A
120/55 will give you the time it takes him to get there. If you subtract that value from both sides, you'd have:
120/x = # hours left
From there you could easily solve his average speed home.

Answer:
y=5x+42
subtract 5x from both sides
-5x+y=42
Step-by-step explanation:

-5x+y=42
multiply by -1
5x-y=-42
In standard form, Ax+By=C, the variable A cannot be a negative. However, this is not an option so go with c.
since it's a square all sides are equal so
6.25 multiplied by 6.25
= 39.1 square feet
Well the square root of 49 is 7 so anything with an absolute value over 7 would work and if it is greater than or equal to, than 7 and -7 also work :)
