Answer:
53
Step-by-step explanation:
I assume the question is find the value of 5y+3 when y=10.
5y+3
5*(10)+3
= 50 + 3

Let us take the case of 7 pounds for $8.47 first.
7 pounds of a product costs = 8.47 dollars
Then
1 pound of the same product will cost = (8.47/7) dollars
= 1.21 dollars
Now let us take the case of 9 pounds for $11.07
9 pounds of a product costs = 11.07 dollars
Then
1 pound of the same product will cost = (11.07/9) pounds
= 1.23 dollars
So from the above deductions we can see that 9 pounds for $11.07 is a better buy than 7 pounds for $8.47. I hope the procedure is clear enough for you to understand. In future you can use this method for solving similar problems.
Answer:
amplitude = 5
Step-by-step explanation:
The amplitude is the average of the maximum value subtract the minimum value
maximum value = 6 and minimum value = - 4, hence
amplitude = = = 5
836, because 484 divided by 22 is 22, so each gallon can do 22 miles. 38 times 22 is 836.
