Step-by-step explanation:
Answer:
Step-by-step explanation:
2x + 4 = 6x - 10
Minus 2x on both sides
4 = 4x - 10
Add 10 on both sides
14 = 4x
Divide by 4 on both sides
14/4 = x
x = 14/4
Simplify fraction
x = 7/2 or x = 3 1/2
Cost per mile = 
= 0.97
Now,
c - cost for gasoline and maintenance and
m - number of miles traveled
Hence, the required expression is c = 0.97m.
1 inch=8 miles
so if you had x miles on the scale then it is 8 times x mils in real ife
so you are trying to find acutal milage and then convert it to other map of 6 miles per inc
distance=1 and1/2 inches
multiply by 8
1 and 1/2 times 8=8+4=12
so the acual distance is 12 miles
then we convert it
6 miles=1 in
divide by 6
1 mile=1/6 inch
12 miles=1/6 inch itmes 12=12/6=2
2 inches
