The total is $4,680
you would multiply the number of dresses she made by how much she charged for each one like 30*156 which equals 4,680.
120+0.60m<60+0.90m
subtract o.60m from each side
120<60+0.30m
subtract 60 from each side
60<0.30m
divide each side by 0.30
m=200
If you still need help just ask!
Set both of the equations on the inside of the parentheses equal to zero.
2x - 1 = 0
X + 3 = 0
Now solve for x in both equations
X = 1/2
X = -3
