A coin weighs 8/15 ounces. A different coin weighs 4/15 ounces. How much do the two coins weigh together?

12/15 ounces

this is because 8/15 + 4/15 = 12/15

hope this is helpful!

step-by-step explanation:

i could only see the first page. the other pages were blurry. ; -;

x hot dogs for 2$, y drinks for 3$. 29 items and total 70

2x+3y=70

x+y=29

if x=17and y=12

2(17)+3(12)=70

34+36=70
