x + y = 23

x = 2y-1

y + 2y-1 =23

3y-1 =23

3y =24

y = 24/3 =8

 y = 8

 x = 2*8-1 = 15

15+8 = 23

 the 2 numbers are 8 & 15

Let the two numbers be x and y.

Given,

x + y = 23

x = 23 - y

Also given,

y = 2x - 1

y= 2(23 -y) -1

y = 46 - 2y - 1

3y = 45

y = 15

x = 23 - y = 23 - 15 = 8

Hence, the two numbers are 15 and 8.

Find and compare the growth rates in the weekly number of specialty items produced at each factory.
DerKrebs [107]

0.129 is the change in the growth rate of company.

According to statement

we have to find and compare the growth rate of the company weekly.

we use the growth rate formula is

GROWTH RATE = present - past / present

Substitute the values in this formula

1st week = 220-190 / 220

1st week = 0.136

2nd week = 252-220 / 252

2nd week = 32 / 252

2nd week = 0.126

3rd week = 290-252 / 290

3rd week = 0.131

4th week = 337 - 290 / 337

4th week = 0.139

5th week = 380 - 337 / 380

5th week = 0.113

6th week = 440 - 380 / 440

6th week = 0.136

7th week = 505 - 440 / 505

7th week = 0.128

Now we find the average value of growth rate

Average = 0.136 + 0.126+0.131+0.139+0.113+0.136+0.128 /7

Average = 0.909/7

Average = 0.129

So, 0.129 is the change in the growth rate of company.

It's the first choice.  If you multiply the first equation by 3, your y term is a +12, and if you multiply the second equation by 4, your y term is a -12.  When you add them the y terms cancel each other out.
