Answer:
x = 30 2/3
Step-by-step explanation:
Angles 4 and 5 are complementary, so we have ...
m∠4 +m∠5 = 90°
(2x +4) +(x -6) = 90
3x -2 = 90 . . . . . . . . . collect terms
3x = 92 . . . . . . . . . . add 2; next, divide by 3
x = 92/3 = 30 2/3
The property shown there is the distributive property.
It states that a(b + c) = ab + ac
Or a(b - c) = ab - ac
Answer:
<h2>5x - 4</h2>
Step-by-step explanation:
= 8x - 4 - 3x = 8x - 3x - 4
= 5x - 4
Answer:
x = 2
Step-by-step explanation:
-5x + 8 = -2
-5x + 8 - 8 = -2 -8
-5x = -10
-5x/5 = -10/5
-x = -2
x=2
