Plz help me with 17 part a and b I will thank u

podryga [215]

Part A

There are 2 cups in a pint, so 2 x 3 = 6
Plus 5 cups,
1 quart is equal to 1/4 of a gallon, and there are 4 cups in a gallon,
and another quart is 4 more cups,
so add all of the cups together:
6 + 5 + 4 + 4 = 19

Kelly is incorrect, because I added all of the cups together and I got 19.

Part B

Since 4 cups fit in a quart, and she has 4 quarts, her quarts only hold 16 cups, which isn't enough, because there are 19 cups.

Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)

You went 160 miles in 20 hours. What is the constant of proportionality that relates the y, the distance in miles to x, the time

Mamont248 [21]

Answer:

X = Y times 8

Step-by-step explanation:

You need to figure out how many miles you can go in an hour.

160/x and 20/1

20x=160

x=8

You can go 8 miles in 1 hour.
