What value of c makes the sentence 5(c−0.15)=2.50 true?

Answer 1

First, we can simplify the left side of the equation:

5(c-0.15) = 5c - 0.75

Now we can set this equal to 2.50 and solve for c:

5c - 0.75 = 2.50

Add 0.75 to both sides:

5c = 3.25

Divide both sides by 5:

c = 0.65

Therefore, the value of c that makes the sentence 5(c-0.15)=2.50 true is 0.65.
