Solve for x in the literal equation −5 = xy + z.

Answers

Answer: x = -5 -z/y or x= -5/y - z/y

Step-by-step explanation:

-5 = xy + z -- then you need to isolate the x, so subtract z from both sides

-5-z = xy -- then divide both sides by y

x= -5-z/y

At the beginning of the day the stock market goes down 30 3/4 points and stays at this level for most of the day.

Answers

Complete question:

At the beginning of the day the stock market goes down 30 3/4 points and stays at this level for most of the day. At the end of the day the stock market  goes up 100 1/2 points from the low at the beginning of the day. What is the total change in the stock market from the beginning of the day to the end of the​ day?

Answer:

The total change in the stock market is [tex]69\frac{3}{4}[/tex]

Step-by-step explanation:

Given;

the stock market at the beginning of the day =  30 3/4 points

the stock market at the end of the day = 100 1/2 points

The total change in the stock market from the beginning of the day to the end of the​ day is given by;

100 1/2 points - 30 3/4 points

[tex]= (100 -30) + (\frac{1}{2} -\frac{3}{4} )\\\\= 70 + (-\frac{1}{4} )\\\\= 70 - \frac{1}{4}\\\\= 69\frac{3}{4}[/tex]

Therefore, the total change in the stock market is [tex]69\frac{3}{4}[/tex]

15 men can do a piece of work in 80 days. If 5 more men are added, how long will it take to complete same piece of work?​

Answers

Answer:

Step-by-step explanation:

This is an inverse proportion.

men = k / Time         So first we need to find k

k = men * Time         Substitute values

k = 15*80

k = 1200  Notice the units are man days.

Now what happens if we increase the number of men to 20? What happens to the number of days.

20 = 1200 / time          Multiply both sides by time

20*time = 1200            Now divide by 20

time = 1200/20

Answer: time = 60 days
