There are 792 different ways of choosing 5 books from a shelf containing 12 books. This problem can be solved using the combination formula of mathematics. The combination formula of mathematics is a number of way of selecting thing from a collection and the formula stated as n(n-1)...(n-k+1)/k(k-1)...1 (Calculation: 12*11*10*9*8/5*4*3*2*1 = 95040/120 = 792)<span>.</span>
Answer:
2. 8 * 3 - 10 = 14
3. 9 * 2 - 10 = 0
4. 5 - 15 = -10
5. 0.5 * 40 = 20
Part 3.
1. 0.25x + 30.00= 59.50
You have 118 text messages
2. 21.50x = 129
You can buy 6 pizza pies with your money
Hope these are right!!!!
Rewrite s = 4 + sqrt(s+2) as s-4 = sqrt(s+2)
Square both sides: s^2 - 8s + 16 = s + 2
combine like terms: s^2 - 9s + 14 = 0
Factor this: (s-7)(s-2)=0
Solve for s: s={7, 2}
