48.09

Step-by-step explanation:

This is because doras house is seen times the distance of the other guys sorry forgot his name already but his house is 6.87 miles from the school so simply multiply it by 7 and you get 48.09

6.87x7=48.09

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
