Question

Evaluate 6a + 4b - 30when a = 4, b = 7, and c=2

Answer 1

Given the algebraic equation

`6a+4b-3c`

We evaluate this algebraic equation for a = 4, b = 7, and c = 2. We substitute these values on the equation above, we get

`6(4)+4(7)-3(2)`

Let's do the multiplication first before we proceed with addition/subtraction. We have

`24+28-6`

Applying addition and subtraction, we get

`\begin{gathered} 52-6 \\ \rightarrow46 \end{gathered}`

Answer: (c) 46
