Answer: h x 9 = p
If he works a certain amount of hours and earns 9 dollars for each hour he works (h), you would multiply the two and get an answer (p). :)
10-- 10,20,30,40,50,60,70,80,90
15-- 15,30,45,60,75,90,105
here are a few. The LCM would be 30.

Answer: The answer is A) 2x+50
Step-by-step explanation:
We have a lot of missing values in this equation. We do not know how much hector or sam has, so we need to use variables;
The first thing we know is that hector has twice as much money as sam, so we start with x*2, or 2x. Now we know that ted saved 100 more than hector, so we need to add 100 to 2x, which gives us 2x + 100. Then it states that Gina saved 50 less than ted, so we need to take away 50 from the previous 100, and that leaves us wth 2x + 50.
