What is the answer to this word problem, Samantha is using a 2 liter pitcher to serve lemonade to 10 of her friends. How many times will she need to fill the pitcher in order to serve each friend 400 milliliters of lemonade?

2

Step-by-step explanation:

10 friends each served 400 ml of lemonade consumes 400 x 10 = 4000 ml = 4 l of lemonade in total

Pitcher size is 2 l therefore 4 / 2 = 2 pitchers are required assuming no losses.

Step-by-step explanation:

The pitcher is 2 liters. 400 milliliters=0.4 liter. There are 10 friends so multiply 400 by 10. That's 4000 milliliters which is 4 liters. Therefore you would have to refill it once to be able to server each friend 400 milliliters.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
