After 45 minutes you will have painted 4*45=180 square feet.
so the total number of painted area, y, is:
y=180+x*(3+4) after the 45 minutes
where x is the number of minutes AFTER THE 45 minutes:
if y is 1000 then
1000=180+x*7
820=x*7
x=117.14
so 117 minutes, or one hour and 57 minutes.
Answer:
x > -2
Step-by-step explanation:
First: - 9x – 15 < 3, you would want to take the 15 and add from each side.
Now it looks like: - 9x < 18
Second: You want to take the -9 and divide it from 18
Now it looks like: x < -2
Third: Chnage the less than sign into a greather than sign because we are dealing with a negative #
Now it looks like: x > -2
You would have to put 4.99 times 20 which will cost 99.80 for 20 gallons.
