Answer:
<h2>It'll be an engine with six 500cc cylinders, which give 3.0.</h2>
Step-by-step explanation:
Notice that the number 2.0 describes the numbers of cylinders and their capacity. That is, 4 cylinders with 500cc each, gives a total of 2000, which is equivalent to 2.0 engine.
Having said that, if we add two more 500cc cylinders, the engine would be 3000, which is equivalent to 3.0.
Answer: -2
Step-by-step explanation:
The sum of length and width is half the perimeter, so is (70 in)/2 = 35 in. Since this is the sum of length and width, if we add 5 inches, it will be twice the length. That is ...
... length + width = 35 in
... length + (width + 5 in) = (35 in) + (5 in)
... 2×length = (35 in) + (5 in) = 40 in
The length of the rectangle is 20 inches.
As an expression, this is:
222c - 15 = c
If you want to solve it, add 15 to each side to get:
222c = c + 15
Subtract c from each side:
221c = 15
Divide each side by 221:
c ≈ 0.0678733
