Cayley says that the equation p=1.5q and 2/3p=q both represent the same proportional relationship. Mariah says that can't be true because the constants of proportionality are different. With which student do you agree? Explain. I WILL GIVE BRAINLIEST!!!

Let's rewrite the second equation.

2/3p = q

Multiplying both sides by 3/2 gives us

  3/2 · 2/3p = 3/2p

  p = 3/2p

So the second equation is equivalent to the first equation. That means both equations represent the same proportional relationship. Cayley was correct.

sorry if this didn't help.

Step-by-step explanation:

Multiplying both sides by  gives us

So the second equation is equivalent to the first equation. That means both equations represent the same proportional relationship. Cayley was correct.

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
