-12/13, as you make it into an improper fraction so 12×-1+1=13 so the 13 goes over the 12 to get -13/12 than you flip it to get the reciprocal with is -12/13
Answer:
x≥3.5
Step-by-step explanation:
8x ≥-28
x≥-28/8
x≥-3.5
1/4 acre x 100 acres = 25 acres
208.71" = one side of 1 acre squared in feet
2 x 1/4 x 208.17" = 104.355" (2 x 1/4 acre long ends in feet)
200 x 208.71" = 41,742.000" (2 x 100 (acre long sides) x 208.71")
41,846.335" divided by 3 = 13,948.785 yards of fencing required
To solve this you can multiply the second equation by to get
3x+6y =18
Then you can subtract it by the first equation to get
7y= 14
And get y= 2
Then you plug in y to one of the equations to find that x=2
