Answer: it will take about 5 months for the cost to be the same
Step-by-step explanation:
Let x represent the number of months it will take for the gym memberships to cost the same amount.
A gym membership at A costs $10/month plus a one-time membership fee of $15. This means that the total cost for x months would be
10x + 15
At B, the memberships costs $4/month plus a one-time $40 fee. This means that the total cost for x months would be
4x + 40
For the costs to be the same,
10x + 15 = 4x + 40
10x - 4x = 40 - 15
6x = 25
x = 25/6 = 4.2
Answer:
25.6
Step-by-step explanation:
Add 6.4 to all the sides and add them all together-

Answer:
3ab^2
Step-by-step explanation:
Factor 6a^2b^3
= 2 * 3 * a * a * b * b * b
Factor 15ab^5
= 3 * 5 * a * b * b * b * b * b
Factor 9a^3b^2
3 * 3 * a * a * a * b * b
Common Factor
= 3 * a * b * b
Simplify
= 3ab^2
