Answer:
x = 17.2
Step-by-step explanation:
since they are supplementary, when you add then together they equal 180
4x + 8 + 6x = 180
Combine like terms
10x + 8 = 180
subtract 8 from both sides
10x = 172
divide each side by 10
x = 17.2

Volume of a cylinder= π r^2 h
.4= radius
π• 4^2 • 3= 150. 79
Five less than a number n
Part A: W = 10x
Part B: S = 400 + 15y
Part C: 490 = 400 +15y
-400 -400
90 = 15y
6 = y, so he worked a total of 46 hours.
Answer:
Step-by-step explanation: your goal is to keep x on one side and everything else on the other.
subtract 1 from both sides
4x = -48
divide 4 on both sides
x= -12
