Question 6 options:
Evaluate.
7(b - 2); b = 8
7(8 - 2) = 7(6) = 42
To evaluate the expression 7(b - 2) when b = 8, follow these steps:
Step 1: Replace b with 8 in the expression.
7(8 - 2)
Step 2: Simplify the expression inside the parentheses.
7(6)
Step 3: Multiply 7 by 6.
42
Therefore, the value of the expression 7(b - 2) when b = 8 is 42.
To evaluate the expression 7(b - 2) when b equals 8, you need to substitute the given value of b into the expression and simplify it.
Step 1: Replace the variable b with its value, 8.
7(8 - 2)
Step 2: Simplify the expression inside the parentheses.
7(6)
Step 3: Multiply the number outside the parentheses by the number inside the parentheses.
42
Therefore, when b is equal to 8, the expression 7(b - 2) evaluates to 42.
