Complete Question
You are organizing books on a shelf. Each book has a width of 3/4 inch. The number of shelves is 12.
Write and solve an inequality for the numbers of books b that can fit on the shelf.
Answer:
a) Inequality for the numbers of books b that can fit on the shelf
= b ≤ 3x/4
b) The numbers of books b that can fit on the shelf is b ≤ 9 books
Step-by-step explanation:
Let the number of books = b
Let us assume the number of shelves= x
Each book has a width of 3/4 inch.
Therefore,
b ≤ 3/4 × x
b ≤ 3x/4
If the number of the shelves is 12
Therefore, the number of books bis
b ≤ 3 × 12/4
b ≤ 9 books
Answer:
n = 9
Step-by-step explanation:
Method 1(Algebra) :
3 + n = 12
3 - 3 + n = 12 - 3
n = 9
Method 2:
3 + n = 12
Move 3 to the other side of the equation.
n = 12 - 3
n = 9
Answer:
1/12
Step-by-step explanation:
The probability of just picking up a 1 is 1/4 since there is only one 1 out of 4 total cards.
If you eliminate that 1 card, there are 3 cards left, and the probability of then picking a 4 becomes 1/3.
Multiplying these probabilities, we get 1/4 * 1/3 = 1/12 as the probability of picking up a 1, not returning it, and then picking a 4 afterward.
