A crew has paved 3/4 of a mile of road. If they have completed 50% of the work, how long is the road they are paving?

1 answer:

7 0

1 1/2 miles is indeed your answer because if 50% of the road is done which was 3/4 of a mile just add another 3/4 of a mile if it’s 50% (50% +50%=100%)

Answer:

22x - 14

Step-by-step explanation:

pretty sure its like this..

3(4x-3)+5(2x-1)

= 3×4x + 3×(-3) + 5×2x + 5×(-1)

= 12x + (-9) + 10x + (-5)

and according to the rules of multiplying negative by positive...

= 12x - 9 + 10x - 5

combine like terms using the symbols on its left

= 12x + 10x - 9 - 5

= 22x - 14

You could set up a proportion to figure out the anwer. 15 hurdles/60%=X hurdles/100%. Cross multiply, 1500=60x. Divide by 60, 25=X=total amount of hurdles. Hope this helps!
