Perimeter: 2l+2w=P
Plug in: 2(35)+3(22)=P
Solve: 70+66=136
The total perimeter of his yard is 136 feet.
Half times $7.25: 136/2=68(7.25)=493
The total cost for half his yard is $493 :)
The answer to the question is 4
Line Q's equation would be y=1/2x+3 and line S's equation is Y=1/2x-2. You would compare them. So you would get 1/2x+3=1/2X-2. Subtract 1/2X from both sides and you get 3=-2. So the answer is these lines have no solution.
