Acres = 640 * sq miles
acres = 640 * 3.5
acres = 2,240 square miles

**************************************************************
Incidentally, here's how that 640 acres per square mile is derived.
1 acre = 43,560 square feet
1 square mile = 5,280^2 = <span> <span> <span> 27,878,400 </span> </span> </span> square feet
<span> <span> 27,878,400 </span> / 43,560 = 640 acres exactly</span>

Answer:

x \: is \: not \: a \: solution \: in \to \: 5x + 4 < 19. \\

Step-by-step explanation:

\: if \: x = 3 \: then \\  4x-1=2x +5  \: is \: same \: as  \to \:  \\ 4(3) - 1  = 2(3) + 5\\ 12 - 1 = 6 + 5 \\ 11 =11 \to \: \\  \boxed{ x \: is \:a \:  solution \: here}  \\  \\ if \: x = 3 \\ then \to \\ 5x + 4    <   19\: is \: same \:as \to \\ 5(3) + 4 < 19 \\ 15 + 4 < 19 \\ 19 \: is \: equal \: to \: 19 : \\ 19 \:  can \: not \: be \: less \: than \: 19 \\ \boxed{ henc e\: x \: is \: not \: a \: solution \: here}

-5x+y=6<br> -3x+6y=-12<br> Solving systems of equations by substitution
Yakvenalex [24]

if you isolate y in the top equation to get y=5x+6 then you can substiture y for 5x+6 in the bottom equation because thats what y equals

as of now you have -3x+6(5x+6)=-12 but if you use the distrubite property you would get -3x+30x+36=-12

then if you subtract 36 from both sides you would get -3x+30x=-48 then combine like terms to get 27x=-48 then divide both sides by 27 to get x=\frac{-48}{27} or x≈1.8
