I think maybe A Im not 100% sure tho
X=25 and y=-2 so then y=-40 and x=? you will have to divide and and multiple and the answer will be x=500
First you would distribute the -3
-3x+1+7x=27
Combine like terms
4x+1= 27
Minus 1 on both sides
4x= 26
Divide by 4
X= 6.5
X and Y can almost be any number and long as the statement 'equal to' is true the equation is correct.
Is A & C.
Explanation:
A. Median for sea turtles:
The set is odd, so median is the middle number - 4
The koi set had 10, even number, so the median for the koi is the average of the 2 middle: 4+3=3.5
Turtles > koi
C. The ages of koi are more spread out - 10. The turtles are only 5.
