of how it was done.
a_sh-v [17]

Answer:

  the point is (3, 3) . . . . . . y = 3

Step-by-step explanation:

Write the point-slope equation of the line through the point you know. Then evaluate that equation for x=3 to see what the value of y is.

Point-slope form:

  y = m(x -h) +k . . . . slope m through point (h, k)

  y = -1/2(x -9) +0 . . . . line with slope -1/2 through point (9, 0)

For x=3, the value of y is ...

  y = -1/2(3 -9) + 0 = -1/2(-6) = 3

The value of y is 3.
