Wait for area, wouldn't you just times 13 and 5 and get 65 and then times 23?
Answer:
(7, 6)
Step-by-step explanation:
multiply first eq. by 3 to get 6x - 3y = 60
now do
6x + 3y = 60
- 6x - 5y = 12
--------------------
8y = 48
solve for y: y = 6
with this y value, plug it in to the first equation (easier to solve) and get 2x + 6 = 20
solve for x and get x = 7
so ans is (7, 6)
All possible outcomes - 6
odd number - 3
probability -
12 divided my 8 makes 1.5
