The correct answer is C, 6/7
Average speed=Total Distance Covered\<span>Total time take<span>n
T.D=240+180=420
T.T=2.5+2=4.5
420\4.5=93.3 km\h
answer=D</span></span>
First subtract 8.5 from both sides, then divide the -1.2 to get x by itself
x=1.5
5(m-1)=-2+9m+5
5m-5=-2+9m+5
5m-5=3+9m
5m-9m=3+5
-4m=3+5
-4m=8
m=-2
make the brainliest.

Plug in what we know:

Find the cube root of both sides:
![\sf~a=\sqrt[3]{2744}](https://tex.z-dn.net/?f=%5Csf~a%3D%5Csqrt%5B3%5D%7B2744%7D)
