I don't care what the area of the whole wall is, because we don't need it to solve this problem. It's just there to confuse us.
==> If he used 3/4 of a gallon to paint 1/5 of the wall, then in order to paint the whole wall, he'll have to use 3/4 of a gallon FIVE TIMES.
(5) x (3/4 gallon) = (15/4 gallon) = <em> 3-3/4 gallons</em>
Solving this problem may be painful, but it's not difficult.
To convert time to a decimal, use a conversion chart to look up the total minutes for the time to be converted. Note down the relevant value.
Answer:
3x²/(3x - 9y)
This should be the simplest form.
Step-by-step explanation:
Combine the fractions:
(5x² - 2x²)/((6x - 6y) - (3y - 3x))
Combine like terms:
3x²/(6x - 3x - 6y - 3y)
Solve.
3x²/(3x - 9y)
Ok
so paid 16
20% off
original-20%=16
that means the shorts were 100-20=80% of the original cost
percent means parts out of 100
80%=80/100=0.80
16=0.8 of ogirinal cost
'of' means mutpliy
16=0.8 times original
divide both sides by 0.8
16/0.8=ogirinal
20==originall
$20=original price
