Fifteen times the square of a non-zero number is equal to 20 times number.What is the number? Its not 4/3

e-lub [12.9K]

The number is (2√3) / 3

To find the missing number, convert what it says in words to an equation:
$15 {x}^{2} = 20x$
Divide both sides by 15:
${x}^{2} = \frac{20}{15} \\ \\ {x}^{2} = \frac{4}{3}$
Take the square root:
$x = \sqrt{ \frac{4}{3} } \\ \\ x = \frac{2}{ \sqrt{3} } \\ \\ x = \frac{2 \sqrt{3} }{3}$

I don't understand how to go about solving this equation more specifically the "y". Any help is appreciated. (:

Answer:

y^2/x^6

apply exponent rule:

x^-2/x^4=1/x^4-(-2)=y/y^-1 x^4 -(-2)

then you subtract 4-(-2)=6

y/x^6 y^-1

cancel out the common factor: y^-1 and you get

y^2

x^6
