Omar spends 19 hours in a 2-weeks practicing his tuba skills. How many hours does he practice in 7 weeks

Step-by-step explanation:

I would take 19hours/2weeks=9.5 hours a week than 9.5hours a week times 7 weeks equal 66.5 hours in 7 weeks

Answer 66.5 hours

x = 66.5

Step-by-step explanation:

First you write them down like this:

Hours Weeks

19 - 2

x - 7

2. Then you cross multiply, to make an equation so the equation will be:

2x=19*7

3. Then19*7 is 133 so then the equation gets simplified to:

2x=133

4. Now you divide both sides by 2 because that is how many x's there are. so it will be 133/2=66.5 and the equation is now completed to x = 66.5!
