Question

What is 5b-3 if b=7?

Answer 1

Hey there,

To solve we just plug in 7 and get an answer:

• 5(7) - 3
• 35 - 3 = 32

When you plug in 7 for b you get 32 as the answer.

Hope I helped,

Answer 2

Answer: 32

Step-by-step explanation: In this problem, we want to evaluate the expression, 5b - 3, when b = 7.

To do this, we substitute 7 in for b and we have 5(7) - 3.

Now we use our order of operations.

Multiplication comes before subtraction so we first

multiply 5(7) to get 35 then subtract 35 - 3 to get 32.
