PLS i realy need hepl right now help me with this it has 15 points

mean=16.67

median=15

mode=10

Step-by-step explanation:

to find the mean add all the numbers and divide by the number of the numbers I.e

5+10+10+20+25+30=100/6. =16.67

to find the median arrange all the numbers in order either descending or ascending then take the middle number if they are two add the sum and divide by two I.e

5,10,10,20,25,30 middle number(10+20/2)

=15

the mode is the most repeated number which is 10 in the above

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
