This ratio is part:part, meaning that its 3 parts to 2 parts.
12/3=4
2*4=8
12:8 is similar to 3:2
The width is 8.
Yay!
3x+2/x-4=2x+18-7+1/x
3x+2/x-4=2x+1/x+11
3x+2/x+7=2x+1/x
3x+1/x+7=2x
[(3x+1/x+8)/2]/(3x+1/x+7)/2
This simplifies down to
(3x^2+8x+1)/(3x^2+7x+1)
...41
(I checked my work 3 times because if I mess this one up I will never live this down)
Yay?
A pair of children can only sit in these patterns, AC, AE, AF, BD, BF, CA, CD, CE.
There are 6 possibilities for the first seat, 4 for the next, and 2 for the last two. Meaning the possibilities are 6x4x2x2=96
1/3HB=T
1/3B=T/H
B=3T/H
Let x and y be real numbers such that xy=9 Find the set of all possible values of x+y
x times y is 9, meaning that there are 3 possible numbers for both x and y
x=1, 3, 9
y=1, 3, 9
1+9=10
9+1=10
3+3=6
If the roots of the equation 3x^2 - 6x + 5 = 0 are a and b, then find the quadratic whose roots are a + b and 2/(a + b).
x^2-2x+5/3=0
a+b=2
ab=5/3
x^2-(2+1)x+2=0
x^2-3x+2=0
Tens digit, sorry, my mistake
sorry man
3+2+2+4=11
If he eats one per day it will take 11 days to finish.
AAAOOOBBSSSS
One way to do it is as follows
11!/(3!*2!*2!*4!)
Which would be
69300
