Answer: it will take 5 months for both gyms to cost the same.
Step-by-step explanation:
Let x represent the number of months for which the total cost of gyms are the same.
Gym A charges a new member fee of $65 and $20 per month. This means that the cost of using gym A for x months would be
20x + 65
Gym B charges a new member fee of $25 and $35 per month but you get a discount of 20% monthly.
20% of 35 is 20/100 × 35 = 7
The monthly charge would be
35 - 7 = 28
This means that the cost of using gym A for x months would be
28x + 25
The number of months that it will take for the cost of both gyms to be the same would be
20x + 65 = 28x + 25
28x - 20x = 65 - 25
8x = 40
x = 40/8 = 5
Answer:
A. {x | x < 8}
Step-by-step explanation:
First, we divide both sides by 3.
3(x - 2)/3 < 18/3
Then simplify.
x - 2 < 6
Lastly, add 2 to both sides.
x - 2 + 2 < 6 + 2
<u>x < 8</u>
Answer:
let w = the width of the rectangle
let w- 9=the length of the rectangle
A= L×W
220=w(w-9)
220=w^-9w
w^-9w-220=0
(w-20)(w+11)=0
w-20=0 or w+11=0
w=20cm or x-11 illogical answer
