To turn a percent into a decimal, move the decimal point over to the left two places.
For example, 25% would be .25 as a decimal.
An easy way to remember how many places the decimal point moves is by looking at the percent sign. It has two circles on either side of the slash, so two circles = two places.
Plug in the variable for each equation.
For example:
1. -2(11)+7+9(11)-4=88
Answer:
33y+16
Step-by-step explanation:
Break apart the problem:
-4(-4-7y)=16+28y
5y+16+28y=33y+16 (Add like terms)
