15. any number and 0 will have a quotient of 0.
for example 7/0=0 . 8/0=0 . 9/0=0
if you try and check your work using multiplication 7*0=0 . 8*0=0 . 9*0=0
then you will realize the rule is right
Y=-3x+23
distribute -3, get y alone (add 2 to both sides)

Answer:
111°
Step-by-step explanation:
the angle is question is an alternate-interior angle with the one labeled as 111° and alt-int angles are congruent
3,843,000. the number next to 2 (which is in the thousands place) is 5. so we add one and it became 3,843,000
