Let 't' represent the time of the walk in minutes.
5.1*t = 220
t = 43.14 min
The person needs to walk at least 43.14 minutes to but at least 220 calories.
We know that angle MKJ is comprised of angle MKL and angle LKJ. That means if we add MKL and LKJ, we should get 80 degrees, which is the measure of angle MKJ.
![MKL + LKJ= MKJ \implies \\ 2x+10+3x-5=80 \implies \\ 5x+5=80 \implies\\ 5x=75 \implies \\ x=15](https://tex.z-dn.net/?f=%20MKL%20%2B%20LKJ%3D%20MKJ%20%5Cimplies%20%5C%5C%202x%2B10%2B3x-5%3D80%20%5Cimplies%20%5C%5C%205x%2B5%3D80%20%5Cimplies%5C%5C%205x%3D75%20%5Cimplies%20%5C%5C%20x%3D15%20)
So, we know that our x is 15. That is not enough to tell whether KL is an angle bisector, because we have to evaluate both MKL and LKJ with x=15, so:
![MKL=2(15)+10 = 40\\ LKJ=3*15-5=40](https://tex.z-dn.net/?f=%20MKL%3D2%2815%29%2B10%20%3D%2040%5C%5C%20LKJ%3D3%2A15-5%3D40%20)
So we see that these two angles are actually bisectors, and the third question best describes this phenomenon.
Answer:
A is the true answer and others are wrong
Your answer is 7.
I subtracted 5 from 12 to find the missing number for KL that is 7.
Therefore, your answer is 7
