Answer: B
Step-by-step explanation:
2/3x-1/5=x-1
Add similar elements 23x-15=8x
Subtract x from both sides 8x-x=x-1-x
Simply 7x=-x
Divide both sides by 7 7x = -1
__ __. *Simply: x=-1/7
7 7
X+(-27)=110
x-27=110
x=137
hope that help you

Answer:
Step-by-step explanation:
A) If the playing times are to be the same, then the two expressions for playing time will be equal to each other.
Ron = Sam
3 +1.25c = 8 +0.75c
0.50c +3 = 8 . . . . . . . . . . subtract 0.75c from both sides
0.50c = 5 . . . . . . . . . . . subtract 3 from both sides
c = 5/0.50 = 10 . . . . . divide by the coefficient of c
Each would have to complete 10 chores for their playing times to be the same.
__
B) When c = 4, we have ...
Ron: 3 +1.25·4 = 3 +5 = 8
Sam: 8 +0.75·4 = 8 +3 = 11
Sam spent the most gaming time if both completed 4 chores.
