Question

Evaluate 3 + c − 4 ∙ 3 for c = 5.

Answer 1

Answer: -4

Explanation:

First, let's make sure that our expression is simplified as much as possible.

Given expression:

`\sf{3+c-4\cdot3}`

We can multiply 4 * 3:

`\sf{3+c-12}`

`\sf{c-12+3}`

`\sf{c-9}`

Next, plug in 5 for "c":

`\sf{5-9}`

`\sf{-4}`

Answer 2

Substitute 5 for c so you have the expression

3 + 5 - 4 • 3. Now follow the order of operations

3 + 5 - 12
8-12
-4
