b 15 miles per hour
c 30 miles per hour
d 65 miles per hour
====================================================
Explanation:
The equation d = 65t means that the rate is r = 65. So Malcolm's family travels at an average rate of 65 mph. Note this is the slope of the line.
The graph has a slope of 50 because each time we go up 50, we move to the right 1. Ie, slope = rise/run = 50/1 = 50. You could use the slope formula to get the same result.
Since the graph has a slope of 50, this means Theo's family is going at an average speed of 50 mph.
Subtract the two speeds to get 65-50 = 15 mph
C. P = 5x + 4y
D. P = 4x + 5y
Answer:
Option C is correct that is P=5x+4y
Step-by-step explanation:
We have given She has 15 eggs and 16 cups of flour in her pantry. Her pumpkin bread recipe uses 2 eggs and 3 cups of flour. Her coffee cake recipe uses 3 eggs and 4 cups of flour
Let x represents number of loaves of pumpkin bread
And y represents the number of loaves of coffee cake Susan bakes
Since, She plans to sell pumpkin bread loaves for $5 each and coffee cake loaves for $4 each.
Hence, P=5x+4y
Therefore, option C is correct.
