Hello!
You solve this algebraically
5x + 2(x - 4) = 5x + x - 10
Distribute the 2
5x + 2x - 8 = 5x + x - 10
combine like terms
7x - 8 = 6x - 10
subtract 6x from both sides
x - 8 = -10
Add 8 to both sides
x = -2
The answer is -2
Hope this helps!
Supplementary angles add up to 180°.
89°= angle 1
x= angle 2
Add the two angles equal to 180°
x + 89= 180
subtract 89 from both sides
x= 91°
ANSWER: The measure of the supplementary angle is 91°.
Hope this helps! :)
Distribute the 5
25t-10=-35
+10 +10
25t =-25
divide by 25 on both sides
t=-1
