Answer:

$\frac{x}{y}$ = $\frac{5}{3}$

Step-by-step explanation:

given 5y = 3x ( divide both sides by 3 )

$\frac{5}{3}$ y = x ( divide both sides by y )

$\frac{5}{3}$ = $\frac{x}{y}$

Answer:

The ratio is 5/3 for x/y

Step-by-step explanation:

We want to find the ratio of x to y or x/y

5y = 3x

Divide each side by y

5y/y = 3x/y

5 = 3x/y

5/3= x/y

The ratio is 5/3 for x/y

Answer:

$\large\boxed{x=3-\sqrt{14}\ \vee\ x=3+\sqrt{14}}$

Step-by-step explanation:

$x^2-6x-5=0\qquad\text{add 5 to both sides}\\\\x^2-6x=5\\\\x^2-2(x)(3)=5\qquad\text{add}\ 3^2\ \text{to both sides}\\\\x^2-2(x)(3)+3^2=5+3^2\qquad\text{use}\ (a-b)^2=a^2-2ab+b^2\\\\(x-3)^2=5+9\\\\(x-3)^2=14\to x-3=\pm\sqrt{14}\qquad\text{add 3 to both sides}\\\\x=3-\sqrt{14}\ \vee\ x=3+\sqrt{14}$
