S=10
2s - 14
To find the value of 2s - 14, we'll substitute s = 10 into the expression:
2s - 14
2(10) - 14
20 - 14
6
Therefore, when s = 10, the value of 2s - 14 is 6.
Evaluate the expression for c = –3.
Write your answer as a decimal or whole number.
–2 + 5c =
To evaluate the expression –2 + 5c when c = –3, we substitute the value of c into the expression:
–2 + 5c
–2 + 5(-3)
–2 - 15
-17
Therefore, when c = –3, the value of –2 + 5c is -17.
