Answer:

128.74

Step-by-step explanation:

.8x = 120.00

.87x = 112.00

This represents an easier way to do the problem if there is 20% off that means you are paying 80% of the original cost. You are paying 87% if it is 13% off.

To find the price at nine-irons divide 112 by .87

20% of 120 is 24

120 - 24 = 96

96 - 8 = 88

13% of 100 is 13

100 - 13 = 87

Answers

Answer:

7

Step-by-step explanation:

in 5 and 6 there are few flaws in their experiment, so there is no way to disprove the information they find. However in 7, the biologist can't prove that having 4 tagged fish out of 50 means there are 1,800 fish in that quarry. Therefore it is inaccurate and biased.

Answer:

Its B. two

Step-by-step explanation:

9·2 =18 and 18-2 =16

Answer:

B. 2

Step-by-step explanation:

[tex]9r-2=16[/tex]

First, add 2 to 2 and 16.

[tex]-2 + 2 = 0[/tex] (cancels itself out)

[tex]16 + 2 = 18.[/tex]

Now we are left with:

[tex]9r = 18[/tex]

Lastly, divide the coefficient from the answer.

[tex]18/9=2[/tex]

Therefore, the value of 'r' is 2.
