Answer: 40%
Step-by-step explanation:
The probability of turning over 2 out of 5 letters is 2/5 or 4/10 which is equal 40%
The first thing you need to do, is put the like terms in order. So it would be, (-3x)-2x+7x-15xy+4xy.(basically the 4xy and 2x switch places, just take the sign that's in front of them with them.) Now you would combine the like terms. ((-3x)-2x+7x)-(15xy+4xy). Simplified, the new equation is 2x-19xy.
Hope its right.
1. What you want to do is do is to know 2x is the ratio and x; $140,000 is the 1 brother investment and total is $1,600,000
2. Put them together 2x (140,000 + x + 2x) = 1600,000
3. 280,000 + 2x + 4x = 1600,000
4. 280,000 + 6x = 1600,000
5 1600,000-280,000= 1320,000 /6
6. They each invested $220,000
