The first thing we are going to do for this case is define variables.
We have then:
x: number of gallons of water
y: total weight
We then have an equation of the form:

Where,

Substituting values:

We choose an ordered pair:

Substituting values:

Rewriting:
Answer:
y = 8.34x + 30
Answer:
When it crosses y-axis it means that x coordinate must be 0 so let substitute 0 to x, y=5-2*0
So coordinates are [0,5]
Answer:
I'm assuming that it is a right angle triangle.
Step-by-step explanation:
0.3x0.5=0.15
0.15/2=0.075
missing length is 0.075
5.62 would be 5 62/100 then you can simplify the fraction down
62/100 - 31/50
5 31/50
Hope I helped :)
600km??? Because it’s travelling 600km and hour so it’s average is 600km and hour
