Lets say that integer is x so its consecutive number is x+1.
x+ 7+4(x+1)=66
x+7+4x+4=66
5x+11=66
5x=55
x=11
next number is 12
Answer:
15.5^2 + 14.0^ = 20.8^2
436.25 = 432.64
it is not a triangle because a+b is not = c
You have to do 45 divided by 2. Hopefully there is not tax!
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.
