8+12=20
20+12=32
Just keep adding by 12
Simplifying
8x + 8y = 12
Solving
8x + 8y = 12
Solving for the variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-8y' to each side of the equation. 8x + 8y + -8y = 12 + -8y
Combine like terms: 8y + -8y = 0
8x + 0 = 12 + -8y
8x = 12 + -8y
Divide each side by '8'.
x = 1.5 + -1y
Simplifying x = 1.5 + -1y
First, sort the sumbers in order from the least value to the greatest value.
37, 45, 59, 67, 76, 68, 77, 78, 82, 82, 84, 84, 85, 85, 88, 90, 91, 91, 92, 92, 93, 95, 100, 100
There 24 scores listed. Divide 24 by 2 and you get 12.. Find the 12th number in the ordered list from the least value, which is the number 84. Find the 12th score in the ordered list from the large value, which is 85.
Because there are two central numbers, add the two central numbers and divide it by 2.
84+85=169
169/2=84.5
Take the number of pen per box and multiply by the number of boxes giving you the total number of pens bought
