Mr. hinckley owns 83 acres of land. he divides the land into eight equal sections to sell to eight buyers. which phrase describes how much land, in acres, each buyer will receive? a. more than 9 and less than 10 b. more than 10 and less than 11 c. more than 11 and less than 12 d. more than 12 and less than 13

B. more than 10 and less than 11

Step-by-step explanation:

Mr. Hinckley owns 83 acres of land. He divides the land into eight equal sections to sell to eight buyers. The number of acres of land that each buyer will receive is:

83 acre/8 buyer = 10.38 acre/buyer

Each buyer will receiver 10.38 acres of land, that is, more than 10 and less than 11 acres.

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

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
