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

The expression c 2 b ​ + 3 a , when evaluated with a = 5 , b = 12 , and c = 2 , results in 27. This was calculated by substituting the values into the expression and performing the operations according to the order of operations. The final result shows that 12 + 15 = 27 .
