Multiply (h+3t= -10) to get 2h+6t=-20.
(<span>2h+6t=-20</span>) - (2h+t=-8) to get 5t=-28
therefore t=-5.6
put t into any equation. i.e (2h-t=-8) = 2h+5.6=-8
therefore 2h = -13.6
h=-6.8
Answer:
x = 162 cards need to be dealt with
Step-by-step explanation:
Given:
- Estimation of likelyhood of next card to be queen, a king, or an ace:
( 64 - 0.2*x ) / ( 208 - x )
Find:
For what values of x is this likelihood greater than 70%?
Solution:
- Use the likely-hood estimation relation and set up the inequality as follows:
( 64 - 0.2*x ) / ( 208 - x ) > 0.7
( 64 - 0.2*x ) > 0.7*( 208 - x )
64 - 0.2*x > 145.6 - 0.7*x
0.5*x > 81.6
x > 163.2
- It would require 162 cards to be dealt with for the probability of next card being queen, a king, or an ace is greater than 70%

The best answer would be
2.4 x 10 ^6
10 to the sixth power multiplied by 2.4
the answer is -35/66
to divide fractions you take the reciprocal of the second fraction (switching the numerator and denominator) and multiply it so the equation turns into
5/6*(-7/11) = -35/66
hope you understand now
