Answer:
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

Answer:
Assuming π is represented by 3.14, the correct answer is 
.
Step-by-step explanation:
Because the question is asking for the area of the shaded region, you can ignore the non-shaded versions of the diagram. The formula of finding the area of a circle is 
, where r is the radius of the circle. Since the radius of the shaded circle is 
, you can infer that the area of the shaded region would be 
= 
= .
Answer:
$58,544
Step-by-step explanation:
The total yearly cost is 41,194 + 13,038 + 4,598 = 58,830.
After the scholarship, Amanda's yearly cost is 58,830 − 44,194 = 14,636.
After four years, the cost is 14,636 × 4 = 58,544.
8x=24 which is 3 so x = 3
4y=24 which is 6 so y = 6
(3,0) for x and (0,6) for y
