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:

-4

Step-by-step 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
