40% Because if the shoe is $80 and went on sail to $50 they would have to raise the original price by 20% there for when they say it’s on sail for 30% off it’s really should just be 20% off
Answer:
1. 2+2 = 4
2. 2x +2 = y
3. Terms - 16ab, 5c, 8, 2l, 2w, h, w, l
Coefficients - 16, 5, 8, 2, 2
Constants - 8, h, w, l
4. 2
5. -7
On the left side, distribute the 2 to x and -3 so the left side should look like 5x+2x-6.
on the right, distribute the -2 to x and -1 so the right side should look like -2x+2.
combine like terms on the left to get 7x-6=-2x+2
add -2x from the right side to the left side to make the equation 9x-6=2 now it's a two step equation.
add 6 to 2 to get 9x=8. divide by 9 and x=8/9.
If you want it estimated it would be .55 which would be 55/100 which would simplify to 11/20
