Aturtle is 30 5/6 inches below the surface of a pond. it dives to a depth of 32 1/4 inches. how far did it dive

It would be 32 1/4 - 30 5/6

129/4 - 185/6

387-370 / 12 = 17/12 = 1 5/12

So, he dived for 1 5/12 inches

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

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
