Step-by-step explanation:
Her brother has 85 * x stickers.
The solution to this system of equations is x = -3 and y = 4.
Answer:
The total number of partitions is 56.
Step-by-step explanation:
Given : Let S = {1, 2, ...,8).
To find : How many partitions of S are there consisting of exactly two blocks, where one of the blocks has 3 elements and the other block has 5 elements?
Solution :
Set S = {1, 2, ...,8)
According to question,
The first partition consists of 3 elements.
Which means 3 elements can be chosen out of 8 in ways.
i.e.
The remaining 5 elements will automatically fall into the second partition.
Therefore, the total number of partitions is 56.
Answer:
95
Step-by-step explanation:
just divided 285 and 3
Let your age be 'X'
Then the age of your brother will be
The age of your sister is 10, but can also be written as an expression (since it is the age of your brother +6)
Now we get the following equation:
Subtract 6 from both sides
Multiply by 3
Hence, the answer on your question (which is your age) is 12.
