Answer:
2/5 of a mile
Step-by-step explanation:
The easiest approach is to realise that one hour is 3 times longer than
20 minutes. The longer the time, the more they will pave.
2/5 of a mile, in 20 minutes, how much in 60 minutes?(#)
They will pave 3 times more.
2/15 x 3/1 = 6/15 of a mile
6/15 = 2/5 of a mile

First thing, you need to transform this equation to the form of y = ax + b
So you get:
2x + 5y = 8
5y = -2x + 8

In the form of y = ax + b, a is the slope.
In

, you can see "

", and always the number before x is the slope
So, the slope of 2x + 5y = 8 is

Hope this Helps :)
Answer:
cups of flour
Step-by-step explanation:
A muffin recipe, which yields 12 muffins, calls for 2/3 cup of milk for every 1 3/4 cups of flour.
Then this recipe, which yields one muffin, calls for

cup of milk for every

cups of flour.
