Question

Evaluate each expression for a= 5, b= 12, and c= 2.

Answer 1

2*12/2+3*5
24/2+3*5
12+3*5
12+15
=27

Answer 2

Answer:

2b ÷ c + 3a = 27

Step-by-step explanation:

Given that a= 5, b= 12, and c= 2.

To solve 2b divided by c+ 3a i.e 2b ÷ c + 3a

we will need to substitute a with the value of a which is 5, substitute b with the value of b which is 12 and c with the value of c which is 2.

Therefore we will have:

2b ÷ c + 3a to be

2(12) ÷ 2 + 3(5)

= 24 ÷ 2 + 15

Recall that in order of operations BODMAS, Bracket, of, division, multiplication, addition and subtraction.

Division come in before addition

So,

= 24 ÷ 2 + 15

= 12 + 15

= 27
