cestrela7 [59]

Answer:

(15x-2)°+( 7x+4)°=90° --> 15x-2°+7x+4°=90° --> 22x+2°=90° --> 22x=90°-2° --> 22x=88° --> x=88/22 --> x=4.

m/_BAC=(15x-2)°=15×4-2 =58°

m/_CAD=(7x+4)°=7×4+4= 32°.

How to solve -2(-4f+5)=-7+2f-9

Damm [24]

Answer:

$f=\frac{3}{5}$

Step-by-step explanation:

$-2(4f+5)=-7+2f-9$

First, use PEMDAS to distribute the -2 to the parenthesis.

$-8f -10 = -7+2f -9$

Combine like terms on the right side.

$-8f - 10 = -16+2f$

Now, you may either subtract the f's or the constants. I'll subtract the constants first, meaning I will add 10 to both sides.

$-8f = -6 + 2f$

Now subtract the 2f from both sides.

$-10f = -6$

Divide both sides by 10.

$f = \frac{-6}{-10}$

Simplify.

$f = \frac{3}{5}$
