Jen solved the equation 100-1/2x=92 to determine the number of questions, x , she answered incorrectly on a text

The given equation is ⇒ 100 - (1/2) x = 92

100 - (1/2) x = 92  ⇒ Add (-100) to both sides

-100 + 100 - (1/2) x = 92 - 100

∴ -(1/2) x = -8           ⇒ Multiply both sides by (-2)

∴ -2 * (-1/2) x = -8 x -2

∴ x = 16

So, the value of  x will be equal 16

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
