Answer 1

Evaluate the expression described below if the number is –3.
Five more than a number tripled.

Solution:

the number tripled is 3(-3) = -9

Five more than the number tripled is: 5 - 9 = -4

Answer 2

-4

Explanation:

Let's write the expression in math language and then we evaluate it if the number is -3.

For us, the "number" will be represented with an x. It says that the number is tripled, so we have 3*x.

But we need five more than that number tripled, so we have 3*x + 5.

Now we evaluate it if the number is -3. For that, we just replace the x with -3:

3*(-3) + 5 = -9 + 5 = -4
