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?

tresset_1 [31]

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

Simplify: -|-15| please answer correctly i'll give brainliest and 5-star rating.

12345 [234]

Answer:

-15

Step-by-step explanation:

Definition of absolute value:

Distance from zero on a number line.

Imagine a number line with 0 in the middle of it. Now mark the number 3 on it. Also mark the opposite of 3, which is -3. What is the distance from zero to those 2 points? it's 3.

This is exactly like saying |3| = 3 and |-3| = 3

Even if the number inside absolute value is negative, it simplifies to the positive of the same number.

_______________________________

So let's talk about your problem.

-|-15|

> the absolute value simplifies to 15

-|-15| = - 15

So that ends up being your answer.

$-15$

Hope this helps!!!!!!!
