Question

Add 5 and b. Then, multiply by 2. Which of the following expressions matches the statement above? A. 5 + b × 2 B. 5 × (2 + b) C. b + 5 × 2 D. (5 + b) × 2

Answer 1

D. (5+b)x2

Explanation:

You add 5 and b first, which is 5+b

Then, you have to multiply the whole thing, not just 5 or b, so you put 5+b in parenthesis, which then becomes (5+b)x2

Hope this helps!

Answer 2

D

Explanation:

for PEMDAS to work it would have to be D to start with parentheses.
