4a = 36
to solve for a, divide both sides by 4 to get a by itself.
<u>4a</u> = <u>36
</u> 4 4
<u>
</u>a = 9
1/2 (6x - 10) + 10 = 5x - 13
(6x/2) - (10/2) + 10 = 5x - 13
3x - 5 + 10 = 5x - 13
3x - 5x = -13 + 5 - 10
-2x = -18
x = -18 / -2
x = 9
D.) x = 9
They are called vertical angles because the definition of vertical is: <span>in a direction, or having an alignment, such that the top is directly above the bottom. The "angles opposite each other when two lines cross" match the definition.</span>
I believe that y is equal to -5.
y=-5
