Answer:
4 classes
Step-by-step explanation:
1. Write an equation for the cost for both members and nonmembers, in which x is the number of aerobics classes.
Cost = 3x + 6 for members
Cost = 4x for nonmembers
2. Set the equations to equal each other and solve.
3x + 6 = 4x
-3x -3x
6 = x
3. Check your answer
4*6 = 24
(3*6) + 6 = 24
For 4 aerobics classes, the cost for members and nonmembers is the same.

Answer:
-7
Step-by-step explanation:
8÷(2×2×2)-16÷2=8÷8-8=1-8=-7
So what there asking is what is the numerator after rewriting the fractions
They simply want you to write the equlivalent fractions so that the fractions can be added
<span>1/4+1/6
=3/12+2/12
------>1/4 and 1/6 were multiplied by 3, to give a common denominator of 12
= 5/12
------> With the same denominator the numerators were added</span>
