${x}^{2} - 4x - 9 = 29 \\ {x}^{2} - 4x - 38 = 0 \\ \\ x12 = \frac{ - b \frac{ + }{ - } \sqrt{d} }{2} \\ d = {b}^{2} - 4ac \\ d = 16 + 152 = 168 \\ \\ x1 = \frac{4 - \sqrt{168} }{2} \\ x2 = \frac{4 + \sqrt{168} }{2}$

Jason has $90 to spend. He wants to purchase a bag for $30, one eraser for $10, and three pencils. Each of the pencils costs the

snow_tiger [21]

90 = 30+10+3x

This equation shows that all the prices of the the bag, eraser, and pencils equals $90. So now all we have to do to find the price of a pencil is solve the equation.

First add the 30 and 10 together.

90 = 40+3x

Then subtract 40 from each side

50 = 3x

Lastly divide each side by 3

x = 16.67

The price per pencil is $16.67

Hope this helps!
