Question 389666
4x(.25)+x(.10)=2.20


4x(0.25)+x(0.1)=2.2

Multiply 4x by each term inside the parentheses.
x+x(0.1)=2.2

Multiply x by each term inside the parentheses.
x+0.1x=2.2

Since x and 0.1x are like terms, add 0.1x to x to get 1.1x.
1.1x=2.2

Divide each term in the equation by 1.1.
(1.1x)/(1.1)=(2.2)/(1.1)

Cancel the common factor of 1.1.
x=(2.2)/(1.1)

Divide 2.2 by 1.1 to get 2.
x=2

So if x=2
then 4x(quarters)=8 quarters
and x=2 dimes
