Answer:

Step-by-step explanation:

The easiest first step is to remove the brackets. Other things could be done, but they are done just because you can.

4x = 7 + 3*2x - 5*3        Just to show you more, I'll keep going.

4x = 7 + 6x - 15              Combine the minus 15 and 7

4x = 6x + 7 - 15

4x = 6x - 8                     Now add 8 to both sides. It's a toss up of what to do

4x + 8 = 6x - 8 + 8

4x + 8 = 6x                    Subtract 5x from both sides

4x - 4x + 8 = 6x - 4x

8 = 2x                             Divide by 2

x = 4

The steps usually follow this order.

Answer: 13

Step-by-step explanation: Alright with the median you take all the numbers "11, 20, 17, 8, 8, 9, 20, 13, 21" and put them in numerical order. "8, 8, 9, 11, 13, 17, 20, 20, 21" Then the middle one is the median, since there are 9 numbers you take the fifth one. In this case it is 13. (Only knew the first one since I have no idea what they mean by quartiles)

elena-s [515]
First find numbers that the denominator and the numerator can both be divided with. Such as 3, now 6/3=2 and 9/3=3. So basically it is 2/3. 6/9 simplify to 2/3.
