(4y-y)x(9+4x+3y)
Subtract the terms 3yx(9+4x+3y).
Add the terms 3yx(4x+3y+9).
Apply the distributive property
3yx4x+3yx3y+3yx9.
Multiply the terms 12xy+3yx3y+3yx9.
Multiply the terms 12xy+9ysq+3yx9.
Solution = 12xy+9ysq+27y..............
(Note I put sq because my phone don’t allow 2 on a y)

Bens teacher ask him to write a three- digit number that uses the digit 3 once and the digit 6 twice. The value of one 6 needs t
nata0808 [166]
We have three numbers to arrange so that 6 is 1/10 of the value of the other six.

Since position tells us whether we're talking about single, tens, hundreds, thousands (e.g. 25 is two times 10 plus five times 1) we know that the two sixes must be next to each other.

This leaves us with two options.
663 or 366.

In each of these cases the second 6 in the number is one tenth of the first 6.

If we look at the only other option: 636 we see that the second 6 is one hundredth of the value of the first 6.

Five bikers join a race. In how many possible ways can they be arranged as
PolarNik [594]

Answer:

60 different possibilities

Step-by-step explanation:

Number of bikers = 5

Positions = first, second and third

First positions = all 5 riders can take the first spot = 5 possibilities

Second spot = position 1 has been filled hence number of possibilities = ( 5 - 1) = 4

Third spot = position 1 and 2 has been filled ; number of possibilities =. (5 - 2). = 3

Number of possible arrangements :

5 * 4 * 3 = 60 different possibilities

90,88,88,87,84,95,90,80,98,and 100
Nitella [24]
In order to find the median the 1st thing I would do is put the number in order
80,84,87,88,88,90,90,95,98,100 
then cross them out Start with left then go the right and so on...
until you get 1 number in the middle left (Since theirs 2 numbers in the middle add them up and divide by two ) 88+90=178   178/2=89
Median = 89 

Now in Order to find the mean add up all the numbers and divide by however many numbers their are 
You should get 900 then divide by 10 because their were 10 numbers 

So Median=89 &  Mean=90
