How many liters are in 21 cups? if 1L=4.2cups
i don't understand how to do it

5 L

Step-by-step explanation:

As given in question,

1 L can fill 4.2 cups.

So, 1 cup can hold L of fluid.

Therefore,

21 cups can hold = × 21

                            = 5 L

So, there is 5 L of fluid in 21 cups.

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
