Answer:
(-5,-3)
Step-by-step explanation:
y values minus y values over x values minus x values
So k=katie's' age
m=mara's age
k is 2 times as old as m
k=2m
sum is 24
add means sum
k+m=24
so we have
k+m=24 and
k=2m
subsitute
2m+m=24
add
3m=24
divide both sides by 3
m=8
subsitute again
k=2m
k=2(8)
k=16
katie=16
mara=8
Your answer is A
hope this helped
to get this answer you multiply 475 by 1.75% and then you get 8.31
Answer:
.
Step-by-step explanation:
A point of the form
