The equation of the linear direct variation is

N = 9 · 27 + 2 · 31 - 28
n = 243 + 62 - 28
n = 305 - 28
n = 277
Answer:
he have to travel 12 cm/km
Step-by-step explanation:
lets find x by transposing
3x = 2x + 2 (as M is the midpoint)
3x - 2x = 2
x = 2
now put 2 instead of x
3x + 2x +2 = (distance from friends home to house)
3 (2) + 2 (2) +2
6 + 4 + 2
10 + 2
= 12
