Answer:
Step-by-step explanation:
Let
- x the amount of type A produced;
- y the amount of type B produced;
- z the amount of type C produced.
<u>Cleaning</u> requires 4 minutes for type A, 6 minutes for type B and 8 minutes for type C. In total, 3.5 hours, then
<u>Cutting</u> requires 2 minutes for type A, 4 minutes for type B and 2 minutes for type C. In total, 2.5 hours, then
<u>Packaging</u> requires 2 minutes for type A, 2 minutes for type B and 4 minutes for type C. In total, 1.5 hours, then
Note that
Hence, we have 6 inequalities:
The correct answer is the <u>left</u><u> </u><u>graph</u>.
In the given system of equations, the value of x is 7.334 and the value of y is 7.714
<h3>Solving system of linear equations</h3>
From the question, we are to solve the given system of linear equations
The given system of linear equations is
3x + 7y = 76 ------------ (1)
9y + 5y = 108 ------------ (2)
From equation (2), solve for y
9y+ 5y = 108
14y = 108
y = 108/14
y = 7.714
Substitute the value of x into equation (1), to determine the value of x
3x + 7y = 76
3x + 7(7.714) = 76
3x + 53.998 = 76
Subtract 53.998 from both sides of the equation
3x + 53.998 - 53.998 = 76 - 53.998
3x = 22.002
Divide both sides of the equation by 3
3x/3 = 22.002/3
x = 7.334
Therefore,
x = 7.334 and y = 7.714

The first one is a common multiple and I don't think I can see the rest of question two.
