Step One

Find AM

Formula

AM = MN - AN

Givens

MN = 67.2

AN = 32

Solution

AM - 67,2 - 32

AM = 35.2

Step Two

Set up a solution

67.2/35.2 = 81.9/x Cross Muliply

67.2 * x = 81.9 * 35.2 Combine the right

67.2 * x = 2882.88 Divide by 67.2

x = 2882.88/67.2

x = 42.9 Answer

Solve the equation below

tresset_1 [31]

Answer:

(-2, 3)

Step-by-step explanation:

Substitute 2x + 7 for y in y = -2x - 1

$2x + 7=-2x-1$

Add 2x to both sides

$2x + 7 + 2x = -2x - 1 + 2x$
$4x + 7 = -1$

Subtract 7 from both sides.

$4x + 7 - 7 = -1 - 7$
$4x = -8$

Divide both sides by 4.

$\frac{4x}{4}= \frac{-8}{4}$
$x = -2$

Substitute -2 for x in y = 2x + 7

$y = 2(-2)+7$

Simplify both sides.

$y = -4 + 7$
$y = 3$

Therefore, the answer is (-2, 3).
