[(10*30) + (15*35) ] / (10+15)= avg age of all of the members
(1/2, 1/2) ?
Say 'x' is the value before it goes up
it goes up 25 % then it equals 1.25 x
then it goes down to the original value of x
1.25 x - (%1.25 x) = x divide through by x
1.25 - %1.25 = 1
1 - % = 1 / 1.25
% = .2 20 percent
x^3 =x^2 +4x
x(x^2-x-4) = 0
x = 0 , 1/2+ - sqrt(17)/2
Three intercepts
6x^2 -x-2 <0
(3x-2)(2x+1) <0
x = (-1/2,2/3)
3^2 * 3^7 = 39 = (33)3=273
Position of hour hand : 240 degrees + minute /2
Position of minute hand = minute *6
240 + m/2 = minute *6
240 + m/2 = 6m
m= 43.64 = 43.6 min
43.6 minutes after 8 PM
Some chemistry questions are answered here.....what is your question?
-3 added to numerator 2
-3 added to denominator 5
2/5 = .4
(5+x) / (8+x) = 4/10
5+x = (8+x) (4/10)
5 + x = 32/10 + 4/10x
1.8 = -6/10 x
1.8 (-10/6) = x
-18/6 = x
x = -3
13 17 19 = 49 ?
