Carlos had 7¾ cups of cheese. After making 5 pizzas, he now only has 2 cups of cheese. How much cheese did Carlos use?
Musya8 [376]

Answer:

5 3/4 cups of cheese used for the pizza

7 3/4 = 31/4 cups cheese to start

Two cups of cheese remaining.  2 = 8/4 cups

31/4 cups - 8/4 cups = 23/4 cups used for the pizza.

23/4 = 5 3/4 cups of cheese used for the pizza

Find the distance between the two points (-2,-6) and (0,5).
HACTEHA [7]

Answer: OPTION B

Step-by-step explanation:

You can find the distance between two points by using the following formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Given the points  (-2,-6) and (0,5), you can identify that:

x_2=-2\\x_1=0\\\\y_2=-6\\y_1=5

Therefore, substituting values, you get that the distance between those points is:

 d=\sqrt{(-2-0)^2+(-6-5)^2}\\\\d=5\sqrt{5}
