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
