Convert 15% to a decimal. When converting percents to decimals, move decimal 2 digits to the left: .15

Find 15% of 1000 gallons: .15 x 1000 gallons = 150 gallons

So the new machine uses 150 gallons less:
Old Machine gallons - 15% of Old Machine gallons = New machine gallons
1000 gallons -150 gallons = 850 gallons

Using the quadratic formula to solve 11x²-4x=1 What are The values of X?

Anvisha [2.4K]

$11x^2 - 4x = 1$
$11x^{2} - 4x - 1 = 1 - 1$
$11x^{2} - 4x - 1 = 0$
$x = \frac{-(-4) \± \sqrt{(-4)^{2} - 4(11)(-1)}}{2(11)}$
$x = \frac{4 \± \sqrt{16 + 44}}{22}$
$x = \frac{4 \± \sqrt{60}}{22}$
$x = \frac{4 \± 2\sqrt{15}}{22}$
$x = \frac{2 \± \sqrt{15}}{11}$
$x = \frac{2 + \sqrt{15}}{11}\ \bold{or}\ x = \frac{2 - \sqrt{15}}{11}$
