Evaluate the expression
-c + 7b
when c = -2 and b =5
If c = -2, -c = 2.
Now figure out what 7b would be if b = 5, and add that to -c.
b=5 10+7b
To evaluate the expression -c + 7b, we need to substitute the values of c and b given in the question.
Given c = -2 and b = 5, we can substitute these values into the expression:
-(-2) + 7(5)
First, we simplify the expression within the parentheses by multiplying:
2 + 7(5)
Next, we multiply 7 by 5:
2 + 35
Finally, we add:
37
Therefore, the value of the expression -c + 7b when c = -2 and b = 5 is 37.
