Answer:
120 minutes.
Step-by-step explanation: it says before it only has 10 gallons left. Subtract to get 90 gallons before solving. 90/0.75=120. It will take her 120 minutes to have 10 gallons left after draining 90 gallons.
Assuming you mean simplified, 66/100=33/50, which can be achieved by dividing both the numerator and denominator by 2.
Answer:

Step-by-step explanation:
This equation is in slope intercept form (
). This is called slope intercept form for a reason -
is always the slope and
is always the y-intercept.
We can see that the coefficient on the x-term is
and the constant being added to it is 5.
This means 5 is the y-intercept.
Hope this helped!
