Answer:
x=180-68=112
So A and B are not correct.
180-112-27=41
y=41
So, C.
Not exactly sure which equation you meant:
3(100-b)=6b
300-3b=6b
300=9b
b= about 33
100-3b=6b
100=9b
b=about 11
About 6,00 dollars worth of hamburger was sold last month
X+9-3≤14
Add 3 to the other side. (do the inverse of subtraction)
x+9≤17
Subtract 9 on both sides. (the inverse of addition)
x≤8
I hope this helps!
