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
Answer:
9y+1=32y+1+54
collect like terms, a symbol changes once it crosses the equal to sign =
9y-32y=1+54-1
-23y=54
divide both sides by -23
-23y/-23=54/-23
-23 will cancel -23 to give y
y=54/-23
y=-2.4 or 2 whole number 8/23
