Step-by-step explanation:
only thing you have to do is go to a caculator on your device
7/10x - 5 = 1/2x
7/10x - 1/2x = 5
7/10x - 5/10x = 5
2/10x = 5
x = 5 / (2/10)
x = 5 * 10/2
x = 50/2
x = 25 gallons <===
Answer:
40 in
Step-by-step explanation:
For a width of w, the length is 3w and the area and perimeter are ...
A = LW = (3w)(w) = 3w^2
P = 2(L+W) = 2(3w +w) = 8w
We are given the area, so we can find w to be ...
75 in^2 = 3w^2
25 in^2 = w^2 . . . . . divide by 3
5 in = w . . . . . . . . . square root
Then the perimeter is ...
P = 8w = 8(5 in) = 40 in

Answer:
False. 798.7 divided by 1000 is 0.7987 because 1000 has three zeros, so you move the decimal point three units/numbers to the left
False. 73.09 divided by 100 is 0.7309, you are not multiplying by 100
False. 75.04 divided by 10 is 7.504, you are not multiplying by 10
