So in this case expand the brackets where everything outside the brackets are multiplied into the brackets if that makes sense. Therefore 5 times 3m plus 5 time 2.

(5×3m)+(5×2)
=15m+10

frez [133]

Answer:

Step-by-step explanation:

\frac{Meg}{Tanner} = \frac{4}{3}

Tanner = x    or how far did Tanner drive?

\frac{112}{x} = \frac{4}{3}

\frac{3}{4} * 112 = x

84 =x   so Tanner drove 84 miles  

total driven = 112 + 84

total driven = 196    :)
