Find the solutions to 6x^2- 54x = 0

Nina [5.8K]

Answer:

A. x = 9

D. x = 0

Step-by-step explanation:

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$6x^{2} -54x=0$

$a=6\\b=-54\\c=0$

substitute in the formula

$x=\frac{-(-54)(+/-)\sqrt{-54^{2}-4(6)(0)}} {2(6)}$

$x=\frac{54(+/-)54} {12}$

$x=\frac{54(+)54} {12}=9$

$x=\frac{54(-)54} {12}=0$

therefore

The solutions are x=0 and x=9

21r-7-r+5=-52 solve for r

malfutka [58]

Answer:

r = - 2.5

$r=-2\frac{1}{2}$

Step-by-step explanation:

21r - 7 - r + 5 = - 52

20r - 2 = - 52

20r - 2 + 2 = - 52 + 2

20r = - 50

20r ÷ 20 = - 50 ÷ 20

r = - 2.5

grin007 [14]

Answer:

The original price of her purchase was $65.

Step-by-step explanation:

From the information given, you know that $13 represents 20% of the original price and you can use a rule of three to find the value that represents 100%, which would be the original pice of her purchase:

$13 → 20%

x ← 100%

x=(13*100)/20

x=1300/20

x=65

According to this, the answer is that the original price of her purchase was $65.
