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