Solve one of the equations below. you must show your work. tell whether it has one solution, an infinite number of solutions, or no solutions. (a) 6x + 4x - 6 = 24 + 9x (b) 25 - 4x = 15 - 3x + 10 - x (c) 4x + 8 = 2x + 7 + 2x - 20

A. 6x + 4x - 6 = 24 + 9x

 10x -6 = 24 + 9x

       +6   +6

10x = 30 + 9x

-9x            -9x

1x = 30 this has an infinite number of solutions.

the perimeter of the field is the sum of the lengths of the four sides:

47 yd + 158 yd + 47 yd + 158 yd = 410 yd

the cost of 3 ft (1 yd) of fence is 3×$3.28 = $9.84.

so the cost of jake's wood perimeter fance is

(410 yd) × ($9.84 /yd) = $4034.40
