The answer is 9 because
5x+1+3x+3=20
x=2
3(2)+3
9
for labor. Joni paid $85 less per hour for labor. explanation:
5x - 20 = 8x - 65
-20 = 3x - 65
3x = 45
x = 15
The slope is -3/2
Hope this help!
Step-by-step explanation:
(3,2) is the solution to both equations because if you substitute the the x and y values you get a true statement for example
6(3) + 7(2) =32
18 + 14 = 32
32=32
that is a true statement
you can do the same with system B
8(3) +8(2)=40
24 + 16 = 40
40 =40
which is a true statement
