10. An athletic field is a rectangle, 120 yd by 60 yd, with a semicircle at each of the ends. A running track 15 yd
wide surrounds the field. How many yards of fencing
do you need to surround the outside edge of the track?
Round your answer to the nearest tenth of a yard. Use
3.14 for T.
60 yd
- 120 yd —

step-by-step explanation:

see if this :

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

could you provide figure.
