down 3 unit mean -3 outside root
right 2 unit mean -2 inside root,
so the answer is
9. 2.86600.... that is all i know so far
Here! not sure if it's right but i'm pretty confident. boom
Write an equation system based on the problem
"Agatha is five times older than her son, Bob" could be written as:
a = 5b.......(first equation)
"Three years ago, she was nine times older" could be written as:
a - 3 = 9(b - 3)......(second equation)
Solve the equation system
To find the value of b, substitute 5b as a to the second equation
a - 3 = 9(b - 3)
5b - 3 = 9(b - 3)
5b - 3 = 9b - 27
5b - 9b = -27 + 3
-4b = -24
b = -24/-4
b = 6
Her son, Bob, is 6 years old
To find Agatha's age, substitute the value of b to the first equation
a = 5b
a = 5 × 6
a = 30
Agatha is 30 years old
Answer: I hope this helps :)
Step-by-step explanation:
All in all, this leaves us with #(Heart or Face card) = 13+12–3=22 cards.
So your probability would be p(Heart or Face card)= 22/52 or 11/26 or 42,3%
(but they are all the same)
