a number, n, is added to 15 less than 3 times itself. the result is 101. which equation can be used to find the value of n? 3n - 15 + n = 101 3n + 15 + n = 101 3n - 15 - n = 101 3n + 15 - n = 101

a number, n, is added to 15 less than 3 times itself. the result is 101. which equation can be used to find the value of n? 3n - 15 + n = 101 3n + 15 + n = 101 3n - 15 - n = 101 3n + 15 - n = 101

Answer

Explanation:

Step1: Translate "15 less than 3 times itself"

3 times the number $n$ is $3n$, and 15 less than it is $3n - 15$.

Step2: Translate "A number, $n$, is added to 15 less than 3 times itself"

We add $n$ to $3n - 15$, getting $3n-15 + n$.

Step3: Set up the equation

The result of the addition is 101, so the equation is $3n - 15 + n=101$.

Answer:

A. $3n - 15 + n = 101$
