Feliz [49]

Answer:

The greatest number of stamps that Nathan can put on each page = 16.

Step-by-step explanation:

Given:

Nathan has:

80 US stamps

64 Canadian stamps

32 Mexican stamps

The stamps need to put on a page such that each page has same number of same country stamps on each page.

To find the greatest number of stamps he can put on each page.

Solution:

In order to find the greatest number of stamps Nathan can put on each page, we will find the G.C.F. of the three numbers.

The numbers are:

$80,64,32$

<em>We will list down the prime factors of each number.</em>

$80=2\times 2\times 2\times 2\times 5$

$64=2\times 2\times 2\times 2\times 2\times 2$

$32=2\times 2\times2\times 2\times 2$

The G.C.F can be given as = $2\times 2\times 2\times 2$ = 16

Thus, the greatest number of stamps that Nathan can put on each page = 16.

Set up a system of linear equations, and then solve for the indicated quantities.

hichkok12 [17]

9514 1404 393

Answer:

smaller: -4
larger: -1

Step-by-step explanation:

Substituting the given variables into the word problem, we have two equations:

3x +3y = -15

6x -3y = -21

Adding these equations eliminates y:

9x = -36

x = -4 . . . . divide by 9

Using this in the first equation, we have ...

3(-4) +3y = -15

-4 +y = -5 . . . . . divide by 3

y = -1 . . . . . . . . . add 4

The smaller number is -4; the larger is -1.

Illustrative Example 1:

dlinn [17]

Given:

The data set is:

87, 84, 85, 85, 86, 90, 79, 82, 78, 76

To find:

The mode of the given data set.

Solution:

We have,

87, 84, 85, 85, 86, 90, 79, 82, 78, 76

Arrange the data values in the ascending order.

76, 78, 79, 82, 84, 85, 85, 86, 87, 90

We know that the mode of date set is the most frequency value of the data set.

From the above data set it is clear that the number 85 has the highest frequency 2.

Therefore, the mode of the data set is 85.

Financial planners recommend that families save about 5% of their take-home pay. Ed and Sherrie save $90 each pay period from th

Ratling [72]

Answer:

Ed and Sheerie save 7.5%.

Step-by-step explanation:

This question can be solved using a rule of three.

Ed and Sherrie save $90 each pay period from their combined paychecks, which total $1200. What percent do Ed and Sherrie save?

How much of $1200 is $90? $1200 is 100% = 1, $90 = x. So

$1200 - 1

$90 - x

$1200x = 90$

$x = \frac{90}{1200}$

$x = 0.075$

Ed and Sheerie save 7.5%.
