Evaluate the following expression (7 +5b) + 1 , if b = 3
To evaluate the expression (7 +5b) + 1, we substitute b = 3:
(7 + 5(3)) + 1 = (7 + 15) + 1 = 22 + 1 = 23
To evaluate the expression (7 + 5b) + 1, we are given that b = 3.
Step 1: Substitute the given value of b into the expression:
(7 + 5(3)) + 1
Step 2: Simplify the expression:
(7 + 15) + 1
Step 3: Perform the addition inside the parentheses:
22 + 1
Step 4: Perform the final addition:
23
Therefore, the value of the expression (7 + 5b) + 1, when b = 3, is 23.
