*assume the pool is empty at the beginning
a) plug 3.25 into the equation and solve
h(3.25) = 600*3.25 = 1950 gallons
b) after 3.25 hours the total amount of water will be 1950 gallons
-5x - 35 = 0
-5x = 0 + 35
-5x/-5 = 35/-5
X = -7
Step-by-step explanation:
let the numbers x and y
so x + y =13
x - y = 5
add two equations together
2x = 18
divide both side by 2
x = 9
sub in any equation
9 + y =13
y = 4
the numbers are 9 and 4
