Answer:

2 =x

Step-by-step explanation:

2 - 4x = 3x - 12

Add 4x to each side

2 - 4x+4x = 3x+4x - 12

2 = 7x-12

Add 12 to each side

2 +12 = 7x - 12+12

14 = 7x

Divide each side by 7

14/7 = 7x/7

2 =x

Answer:

x = 2

Step-by-step explanation:

Step 1: Write out equation

2 - 4x = 3x - 12

Step 2: Add 4x on both sides

2 - 4x + 4x = 3x + 4x - 12

2 = 7x - 12

Step 3: Add 12 on both sides

2 + 12 = 7x - 12 + 12

14 = 7x

Step 4: Divide both sides by 7

14/7 = 7x/7

2 = x

Step 5: Rewrite

x = 2

HELP! Find the value of the 30th percentile of the following set of data. 129, 113, 200, 100, 105, 132, 100, 176, 146, 152

BlackZzzverrR [31]

Let list the data in ascending order 100, 100, 105, 113, 129, 132, 146, 152, 176, 200

There are ten numbers so the thirtieth percentile would be the .3 * 10

= 3rd number, ordered from smallest to largest.

so the third number, the thirtieth percentile, is 105
