Answer:
A) 1/13
B) 1/52 (or 1/4)
Step-by-step explanation:
52 cards in total.
4 Queens in total.
4/52=1/13
1 Queen of diamonds.
1/4 of 1/13 = 1/4×1/13 = 1/52
The second part of the question isn't overly clear, so I think that the answer is most likely 1/52, but could be 1/4.

Answer:
- equation: w +(2w -3) = 18/2
- length = 5 cm
- width = 4 cm
Step-by-step explanation:
Let w represent the width in cm. Then the length is 2w-3, 3 cm less than twice the width. The perimeter is twice the sum of these, so the sum of length and width is half the perimeter:
w + (2w -3) = 18/2
3w -3 = 9 . . . . collect terms
3w = 12 . . . . add 3
w = 4 . . . . divide by 3
2w-3 = 2·4 -3 = 5 . . . . length
The equation is w + (2w -3) = 18/2; the length is 5; the width is 4.
