Answer:
- C. length = 23 cm; width = 7 cm
Step-by-step explanation:
<u>Let the width is x, then the length is:</u>
<u>Perimeter is:</u>
- P = 2(l + w)
- 60 = 2(x + 2x + 9)
- 30 = 3x + 9
- 3x = 21
- x = 7
<u>Dimensions are:</u>
- Width = 7 cm, length = 2*7 + 9 = 23 cm
Correct choice is C

Answer:
395/136
Step-by-step explanation:
(9 7/8)/(3 2/5) = (79/8)/(17/5) = (79/8)(5/17) = 395/136
Since 9 7/8 is larger than 3 2/5, it is an improper fraction.
Answer:
x= 16.5

1.999… is exactly the number 2.
Let <em>x</em> = 1.999… . Then 1000<em>x</em> = 1999.999… . Subtract <em>x</em> from this to eliminate the fractional part, and you get
1000<em>x</em> - <em>x</em> = 1999.999… - 1.999…
1000<em>x</em> - <em>x</em> = 1999 - 1
999<em>x</em> = 1998
<em>x</em> = 1998/999 = 2/1 = 2
So <em>p</em> = 2 and <em>q</em> = 1.
