# Anumber, n, is added to 15 less than 3 times itself the result is lol, which equation can be used to find the value of n andrwisawesome0
To solve for the system of equations, I will write the equation down as I rewrite the written form.
a number, n, (n) is added to 15 less than 3 times itself (+3n -15). The result is (=) 101. (101)
Now let's write only what's in the parenthesis.
n + 3n -15 = 101. noahtheking67
The equation is 3N-15+N=101 Emanuelle7474
I will write out the equation as the wording goes, then I will only put the equation for better understanding.
A number, n, (n) is added (+)to 15 less than 3 times itself (3n -15). The result is (=) 101 (101).
Now that we have fully explained the situation, let's make our equation.
n + 3n-15 = 101.
I hope this helps, and I hope you can understand this easier as a result! :) heavenwagner

The correct option is;

3·n – 15 + n = 101

Step-by-step explanation:

Here we have,  a question with a word problem

the equation stated is n + (3 × n - 15) = 101

We analyze each of the options to find the correct one as follows;

(a) 3·n – 15 + n = 101

The above equation is equivalent to the equation in the solution above hence it is correct

(b) 3·n + 15 + n = 101

Here 15 is added to 3 times n, therefore it is not correct

(c) 3·n – 15 – n = 101

Here n is subtracted from 3·n - 15 so it is in error

(d) 3·n + 15 – n = 101

Here also n is subtracted while 15 is added so it is not correct. gorillalover9000

see explanation

Step-by-step explanation:

15 less than 3 times n is 3n - 15, thus

n + 3n - 15 = 101 ← equation modelling the situation

4n - 15 = 101 ( add 15 to both sides )

4n = 116 ( divide both sides by 4 )

n = 29 blackwhiteroses383

Option a and  b both are correct.

Step-by-step explanation:

We have been given the information that is: n is added to 15 less than 3 times itself.

The result is 101.

So, the number is 15 less than 3 times to itself means: 3n-15

And n is added to it that means:

n+(3n-15)

And its result is 101 so,

n+(3n-15)=101

After simplification of above expression gives:

4n-15=101.

Therefore, Option a and b both are correct. anuel504

Let the number be 'x'

According to the question,

A number is added to 15 less than 3 times itself.

So,  x + (15 less than 3 times itself)

15 less than 3 times itself = Now,  x + (15 less than 3 times itself) = We get the result as 101.

So,  Therefore, it is the required equation used to evaluate the number 'x'. Smoon1967

A : 3n - 15 + n = 101

Step-by-step explanation:

Solution:-

- We will denote a number as "n".

- The result of 3 times itself less 15 would be:

3*itself - 15

itself = n

3*n - 15

- Then a number "n" is added to the above result:

3*n - 15 + n.

- The result of above expression is 101:

3*n - 15 + n = 101

- Option A is the correct answer dshood6599

4n-15 = 101

Step-by-step explanation:

A number is n, when added to 15 less than 3 times itself result is 101.

As we are given number is = n

Three times itself = 3n

Then, 15 less than 3 times itself = 3n - 15

Now if we add n to 15 less than 3 times itself we get the result is 101. Now the expression will be

n + (3n-15) = 101

4n - 15 = 101 JordanJones04402
1. create an equation --- 101 = n+15+3n
2. simplify (combine like terms) --- 101= 4n+15
3. subtract 15 from both sides (101-15 = 4n+15-15) --- 86=4n
4. divide both sides by 4 (86/4=4n/4) --- 21.5 = n

therefor, n = 21.5

to check the equation just plug in 21.5 for n and it should equal 101  ### Other questions on the subject: Mathematics Mathematics, 21.06.2019, mikey8510
