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
5n + 3 + 4n = 30 combine the like terms on the left
9n + 3 = 30 Subtract 3 from both sides
9n = 30 - 3
9n = 27 Divide by 9
n = 27/9
n = 3

Answer: 2.4 pounds per dollar</h3>
Explanation:
We can set up the ratio
12 pounds : 5 dollars
Then divide both parts of that ratio by 5 so that the "5 dollars" becomes "1 dollar"
The ratio 12 pounds : 5 dollars is equivalent to 2.4 pounds : 1 dollar

slope=y2-y1/x2-x1
y1=4 y2=16
x1=3 x2=5
slope=16-4/5-3
slope=12/2
slope =6
