2/5 j = 3/4 k or k = 8/15 j
k already has LESS money than j giving him any amount of money will not make them equal
The xterior angles sum to 360 degrees
180 -120 + 180 - 125 + 180 - 130 + 180 - 135 + 180 - 140 +
180 - 145 + 180 - 150 + 185 - 155 + 180 - 160 = 360 9 sides
See image below:
1 pool / ( 1/40 + 1/20) = 1/ ( 1/40 + 2/40 ) = 40/3 hours Simplify if you need......
5 - 1/4(5) - 3/10 (5) =
5 - 5/4 - 15/10
100/20 - 25/20 - 30/20 = 45/20 = 2 dollars and 25 cents
pi * d * h + 1 cm * 8.8 cm2 d = 6.6 cm h = 8.8cm
Sister on crowded side let the escolator carry her 40 - 12 = 28 steps
the other sister has to cover those 28 steps PLUS the original 40 steps = 68 steps
7 out of (3+7) is yellow 7/10
Her new mixture will be 5 out of 7 or 5/7 yellow
7/10 ( 4 gal) + y gallons = 5/7 ( 4+y)
28/10
28/10 + y = 20/7 + 5/7 y
196/70 + y = 200/70 + 50/70 y
-4/70 = -20/70 y
y = 4/20 = 1/5 gallon
Take square root of both sides
x-1 = +-2
so x -1 = 2 or x-1 = -2
x = 3 or -1
Sorry....as I noted in my answer above....147 coins originally is incorrect because 147 + 53 = 200 and you have to have MORE THAN 200 coins after adding the 53 .......
