Answer:its option a
Step-by-step explanation: the distance formula is y sub 1 minus y sub 2
And x sub 1 minus y sub 2
Well standard form is Ax+By=C, so just move the -7x to the front so -7x+47=16
The average will be the third number, because the first and fifth, as well as the second and fourth, will average out to the third.
Well to make this easier convert the 81% into a decimal also which is 0.81 so the answer would be .81 * .163 and that equals 0.132
Hope this helps!!! It's how I found it I hope it's right
