A=LW
L=5+2W
A=50
50=LW
sub 2W+5 for L
50=(2W+5)W
answer is the 3rd equation
To convert mixed fractions to improper fractions:
a b/c=(ac+b)/c so we have:
43/10+127/30+37/15 now making all terms have a common denominator of 30
(43/10)(3/3)+(127/30)(1/1)+(37/15)(2/2)
129/30+127/30+74/30
(129+127+74)/30
330/30
11 acres
Now
11a(25b/a)=275 bags of fertilizer.
Area of a quarter circle = 1/4 * pi * r^2
= 1/4 * pi * 4^2 = 12.6 m to 3 sig figs.
perimeter = 4 + 4 + 1/4 * 2 pi * 4 = 14.3 to 3 sig figs.
