Solve the equation 9r – 2 = 16 for r.
A. 1
B. 2
C. 4
D. 6
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.

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
