Answer:


Step-by-step explanation:
Arrange the equations so that all the variables are in columns (x as the first column, y as the second, equals a number as the third):
-11x - 4y = 36
5x + 5y = -10
Define and edit Matrix A. We need a 3 x 2 matrix. Input the coefficients and constant:
![\left[\begin{array}{ccc}-11&-4&36\\5&5&-10\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-11%26-4%2636%5C%5C5%265%26-10%5Cend%7Barray%7D%5Cright%5D)
Find rref function, enter matrix A: rref([A]) (press enter)
This gives you:
![\left[\begin{array}{ccc}1&0&-\frac{44}{7}\\0&1&\frac{58}{7}\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D1%260%26-%5Cfrac%7B44%7D%7B7%7D%5C%5C0%261%26%5Cfrac%7B58%7D%7B7%7D%5Cend%7Barray%7D%5Cright%5D)
which means:


Answer:
3 bowls
Step-by-step explanation:
Do 300 mil x 8 jars
2400 mil or 2.4 litter
Since you can't have .4 litters of soup, and we need to heat the soup with 3 bowls
P(B|A) = P(A and B)/P(A)
So to find P(A and B) just multiply P(B|A) by P(A)
P(A and B) = 0.45*0.46 = 0.207
5×3×7= 105
105 ÷ 0.125= 840
840 pieces of popcorn will fit in a 5 inch by 3 inch by 7 inch bag.
