Hazel can deliver 20 newspapers in 5 minutes. john can deliver 30 newspapers in 8 minutes. if they worked
together how long would it take them to deliver 930 newspapers?

It takes 2 hours

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

9y = 180
