Evaluate x(y+3)/(3+y)z for x=12, y=1, and z=6.

A) 2

B) 5

C) 8

D) 6

Answer:

2

Step-by-step explanation:

We take the equation

[tex]x(y+3)/(3+y)z[/tex]

and substitute the values for each individual variable in the problem. It looks like this:

[tex]12(1+3)/(3+1)6[/tex]

Now we can solve the equation.

When solved, it equals 2.

What are the solutions to the equation x-7/x=6?

x= -7 and x = 1
x= -6 and x = -1
x = -1 and x = 7
0 x = 1 and x = 6

Solve for the “x” in all the equation below. Show ALL work.
(1) - 2.x+8+ 7x = 48
(2) -15=r-6x +10
(3) - 8+ 2x - 4x + 2 = -16

The logistics/operations manager of a mail order house purchases two products for resale: King Beds (K) and Queen Beds (Q). Each King Bed costs $500 and requires 100 cubic feet of storage space, and each Queen Bed costs $300 and requires 90 cubic feet of storage space. The manager has $75,000 to invest in beds this week, and her warehouse has 18,000 cubic feet available for storage. For every Queen Size Mattress purchased, they need to purchase at least twice as many King Size Mattresses. Profit for each King Bed is $300, and for each Queen Bed is $150.
18) What is the objective function?
A. Z = $150K + $300Q
B. Z = $500K + $300Q
C. Z = $300K + $150Q
D. Z = $300K + $500Q
E. Z = $100K + $90Q
19) What is the storage space constraint?
A. 200K + 100Q ? 18,000
B. 200K + 90Q ? 18,000
C. 300K + 90Q ? 18,000
D. 500K + 100Q ? 18,000
E. 100K + 90Q ? 18,000
20) Which of the following is not a feasible purchase combination?
A. 0 King Beds and 0 Queen Beds
B. 0 King Beds and 250 Queen Beds
C. 150 King Beds and 0 Queen Beds
D. 90 King Beds and 100 Queen Beds
E. 0 King Beds and 200 Queen Beds
