Your mother has a new cell phone. It comes with 18 applications already installed. She uses only "2" /"3" of those applications. She downloaded an additional 12 applications that she uses regularly. Write an equation to represent the total number of applications your mom uses.

The equation is:  * 18 + 12

She uses 24 applications regularly

Explanation:

We are given that the phone has 18 applications already installed. We are also given that she uses only  of those applications

This mean that she uses  * 18 = 12 applications from the already installed ones

Now, we know that she downloaded additional 12 applications and used them

Therefore, the total number of applications she uses regularly = 12 + 12 = 24 applications

The equation would be obtained by combining the above two steps, it would give us:

number of applications = * 18 + 12

where:

is the fraction used from already installed applications

18 is the number of already installed applications

12 is the number of the additional installed applications

Hope this helps :)

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.
