Answer:
14 hours
Step-by-step explanation:
7h - 5(3h-8) = -72
7h - 15h + 40 = -72
-8h +40 = -72
-8h = -72 -40
-8h = -112
h = -112/ -8
h = 14
Answer:
x = 3 - 3/10y
Step-by-step explanation:
2/3x + 1/5y = 2
Subtract 1/5y from each side
2/3x + 1/5y -1/5 y= 2-1/5 y
2/3x = 2-1/5y
Multiply by 3/2 to isolate x
3/2 * 2/3x = 3/2 (2-1/5y)
x = 3/2 (2-1/5y)
Distribute the 3/2
x = 3 - 3/10y
(-(-1))^2
(1)^2
1 x 1
=1
