T= number of minutes
Multiply 5 liters by number of minutes (t), then add the 17 liters already in the tank. This totals 72 liters or more.
17 + 5t ≥ 72
subtract 17 from both sides
5t ≥ 55
divide both sides by 5
t ≥ 11 minutes
ANSWER: Laura could add water for 11 minutes to be sure the tank has 72 liters or more.
Hope this helps! :)
Let the two numbers be x and y.
Let m = the fraction (or percentage) for increasing the numbers.
Increase x by 5, multiply (x+5) by (1+m), and set it qual to 36.
(x + 5)*(1 + m) = 36
Increase y by 5, multiply (y+5) by (1+m), and set it equal to 36.
(y+5)*(1+m) = 36
Therefore
(x+5)*(1+m) = (y+5)*(1+m)
x + 5 = y + 5
x = y
x - y = 0
Answer: 0.
The difference between the two numbers is zero.
