Your answer is 2/1. 2 donuts every minute.
Step-by-step explanation: The rate you are given is 30 donuts every 30 minutes. This equals 30/15.
To make a unit rate, you must make the fraction have a ratio of x/1. You can simply do this by dividing and/or simplifying the equation 30/15.
7. Easiest method is substitution. Since y=x/2, then:
2x+3(x/2)=28
8.Substituting again, we get:
3x-6x=6
-3x=6
x=-2
(-2,6)

Area = 1/2 x base x height
Base = area x 2 / height
Base = 6 1/4 x 2 = 12 1/2 / 3 1/3
Base = 3 3/4 m
I think the answer is c. hope that helps
