The equation which relates the mass and length according to the task content is; l = (3/10)m.
<h3>What is the equation of proportionality?</h3>
From the task content, it follows that the proportional relationship is direct. Hence, the constant of proportionality k can be evaluated as follows;
l = k × m
Hence, k = l/m = 9/30 = 3/10.
Therefore, the proportional relationship is given by the equation; l = (3/10)m

I prefer D.
It's clear that Kevin took (1/4)x.
Keith took (1/4)x -> kevin's amount
* 2 -> twice.
-1 -> 1 less.
So Kevin + Keith = (1/4)x + (1/4)x * 2 - 1 = (3/4)x - 1.
It can either reduce or add to its value. Say that you had a number 5. If you move the place it would make it .5 which reduced its value to not even 1. But with the same 5. if you move the place the other way to 50. It increases its value significantly.
The sum<span> of x, x+2, and x+4 is equal to </span>72<span>.</span>
you would have to do out the equation of 117 divided by 6.5 which would give you 18 feet per second
