Answer:
x ≤ 13.2.
Step-by-step explanation:
6 ≥ x/2.2
Multiply both sides by 2.2:
6 * 2.2 ≥ x
x ≤ 13.2.

Answer:
A. 3×3
B. [0, 1, 5]
C. (rows, columns) = (# equations, # variables) for matrix A; vector x remains unchanged; vector b has a row for each equation.
Step-by-step explanation:
A. The matrix A has a row for each equation and a column for each variable. The entries in each column of a given row are the coefficients of the corresponding variable in the equation the row represents. If the variable is missing, its coefficient is zero.
This system of equations has 3 equations in 3 variables, so matrix A has dimensions ...
A dimensions = (rows, columns) = (# equations, # variables) = (3, 3)
Matrix A is 3×3.
__
B. The second row of A represents the second equation:

The coefficients of the variables are 0, 1, 5. These are the entries in row 2 of matrix A.
__
C. As stated in part A, the size of matrix A will match the number of equations and variables in the system. If the number of variables remains the same, the number of rows of A (and b) will reflect the number of equations. (The number of columns of A (and rows of x) will reflect the number of variables.)
The question is incomplete :
However, assume Number of cups of flower 10
Number of flour cups for each pie 1/4
Answer:
8
Step-by-step explanation:
Number of cups of flower = 10
Number of flower cups per crust pie = 1/4 cups
Since, the cups of flower was divided equally into to 5 containers;
Number of flower cups per container :
10 / 5 = 2
Each container has 2 cups of flower each.
1 container was used in making crust pie :
The number of crust pies made is:
Cups of flower in container / cups of flower per crust pie
= 2 ÷ 1/4
= 2 * 4 /1
= 8 crust pies
