The scale on a highway construction drawing is 0.5 inches for every 45 miles. if the drawing shows the highway is 4 inches long, how long is the actual highway?

360 miles

Step-by-step explanation:

Every half inch on the map equal 45 miles on the highway.  Find out how many half-inches there are in 4 inches, and multiply that by 45 to get the answer.  

To do this, first divide 4 by 0.5

  4/0.5 = 4/(1/2)  = 4(2/1)  =  8    

There 8 half-inches in 4 inches

**Also think that there are 2 halves in 1, so in 4 there are 2(4) halves, which is 8

Now take 8 and multiply by 45

8(45) = 360

The highway is 360 miles long

the correct answer is a.) bc< mn 5 stars if this you : )

step-by-step explanation:

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
