The number of kilograms of water in a person's body varies directly as the person's mass. A person with a mass of 90 kg contains 60 kg of water. How many kllograms of water are in a person whose mass is 75 kg?

50 kilograms

Step-by-step explanation:

The example had a ratio of 90:60, which simplifies down to 3:2 (just like a fraction), and 90 divided by 3/2 is equal to 60

If we apply that ratio to 75, we do the same thing. 75 divided by 3/2, or 75 multiplied by 2/3, or 50. (75/3=25, 25*2=50)

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y
