Megan has 25 phone numbers stored in her cell phone. abby has some phone numbers stored in her cell phone. together they have a total of 61 phone numbers stored.
if n= the number of phone numbers abby has stored in her cell phone, which mathematical sentamce expresses the information above?

The number of phone numbers Abby has stored in her cell phone, n = 61 - 25 = 36

Step-by-step explanation:

Megan has 25 phone numbers stored in her cell phone. Abby has some phone numbers stored in her cell phone.Together they have a total of 61 phone numbers stored.

Given that n= the number of phone numbers Abby has stored in her cell phone.

We have combined contacts = 61

                25 + n = 61

                   n = 61 - 25 = 36

The number of phone numbers Abby has stored in her cell phone, n = 61 - 25 = 36

total = 61

M ( for Megan) = 25

n = Abby

25+n = 61 or 61-25 = n

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
