Each music class sings 8 songs a week. how many songs does each class sing in 5 weeks? 6 weeks? 7 weeks?

step-by-step explanation:

what grade level is this? need to know so i can look in my old textbooks!

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
