Let their ages be g and k.  Then g = k + 3.

Next:  (g+7) + (k+7) = 41.

Substituting k + 3 for g in the above equation, we get  k + 3 + 7 + k + 7 = 41.

Combining like terms:  2k + 17 = 41.  Then 2k = 24, and k = 12.

Kevin is 12 years old and Greg is 15 years.

The first and third quartiles
aalyn [17]
1.  You'll need to download this data, or copy it down by hand.
2.  Rearrange the data from lowest to highest values.
3.  You have 24 data points (an even number). 
       In this case, to find the 1st quadrant, take the left half (that is, the left 12) data points.  Since 12 is an even number, you must find the average of the middle two of these 12 data points.  Your result is the 1st quadrant.
      To find the 3rd quadrant, find the middle two data points of the right-hand 12 data points.  Average these two points.  The result is the 3rd quadrant.

For what values of X are the statements below true
Galina-37 [17]

Answer:

See solutions below

Step-by-step explanation:

For what values of X are the statements below true

A. 1x>x+1

x >x+1

x-x>1

0x > 1

x > 1/0

X >∞

B) |1-x|>3

The fucntion can both be positive and negative

For the negative function

-(1-x) > 3

-1+x > 3

x > 3+1

x > 4

For the positive function

1-x > 3

-x > 3 - 1

-x > 2

x < -2

Hence the required solutions are x > 4 and x < -2

c) For the equation

|x-15| < 0

-(x - 15) < 0

-x + 15 < 0

-x < -15

x > 15

Also x-15 < 0

x < 0+15

x < 15

Hence the required solution is x > 15 and x < 15
