Since the workouts are normally on hour scale, thus the first comparison of $9.00 per hour of childcare is more appropriate here.
<h2>Given that:</h2>
- Gym A charges $9.00 per hour of childcare.
- Gym B charges $0.75 per 5 minutes of childcare
<h2>How to find which scale is appropriate when?</h2>
Firstly try to find what is the usual scale used for that work.
The usual scale used for given specified work is mostly the appropriate scale.
For Gym case, people are not coming and going in minutes scale, but they count in hours and will be able to comprehend the hour scale better.
Both Gym although offer same price (since $0.75 per minute is equal to $9.00 per hour), but the cost Gym A specifies is more easy to understand for normal public, thus it is more appropriate scale.

<span> x – 3y = 9 ------------ (1)
1/5x - 2y = -1---------- (2)
(1):
x - 3y = 9
x = 9 + 3y ----------- (1a)
(2):
</span>1/5x - 2y = -1
x - 10y = -5 --------- (2a)
Sub (1a) into (2a):
9 + 3y - 10y = -5
9 - 7y = -5
-7y = -5 - 9
-7y = -14
7y = 14
y = 2 ---------- Sub into (1a)
x = 9 + 3y
x = 9 + 3(2)
x = 9 + 6
x = 15
Ans: x = 15, y = 2
Answer:
D
Step-by-step explanation:
I know the answer is D because I set the equation to be equal to x.
First, I added c to both sides. The equation looked like: 7x=k+c
Then, I divided 7 on both sides, so x would be by itself. The equation looked like x=k+c/7
In conclusion, the answer is D. x=k+c/7
This is a picture of the work. The answer is t=-4
Less than.
4/4 = 8/2 (Not 4/2)
