25. You need to divide 3240 by 6, and 1100 by 2. Are those equal? That's what it's asking. It would not be equal, because 3,240 miles would be 540 miles per hour and 1100 would be 550 per hour. Very close, however.
26. If 15 scoops makes 5 gallons, then divide 15/5. That's 3 scoops per gallon. It's asking how many gallons can be made with 6 scoops. That would be 2 gallons.
27. All it's asking is 38 times 5, which would be 190.
28. Since 5 gallons goes into 15 gallons three times, you would divide $22.20 by 3. That would be $7.40 each 5 gallons.
Answer: the first on is 7
Step-by-step explanation:
Answer:
Step-by-step explanation:
Let's start by taking a look at the blue line. The slope of any line that passes through two points is equal to the change in y-values over the change in x-values. We can see that the line passes through points (0, 1) and (1, 0). Assign these points to 
and 
(doesn't matter which you assign) and use the slope formula:
Let:
The slope is equal to:
Therefore, the slope of this line is -1. In slope-intercept form 
, 
represents slope, so one of the lines must have a term with 
in it, which eliminates answer choices A and D.
For the second line, do the same thing. The red line clearly passes through (0, -3) and (3, -2). Therefore, let:
Using the slope formula:
Thus, the slope of the line is 1/3 and the other line must have a term with 
in it, eliminating answer choice C and leaving the answer 
*You can find the exact equation of each line by using the slope formula as shown and plugging in any point the line passes through into
