Distribute:
-4x+28=36

Subtract 28 from both sides:
-4x=8

Divide both sides by -4;
x=-2

Answer:

Value of x in the expression -4(x-7) = 36 is -2 .

Step-by-step explanation:

As given the expression in the question be as follow .

-4(x-7) = 36

First open the bracket and simplify the terms

-4 × x -4 × -7 = 36

-4x + 28 = 36

-4x = 36 -28

-4x = 8

Solving the above

x = \frac{-8}{4}

x = -2

Therefore the value of x in the expression -4(x-7) = 36 is -2 .

The angle measurements in the diagram are represented by the following expressions
krok68 [10]

Answer:

/A = 30°

/B = 150°

Step-by-step explanation:

Given that the lines are parellel.

Then /A+/B = 180° ( Consecutive interior angles)

Putting given values of angles

6x-18+ 14x+38 = 180

20x + 20 =180

20x = 160

x = 8

/A = 6x-18 = 6×8-18 = 30°

/B = 14x+38 = 14 × 8 +38 = 150°

Problem 11-93 Waltner Corporation s management... Waltner Corporation's management reports that its average delivery cycle time
Marat540 [252]

Complete question is;

Waltner Corporation's management reports that its average delivery cycle time is 25 days, its average throughput time is 7.7 days, its manufacturing cycle efficiency (MCE) is 0.43, its average move time is 0.3 day, and its average queue time is 3.00 days. Required: a. What is the wait time?

b. What is the process time?

c. What is the inspection time?

Answer:

A) Wait time = 17.3 days

B) Process time = 3.311 days

C) Inspection time = 0.789 days

Step-by-step explanation:

A) we are given;

Delivery cycle time = 25 days

throughput time = 7.7 days

The formula for wait time is calculated from;

Delivery time = wait time + throughput time

So, wait time = Delivery time - throughput time

Wait time = 25 - 7.7 = 17.3 days

B) The process time is calculated from;

MCE = Process time/throughput time

So, process time = MCE x throughput time

We are given MCE = 0.43,thus, and we already know throughput time. Thus;

Process time = 0.43 x 7.7 = 3.311 days

C) The inspection time is gotten from;

throughput time = Process time + Inspection time + Move time + Queue time

Making inspection time the subject;

inspection time = throughput time - Process time - Move time - Queue time

Move time = 0.3 days

Queue time = 3 days.

Thus;

inspection time = 7.7 - 3.311 - 0.3 - 3.3 = 0.789 days
