The answer would be 58
180 - 65 - 57 = 58 which is the missing angle
Answer:
$0.50
Solution:
First lets find how many cookies there are:
2.5*12= 30 cookies
Then we divide cost by cookie to see how much a cookie costs
$15/30 = $0.50

Elimination Method
If we multiply the equation 3 by (-1) we obtain this:
If we add them we obtain 0, therefore there are infinite solutions. So, let's write it in terms of Z
1. Using the 3rd equation we can obtain X(Y,Z)
2. We can replace this value of X in the 1st and 2nd equations
3. If we simplify:
4. We can obtain Y from this two equations:
5. Now, we need to obtain X(Z). We can replace Y in X(Y,Z)
6. If we simplify, we obtain:
7. In conclusion, we obtain that
(X,Y,Z) =
