Question

What are the answer to this question

Answer 1

Answer: t=-3h+25

Step-by-step explanation:

t=-3h+25

25 degrees is a constant-- it never changes, no matter how many hours goes by. So, you don't multiply a variable with it.

The temperature drops every 3 hours-- this is not constant, since it's dependent on the number of hours that passes. So, use a variable here. Since the temperature drops every three hours, it's -3, and not 3.

Answer 2

Answer:

$t=-3h+25$

Step-by-step explanation:

If we know that when $h=0$, $t=25$, then we can use a direct proportion equation ($x=ky$). The temperature decreases every hour by 3 degrees. However, we know that before any temperature drop, the temperature was 25 degrees. All together, this gives us $t=-3h+25$, where $-3h$ is the temperature drop each hour, and $25$ is the starting temperature. Hope that explained things :)
