Answer:

$x = 4\\y = 9$ hours

Step-by-step explanation:

Given -

x represents the number of hours lifeguarding and y represents the number of hours landscaping

$x+ y = 13$ -----Eq ( 1 )

and

$20 * x + 10 * y = 170$ -----Eq ( 2 )

Substituting the value of $x = 13-y$ in equation 2, we get -

$20* (13 - y) + 10 y = 170$

$260 - 20 y + 10 y = 170\\10y = 90\\y = 9$

$x = 13-9 = 4$

$\frac{2}{3}=\frac{8}{x}$

Cross multiply to solve for x:

2x = 24 so

x = 12

But if it on the other side of 0, it has to be negative. So the ratio is -8/12 which reduces to -2/3.
