Answer:

"Mean" means Average and these problems are easy to solve I promise there are ten numbers listed add all of them together 2+1+3+2+2+1+4+0+1+4 That will add up to 20 you divide 20 by ten because there are ten numbers. There are good videos about this on Khan academy for median, mode, and mean which I assume is the unit you're on. :)

31-inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece and the third piece

pychu [463]

"31-inch piece of steel is cut into three pieces"

Call the pieces a,b,c

a + b + c = 31

"second piece is twice as long as the first piece"

b = 2a

"third piece is one inch more than seven times the length of the first piece"

c = 1 + 7a

Ok, we have our equations, let's substitute the second and third into the first.

a + 2a + 1 + 7a = 31

10a + 1 = 31

10a = 30

a = 30/10 = 3

b = 2a = 6

c = 1 + 7a = 22

Check: 3 + 6 + 22 = 31, good

Answer: 3 inches, 6 inches, 22 inches
