Answer:
The minimum number of miles he should travel is 15 miles
Step-by-step explanation:
Let
x ---> the number of miles traveled
we know that
The number of miles traveled multiplied by $3.71 per mile plus a fixed rate of $10.95 must be less than or equal to the number of miles multiplied by $4.44 per mile
so
The inequality that represent this situation is
solve for x
subtract 3.71x both sides
Divide by 0.73 both sides
Rewrite
therefore
The minimum number of miles he should travel is 15 miles
First group rate is x+10, Second is x
First group made 160, Second made 120
Time the first group will take is 160/x+10, and second is 120/x
Equation is: 160/x+10 + 4 = 120/x
x=10, x=-30
The second group made 10 suits everyday.

Step-by-step explanation:
Actually at first you should plus this tow parameters:2x-3x+10
and then you can put(-2)instead (x).
Now you find answer.
Step-by-step explanation:
(1+3x-1)×{1-(3x-1)}
=3x.(1-3x+1)
=3x.3x
=9x^2.
