One positive number is 3 more than twice another. If their product is 629, find the numbers.
Soloha48 [4]

Answer:

17,37

Step-by-step explanation:

one number = x

The positive number = 2x + 3

x * (2x+3) = 629

x*2x + x *3 = 629

2x² + 3x - 629 = 0

2x² - 34x + 37x - 17*37 =0

2x*(x -17) + 37(x - 17) = 0

(x - 17)(2x + 37) = 0

x - 17 = 0 ;     Ignore  2x + 37 as s is a positive number

x = 17

Positive number = 2*17 +3 = 34+3 = 37

The total employment for police officers in 2006 was 648,000. If there are 719,000 police officers in 2016, what will the percen
Lubov Fominskaja [6]
If you increase the number of police officers from 648,000 to 719,000...you have increased the total employment by 719,000 minus 648,000 
= 71,000

You want to see how much the percentage increase was from 2006 to 2016, so you use your 2006 value of police officers to find the percentage increase.

So you divide 71,000 by 648,000 and multiply by 100 
=10.957%

Rounded off to 10.96% which is your final answer
