Question

What is A minus 2B plus 3C if a is negative 2, B is three and c is 4.2

Answer 1

Answer: 4.6

Explanation:

We are given the following: "What is A minus 2B plus 3C if a is negative 2, B is three and c is 4.2"

The equation initially looks like:
`A - 2(B)+3C` and after our translation is quickly turned into:
`-2 -2(3)+3(4.2)`

Since this equation has all like terms, it is just a matter of simplification. So our final answer is: 4.6

Answer 2

4.6

Explanation:

a - 2b + 3c

-2 - 2(3) + 3(4.2)

-2 - 6 + 12.6

-8 + 12.6 or 12.6 - 8

= 4.6
