Answer:
about 130 hp
Step-by-step explanation:
The displacement is smaller by a factor of 220/390, so we expect the horsepower to be smaller than 230 hp by the same factor:
(220/390)(230 hp) ≈ 129.74 hp ≈ 130 hp
1st: Expand the bracket
3t-3=9+t
2nd: Add the 3 to get rid of it on the first side. Do this to both sides
3t=12+t
3rd: Take away the t on the left hand side and one on the right hand side to just be left with t's on one side and integers on the other side
2t=12
4th: Divide both sides by 2 to find 1t
t=6
