Answer:
729 m^3
Step-by-step explanation:
Volume of cube = a^3
a= 9m
a^3= 9^3
hence volume = 729m^3
For this, all you have to do is create equations where all you have to do is change the x value. The equation for gym A would be 35 + 42x, where x is the number of months he has the membership, and the first number is the initial fee. The equation for gym B would be 65 + 36x, following the same rules. Now all you have to do is set both of these equations equal to each other:
65+36x=35+42x
Solving this equation results in x=5, which means that he has to have the memberships for 5 months for them to be equal. Now just plug that in to one side of the equation to get the amount he has to spend:
65+36(5) = $245
Answer:
Step-by-step explanation:
let x represents amount.
Then x≥625-137
or x≥488
