Solution:

As per the problem

A person is born every 5 seconds and a person dies every 12 seconds.

Here the LCD of 5 and 12 is 60.

The number of person born in 60 seconds=\frac{60}{5}=12\\

The Number of person died in 12 seconds=\frac{60}{12}=5

Hence Population increase in 60 seconds is=12-5=7\\

Hence time required to increase the population by one =\frac{60}{7} \ \ seconds\\

Please help, need to find x and y :))
blondinia [14]

Answer:

x=14

y=140

Step-by-step explanation:

Using (9x+14) + (3x-2) = 180, we can solve this equation.

First add like values giving you 12x+12=180. Then subtract 12 from both sides giving you 12x=168.

Then divide both sides by 12 giving you x=14.

Finally, just simply set 9x+14 equal to y and substitute x for 14. This gives you 140=y

Hope this helped

ZanzabumX [31]

Answer:

  • x = -0.6

Step-by-step Solution:

<u>Isolate the variable x to get the answer.</u>

  • x − 2/5 = −1
  • => x = -1 + 2/5
  • => x = -1 + 0.4
  • => x = -0.6

Hence, the value of x is -0.6.

Abby has x dolls. Lauren has 9 times as many as Abby. Betsy has 7 fewer than Lauren. How many dolls do they have in all?
makkiz [27]

Answer: x + 9x + (9x - 7)

Simplified: 19x - 7

Step-by-step explanation: We see that Abby already starts off with x dolls. We put a 9 infront of the x for the second part of the expression because Lauren has 9 times as many dolls as Abby. Since Betsy has 7 less than Lauren, we take away 7 from 9x. We put that part in parenthesis because that part needs to be done first before we add everything together. Once simplified, we have "19x - 7". (I really tried my best so I hope this is the correct answer!)
