Answer:

one binder for $3.70

Step-by-step explanation:

The cost of 5 binders and 3 folders = $23.00

The cost of 5 binders and 1 folder = $20.00   [ 2 folders less ]

Cost of 2 folders = 23 - 20 = $3.00

Cost of 1 folder = \frac{3}{2} = $1.50

The cost of 5 binders = 20.00 - 1.50 = $18.50

The cost of 1 binder = \frac{18.50}{5}

                                = $3.70

The cost of one binder is $3.70

aksik [14]

Answer:

Rounded to the nearest integer, the company has a total of 82,958 employees.

Step-by-step explanation:

Given that an international company has 25,800 employees in one country, if this represents 31.1% of the companies employees, to determine how many employees does it have in total, the following calculation must be performed:

31.1 = 25,800

100 = X

100 x 25,800 / 31.1 = X

2,580,000 / 31.1 = X

82,958.1 = X

Thus, rounded to the nearest integer, the company has a total of 82,958 employees.

Solve for x<br> 2/(7x) = 6/5<br><br> 5/21<br> -21/5<br> 21/5<br> I don't know<br> - 5/21
djverab [1.8K]
The answer is:  [A]:  " \frac{5}{21} " .
________________________________________
Given: 

2/ (7x) = 6/5; 

→  (6/5) * (7x) = 2 ; 

42x / 5 = 2 ; 

42x = 2*5 ; 

42x = 10 ; 

42x /42 = 10/42 ; 

x = 10/42 = (10÷2) / (42÷2) = 5/21 ; 

x = \frac{5}{21} ;

→  which is:  Answer choice:  [A]:  " \frac{5}{21} " .
