Answer:
Step-by-step explanation:
The area of the swimming pool will be equal to 
.
We know that the length is 
and the width is 
.
Therefore we can substitute those into the equation:
Then, we expand the brackets using a grid (attached).
After this, we collect like terms to find the final answer:
Our final answer is:
The amount of qts to use for 15 gals is 0.6qts
Proportion and ratio
Ratio are written as quotient of 2 integers
Given that 2 qts for every 50 gal of water, this is written as;
2qts = 50 gals
In order to calculate for 15gal, we will have:
x = 15gals
Take the ratio
2/x = 50/15
50x = 30
x = 3/5
x = 0.6qts
Hence the amount of qts to use for 15 gals is 0.6qts

Answer:
Daniel only
Step-by-step explanation:
If you take 72 inches and convert it into yards you get 2 yards.
(divide the length value by 36. so 72 divided by 36 and you get 2 yards)
Answer:
Step-by-step explanation:
If y= x + 4 then plug it into the other equation where the y is. So 5x + x +4=22. Then solve.
for x for y
5x + x + 4=22 y=x +4
6x+4=22 y=3+4
22-4=18 y=7
6x = 18
18/6=3
x=3 so, x=3 and y=7
