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

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 :)

Step-by-step explanation:

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
