Question

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

Answer 1

Answer:

x= 66.5

Step-by-step explanation:

1. 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 !
