1) 15.5 - 6 = 9.5
therefore, the birds new location is 9.6 feet above the ground.
2)2.25 - 1.50 = 0.75
she owes her grandfather $0.75
3) 4.2 - 1.6= 2.6
Steps:
1. Take -x + 2y= 21
2. Add x on both sides
2y= x + 21
3. Divide everything by 2
Y= 1/2x + 10.5
4. Substitute the y in 7x + 2y= -19 for 1/2x + 10.5
7x + 2(1/2x + 10.5)= -19
5. Multiply everything in parentheses
7x + x + 21= -19
8x + 21= -19
6. Subtract 21 on both sides
7. 8x=-40
8. Divide each side be 8
9. Your answer is
X=-5
55 -10 = 452x2 = 47x7 = 494x4 = 1621 + 1 = 2277- 10 = 67x+30=100 = 70 You gave the answers. ???

Answer:
Most everyday situations involving chance and likelihood are examples of simple probability.
Explanation:
The probability is the chance or likelihood of any event happening. In our everyday life, we unintentionally use the probability. For example, we say there is 70% chance that tomorrow will be rain, there is 50% chance that Brazil will win the world cup, there is less likelihood of he arriving today and soon. In all these concepts we are dealing with uncertainty and there is chance factor involved in all these examples. So in most everyday situations which involve chance and likelihood are actually examples of simple probability.
