Answer:
Deductive because you would use multiple statements to draw a conclusion
If we are talking about degrees they should equal 180
Let amount invested at 6% be S
Then amount invested at 8% = 16,000 - S
We therefore have: .06(S) + .08(16,000 - S) = 1,140 .06S + 1,280 - .08S = 1,140 .06S - .08S = 1,140 - 1,280 - .02S = - 140 S, or amount invested at 6% = $ 7,000Amount invested at 8% = $16,000 - 7,000, or $ 9,000
Answer:
3x - 1
Step-by-step explanation:
Note that you are adding the parenthesis together. In this case, you can disregard the parenthesis. Combine like terms (terms with the same amount of variables):
2x + 1x - 3 + 2
(2x + 1x) + (-3 + 2)
3x + (-1)
3x - 1
3x - 1 is your answer.

Answer:
7! ways
Step-by-step explanation:
Given that there are seven books in the Harry Potter series. Suppose you want to determine how many ways you can arrange the books on your shelf.
Here order matters since each series will be different. Hence permutation should be used.
The no of ways of arranging seven books is 7P7 = 7! ways
