What does m represent in the equation K = 1/2mv^2? (Not a response like "slope", but what does it do in this equation?)

Which mathematical statements are true? 1) if 3 is an odd number, then 3 times 3 is an even number. 2) if 6 is less than 7, then 4 is greater than 7. 3) six is divisible by 3, and 10 is a multiple of 2. 4) the average of the data is greater than the largest value in the data, or it’s less than the largest value in the data. 5) the slope of a linear graph is its rate of change, and the graph’s y-intercept is the initial value. 6) if an equilateral triangle has equal angles, then all its angles will measure 45°.

I’m still confused on how to work the percentages

Collin did the work to see if 10 is a solution to the equation r/4=2.4
