Equation/Question:

-2(x+1)+4x<-10 What’s the solution?

Answer/Way I did it:

1. Expand.

-2x-2+4x<-10

2. Simplify -2x-2+4x to 2x-2.

2x-2<-10

3. Add 2 to both sides.

2x<-10+2

4. Simplify -10+2 to −8.

2x<-8

5. Divide both sides by 2.

x<-8/2

6. Simplify 8/2 to 4.

x<−4

Question:

The driving distance between Manchester and London is 195 miles. Faris intends to travel from Manchester to London by coach. The coach will leave Manchester at 3:30 pm. Faris assumes that the coach will travel at an average speed of 50 mph; using his assumption workout Faris’s arrival time in London

Answer:

$Arrival = 7:24pm$

Step-by-step explanation:

Given

$Distance = 195\ miles$

$Speed = 50mi/hr$

$Take\ off = 3:30\ pm$

Required

Determine the time of arrival

First, we need to calculate the time to complete the journey.

$Speed = \frac{Distance}{Time}$

Make Time the subject

$Time= \frac{Distance}{Speed }$

Substitute values for Distance and Speed

$Time= \frac{195mi}{50mi/hr}$

$Time= 3.9hr$

The arrival time is:

$Arrival = Take\ off + Time\ Taken$

$Arrival = 3:30pm + 3.9\ hours$

Split

$Arrival = 3:30pm + 3\ hours + 0.9\ hours$

$Arrival = 6:30pm + 0.9\ hours$

Convert 0.9 hours to minutes

$Arrival = 6:30pm + 0.9 * 60\ mins$

$Arrival = 6:30pm + 54\ mins$

$Arrival = 7:24pm$

frozen [14]

Answer:

Find attached missing part of the question:

The option gpe is best when the contracted volume is below 31250 units

The option fms is best when the contracted volume is between 31,250 and 230,000 units

The option DM is best when contracted volume is above 230,000 units

Step-by-step explanation:

let x represent the volume produced in each of the three options:

Total cost(TC) =fixed cost+(variable per unit*x)

for general purpose equipment:

TC=125,000+18x equation 1

for flexible manufacturing system

TC=250,000+14x equation 2

for dedicated machine

TC=480,000+13x equation 3

if we set equations 1 and 2 together

125,000+18x=250,000+14x

If we equate equations 2 and 3 together

250,000+14x=480,000+13x

14x-13x=480,000-250,000

x=230,000

18x-14x=250,000-125,000

4x=125,000

divide both sides y 4

x=125,000/4=31250

At a movie theater, the adult ticket price is $8 and the child ticket price is $6. for a certain movie, 210 tickets were sold an

fredd [130]

Given,
Adult Price(x) =8 $
Child Price(y) =6 $
So, 8x+6y=1500$ and also given 210 tickets were sold
So, x+y=210
By solving those two equations we get
No.of adult tickets sold = 120 & no.of child tickets =90
