Answer: Our required linear equation would be 
Step-by-step explanation:
Since we have given that
Number of cups = 150
Cost = $20
Number of cups = 400
Cost = $45
Let x be the number of cups, y be the cost .
We will use "Equation of line using Two point slope":

Hence, our required linear equation would be 
Answer:

Step-by-step explanation:
7x + 24x = 25 x
31 x = 25 x
Subtracting 25x to both sides
31x - 25x = 0
6x = 0
Dividing both sides by 6
=> x = 0
1,296.0 I think this is right, I apologize if it’s wrong.
Answer:
46 boxes
Step-by-step explanation:
1012 / 22 = 46
C: 20 m/s
Explanation:
Distance run: 1000m
Time passed: 50s
Distance divided by time equals speed.
1000m / 50s = 20 m/s
