Answer:
Step-by-step explanation:
If y is directly proportional to x, then the formula for that is a linear one:
y = kx, where k is the constant of proportionality. In our situation, if the pressure is directly proportional to the temp, then our formula is
P = kT. We need to find that value of k. Plug in what we have:
6 = k(440) so
k = .01363636 or as an equivalent fraction,
Now that have that value of k, we can use it in the formula again, this time with a different value for T to solve for P.
so
P = 5.181818 or as an equivalent fraction,
