Hi. This is is how it goes tep by step.
Cut the rectangle/shape the way you feel more comfortable. However, you don't know so I will recommend you cut it in half from where the 12 is. so now the 12 ft would be broken in to 2. the top section would be 45 ft because 5 times 9 is 45. the bottom would be 98 because 7 time 14 is 98. the total would be 143. for the first one.
1. A table can be a helpful thing to model the rate of change. It can be used by making an x and y column and listing each number underneath it like so:
x y
1 2
2 4
And so on. The rate of change for that table would be every time the x axis goes up 1, the y axis goes up 2.
2. To find the rate of change using a graph, look at the line on the graph. You can make a small triangle that starts on the line and then comes out and re-connects into the line. Like so - (look at attached picture). And as you go, you count how many you go down or up and how many you go left or right.
*Hopefully this was helpful, sorry if t wasn't!

Same question
x+y=30
x is 1/5 of y
x=y/5
subsitute
y/5+y=30
multily both sidse by 5
y+5y=150
add
6y=150
divide both sides by 6
y=25
subsitute
x=y/5
x=25/5
x=5
the numbers are 5 and 25

It is thirty two cups because that’s how many are in 2 gallons
