Can u plz mark me as brainliest? I really need it!
A.
The rate is 12:2
B.
Set up a proportion:
12/2 = x/5
Multiply 5 to both sides:
60/2 = x
Divide:
30 = x
So he will walk 30 miles in 5 hours.
C.
To find out, we can divide 12 / 2.
12 / 2 = 6 miles per hour
4x + y = h
Rearrange the problem so your equation equals x, not h
y - h = -4x
Divide both sides by -4
-4y - 4h = x
Cheers!
