300% of what number is 75?.

25

Step-by-step explanation:

Find the number by dividing 75 by 3, since 75 is the number tripled.

75/3

= 25

So, 300% of 25 is 75.

25

Step-by-step explanation:

300% * x = 75

300/100 * x = 75

x = 75 * 100/300

x = 25

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
