Answer:
1 gallon of paint will paint 400 ft² of the wall
Unit rate = 400 ft² per gallon
Step-by-step explanation:
From the graph, when 1 gallon of paint was used, (x = 1), an area of 400 ft² of the wall was painted (y = 400).
Unit rate = y/x. That is, the amount of square feet of wall that would be painted using 1 gallon of paint.
Unit rate = 400 ft²/1 gallon = 400 ft²/gallon.
If we take 42/4, or any other of the sets, you will get 10.5, which is k.
10.5 is the amount of miles travelled in 1 hour.
Since we just multiply time and miles to get y, our equation will just be in y=kx format. 10.5 * time is the same as writing 10.5x since x is the hours. y would be miles.
Constant of proportionality: k = 10.5
The equation: y = 10.5x

Answer:
13 all three angles =60 in total they equal 180
14) I believe x = 32.5 Am not sure though.
