Answer:
Step-by-step explanation:
Set the two unknown numbers to X and Y.
X + Y = 22
2X = 10Y
Rewrite the second equation as: X = 5Y
Now use this in the first equation: 6Y=22
Y = 3.67 [3 2/3]
X = 18.33 [18 1/3]
---------------------------------------
3 2/3 + 18 1/3 = 22, and
2*(18 1/3) = 10*(3 2/3)
Ax - b = c....subtract ax from both sides
-b = -ax + c <==
or it could also have been b = ax - c (but that ones not there)
If the question is asking if only one isnt insured, the chances are 1/12.
If the question is asking if at least one isnt insured, the chances are 1/4.
