The key words here are <em>less than</em> and <em>3 times</em>. Knee pads are represented by the variable<em> k</em>, and 3 times that price would be 3<em>k</em>. Now, skateboards are $5 less than that price, so the expression that gives the price of a skateboard is 3<em>k</em> - $5.
Answer: B. Every 10th students that enters the cafeteria

B is a random sample, while A, C, and D are biased.
Hey there! :D
All angles in a triangle equal 180 degrees. An exterior angle is supplementary to the interior angle next to it. (also equal to 180 degrees)
92+24+<B= 180
116+<B= 180
Subtract 116 on both sides.
<B= 64
So,
180-64= 116
The exterior angle of <B is equal to 116 degrees.
I hope this helps!
