Answer:
Step-by-step explanation:
All you have to do is add all of the numbers together. Then, divide it by the amount of numbers there.
So, 27+20+15+31+13+22+31+5=164
And they gave us 8 numbers.
So, divide 164 by 8
Answer: 20.5
69 pages.
276 • 25 = 6900
6900 / 100 = 69
That is your answer.
The equations have the same solution are 2.3p – 6.5p + 0.01p =– 4 + 10.1 and -4.19p = 6.1
<h3>linear equation</h3>
This are equations that has a leading degree of 1. GIven the expression as shown below
2.3p – 10.1 = 6.5p – 4 – 0.01p
Collect the like terms
2.3p – 6.5p + 0.01p =– 4 + 10.1
Simplify
-4.19p = 6.1
Hence the equations have the same solution are 2.3p – 6.5p + 0.01p =– 4 + 10.1 and -4.19p = 6.1

Answer:
2.625 pounds are left or 2 5/8
Step-by-step explanation:
So if your going to be subtracting a fraction from a whole number your going to have to consider the fact that the whole number can be divided up into that fraction.
So in this equation we are subtracting 2 3/8 from 5, we are going to take one from 5 and make it into a fraction so we can subtract:
5 = 4 8/8
Now we subtract 2 3/8 from 4 8/8
4 8/8 - 2 3/8 = 2 5/8
so there's your answer 2 5/8 pounds are left over, but if you wanted the answer in a decimal you would divide 5 by 8:
5/8 = 0.625
you then add 0.625 to 2:
2 + 0.625 = 2.625
And that is also your answer: 2.625 lbs. were left over.
