To do this problem, we must first distribute the 13 and 14 into the parenthesis.
<span>13(9−6m)+14(12m−8)
117 - 78m + 168m - 112
To combine like terms, we can add/subtract terms that have an "m" together and then we can add/subtract terms that do not have "m" together.
117 - 112 = 5
and
168m - 78m = 90m
So our final sum is 5 + 90m</span>

Step-by-step explanation:
What was the answer
32 times 2 is equal to 64
Answer:
2x - 0.4x ;
8x/5 ;
Yes
Step-by-step explanation:
Let number of miles = x
Arlene:
Double number of miles = 2 * x = 2x
Subtract 20% of the result :
2x - 20% of 2x ;
2x - 0.4x
Raul:
Divides Number of miles by 5 ; x / 5
Multiplies result by 8 ;
8 * (x/5) = 8x /5
To know if expressions are equivalent :
Let x = 10 miles
Using Arlene's expression:
2x - 0.4x
x = 10
2(10) - 0.4(10) = 16
Using Raul's expression :
8x / 5
(8*10) / 5
80/5
= 16
Since they give the same result, we can conclude that the expression are equivalent
