Answer: x = -10 . _________________________________________________ Explanation: _________________________________________________ x + 42 + x + 65 = 87 ; Solve for "x" ;
2x + 107 = 87 .
Subtract "107" from each side of the equation:
2x + 107 − 107 = 87 <span>− 107 ;
2x = -20 ;
Divide each side of the equation by "2" ; to isolate "x" on one side of the equation; and to solve for "x" ; ____________________________________ 2x / 2 = -20/2 ;
x = -10 . ______________________________________________</span>
The times in seconds it took 6 finalists to run a 100 meter dash are 12.5 12.4 12.4 12.3 12.6 and 12.4. Mr. Brown picks out the time that appears the most to find the <u>mode</u> he arranges the times in increasing order and picks the middle value to find the <u>median</u>
The answer would be B. As you can see Angle A and angle B are connected by that line and together they would equal 90 degrees like on the other side of line AB.
