We have been given an expression 
. We are asked to factor the given expression by grouping.
First of all, we will make two groups of our expression as:
Now we will factor of greatest common factor from each group.
Now we will factor out common terms 
as:
Therefore, the factorized form of our given expression would be .
Fee for distance = total fee - initial fee = 12.70-2.20 = $10.50
Now, for 1 mile = $1.50
for x miles = 10.50/1.50 = 7
So, tom travel 7 miles.
for
x
y
: To do this we must divide each side of the equation by
2
y
which will give us
x
y
while keeping the equation balance.
The thousandth place is the 3rd digit after the decimal.
So your answer is 93.013
