Answer:
12 and 93.
Step-by-step explanation:
Let the grandsons age be x then Mr. Roger's age = 8x - 3.
Five years ago the grandson's age was x-5 and Mr Rogers was 8x - 8 years old , so:
8x - 8 - (x - 5) = 81
8x - 8 - x + 5 = 81
7x = 81 + 8 - 5 = 84
x = 12.
So the grandson is 12 and Mt Rogers is 8*12 - 3 = 93.

Step-by-step explanation:
The probability of the complement of A is the difference between 1 and P(A):
Answer:
I believe it's B!
Step-by-step explanation:
y=mx+b
y intercept is b
slope is m
y intercept is positive 5
slope is down 2 to the right 3
y= -2/3x+5
So first we see if increase or decrease
180<210
it is increase
then we assume that
percent change
find how much change took place
210-180=30
30/180=x% change
percent means parts out ofo 100s so x%=x/100
30/180=x/100
multiply both sides by 100
3000/180=x
16.66666=x
answe ris 16.6%
