Center of Earth 7. A scientist studies two islands shown at the right. The distance
from the center of the Earth to the equator is about 3960 mi.
a. What is the measure in radians of the central angle that intercepts tl
arc along the equator between the islands? (5pnts)
equator
b. About how far apart are the two islands? (5pnts)
​

what's that

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

positive
