Answer:
124
Step-by-step explanation:
180-56
First we move 6y to the other side. To do this, you subtract 6y on both sides
C
- 6y = 8.5x + 6y -
6yC - 6y = 8.5x
No divide both sides by 8.5 to isolate x
3/4x+5/6=5x-125/3
3/4x+5/6-5/6=5x-125/3-5/6
4/3x=5x-85/2
4/3x-5x=5x-5x-85/2
-17/4x=-85/2
(-4*-17/4x)=(-85/2*-4)
17x=170
x=170/17
x=10
Answer:
7
Step-by-step explanation:
12 x 12 = 144
144 divided by 20 = 7.2 but round it and get 7
