Answer:
5
Step-by-step explanation:
6a = (a*-3) + 45
then:
6a = -3a + 45
6a + 3a = 45
9a = 45
a = 45/9
a = 5
Check:
6*5 = (5*-3) + 45
30 = -15 + 45
If 14 of the 50 fish were trout, we can write this as a fraction; 14/50.
To get this into an easier-to-understand form, we can multiply both sides by 2, giving us a fraction of 28/100. This means that 28 out of 100, or 28% of fish, will be trouts, at least for a rough expectation.
From there, we can multiply 28%, the percentage of trout, by 7,500, the total amount of fish in the lake.
7,500 x 28% = 2,100
Therefore, we can roughly expect about 2,100 of the fish in the lake to be trout.
Hope this helps! :)

<h3>
Answer: -14 degrees Fahrenheit</h3>
Explanation:
Draw a vertical number line. At the center is 0. Anything above this marker represents positive temperatures. Anything below 0 is negative. So we'll have -8 below 0. Move 6 spaces down to go from -8 to -14. You can think of it as moving 6 floors down a building to go from basement level 8 to basement level 14.
