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

 do you have a choice that looks something like those?

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40

the answer is b
