For this case we have the following solution.
x = gallons of water to be added
For the 10% solution we have:
0.1 * 8 = 0.8
Then, for 5% we have:
(0.8 / x + 8) = 0.05
Rewriting:
(0.8 / x + 8) = (5/100)
Answer:
An equation can be used to find x, the humber of gallons of water he should add is:
(0.8 / x + 8) = (5/100)
Answer:
A number used to multiply a variable. Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient. Variables with no number have a coefficient of 1.

Hope it helps
Answer= 11
Explanation= i plugged it into a calculator
Answer:
I think 138 probably
Step-by-step explanation:
1. I think the distance is 5 miles because the y-axis points for both coordinates are the same, and the difference between the x-axis points is 5; 9-4=5
2.
a. (3, 1) and (3, 5) because if you remove the -, it will be (3, 1) and (3, 5).
b. (-2, -6) , (-2, -10) , (2, 6) , and (2, 10).
b. All you have to do is get 2 points that are negative, and for the other 2 coordinates, remove the negative sign.
Hope this helped☺☺
