Answer: 2 inches, 3 inches, or 3.125 and 2.083
Explanations:
The simplest way is to take 20% of the 2.5 inches and go that much above & below 2.5 inches.
2.5 x 20% = 2.5 x 0.20 = 0.5
So 2.5 - 0.5 = 2 inches was predicted
And 2.5 + 0.5 = 3 inches was predicted.
The more complicated way is to see number + 20% of that number = 2.5, and what number - 20% = 2.5.
Which solution sounds more like what you’re doing in class right now?
If it’s the more complicated way:
0.8x = 2.5 (80% of the predicted rain value equals 2.5)
x = 3.125 inches was predicted
1.2x = 2.5 (120% of the predicted rain value equals 2.5)
x = 2.083 inches was predicted
Sorry, this is probably confusing. Let me know what questions you have.
Answer:
76.1
Step-by-step explanation:
<span>x−27=67 solve for x
Add 27 to both sides, then
x -27 +27 = 67 + 27
x = 94

The ground temperature started at 10 degrees.
The rate was: for every 1000 meters (m) of going above the ground, the temperature dropped 5 degrees, meaning that it got cooler.
The ratio is 1000 meters to 5 degrees
So that would mean: 10-5-5-5-5-5=-15 degrees
