Suzy is ten years older than Belly, and the next year she will be twice as old as Billy. How old are they now? Show solution.
Snezhnost [94]

Answer:

I understand there is a typo, so Belly and Billy are the same person. His age is represented as B, and Suzy's as S.

S = 19

B = 9

Step-by-step explanation:

Suzy is ten years older than Belly:

(1)  S = B + 10

the next year she will be twice as old as Billy

(2)  S + 1 = 2 (B + 1)

solving the system of equation (1) and (2):

Making (2) - (1):  

1 = 2 (B + 1) - B - 10 => 1 = 2 B + 2 - B - 10  => 1 = B - 8 => B = 9

replacing in (1) S = 19

Find the greatest common factor of the following monomials 45m 6m^5
zzz [600]
The greatest common factor of 45m and 6m^5 is 3m. Here's how to find a greatest common factor:

1). Figure out the greatest number that divides evenly into every number in a given set. In your case, the number is 3.

2). Figure out the greatest number of variables that each of the monomials share. In your case, both of your monomials have at least 1 m. This can simply be represented as m. 

The final answer is the answers you get from steps 1 and 2 combined.

I hope this helps you out! I have a feeling that my wording might be confusing. If you have any questions, ask me as a comment.
