Bernard solved the equation 5x+(-4)=6x+4 using algebra tiles. which explains why bernard added 5 negative x-tiles to both sides in the first step of the solution? a) he wanted to create zero pairs on the left side of the equation to get a positive coefficient of x on the right side. b) he wanted to combine more negative tiles with the 4 negative tiles on the left side of the equation. c) he wanted to remove the larger coefficient on the left side of the equation. d) he wanted to have 10 x-tiles on the left side of the equation.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
