Use the distributive property to simplify the algebraic expression. (n + t)r

When it says to use distributive property, it means that you are going to "distribute" a variable and/or number to others.
To solve this (n+t)r .... then you would multiply "r" to "n" and then to "t".
It would end up looking like this... nr+tr .
This is your final answer because nothing else can be done to it. :)
I hope I helped you understand.

Answer:

10a and 5a+2a+3a

Step-by-step explanation:

6a + 4a = 10a

10a = 10a

9a is not equal to 10a

10+a is not equal to 10a

5a+2a+3a = 10a

6a - 4a is not equal to 10a

a^10 is not equal to 10a

Hope this helps! :)

What is the multiplicative inverse of the sum of 1/3 + 1/5 ? Express in simplest form

Dima020 [189]

$\frac{8}{15}$

My Work/Reasoning:
First we find the sum of 1/3 and 1/5. $\frac{1}{3} + \frac{1}{5} = \frac{5}{15} + \frac{3}{15} = \frac{8}{15}$
Then, we find the multiplicative inverse, I guess it's also known as the reciprocal. $\frac{8}{15}$ turns into $\frac{15}{8}$
Finally, we simplify. $\frac{15}{8}=1 \frac{7}{8}$
