22.5 = x

Step-by-step explanation:

I'm using Pythagorean theorem.

A^2+B^2=C^2

18^2+13.5^2=C^2

324+ 182.25=C^2

506.25=C^2 ( now square root both sides)

22.5=c

x=22.5 meters

Step-by-step explanation:

I used the pythagorean theorem. (a squared+b squared= c squared. just put x in place of c

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
