Center A : 375 per yr

Center B : 35 + 12(12) + 5(52) = 35 + 144 + 260 = 439 per yr
I multiplied 12 * 12 because it was $ 12 a month and there are 12 months in a yr. I multiplied 5 * 52 because each aerobic class is $ 5 per class, and she went once per week, and there are 52 weeks in a yr.

so the cheaper one is Center A

A Square was altered so that one side is increased by 9 inches in the other side is decreased by 2 inches.The area of the result
LekaFEV [45]

Let s represent the length of any one side of the original square.  The longer side of the resulting rectangle is s + 9 and the shorter side s - 2.

The area of this rectangle is (s+9)(s-2) = 60 in^2.

This is a quadratic equation and can be solved using various methods.  Let's rewrite this equation in standard form:  s^2 + 7s - 18 = 60, or:

s^2 + 7s - 78 = 0.  This factors as follows:  (s+13)(s-6)=0, so that s = -13 and s= 6.  Discard s = -13, since the side length cannot be negative.  Then s = 6, and the area of the original square was 36 in^2.

Divide 3 over 4 ÷ 1 over 8 = ____.
hammer [34]
When you divide two fractions, you actually just flip one over (it's reciprocal) and multiply them.

\frac{3}{4} ÷ \frac{1}{8}   Use the recriprocal of \frac{1}{8} 
<span>\frac{3}{4} ÷ \frac{8}{1}   Multiply (3 x 8) and (4 x 1)
</span>
\frac{24}{4}       Divide

6


<span>\frac{3}{4} ÷ \frac{1}{8} = 6</span>
