Answer:

27 and 39.

Step-by-step explanation:

Let x be the smaller number and y be the larger number.

It is given that sum of two numbers is 66.

x+y=66

y=66-x        .... (1)

Two times the smaller number is 15 more than the larger number.  

2x=15+y         ... (2)

From (1) and (2) we get

2x=15+(66-x)  

2x=81-x  

2x+x=81  

3x=81

Divide both sides by 3.

x=27

Substitute x=27 in equation (1).

y=66-27

y=39

Therefore, the numbers are 27 and 39.

Here is the set up:

Let x and y be the two numbers with x the smaller and y the larger number.

x + y = 66

2x = y + 15

We have two equations in two unknowns.

Take it from here.

Three times a number, less twice the number and 9 is 17. What is the number?
Harlamova29_29 [7]
I believe your answer is 8.

Three times a number less than twice the number and nine is seventeen can be written as: 3n - 2n + 9 = 17

Solve for n as follows:

3n - 2n = n 

n + 9 = 17

17 - 9 = 8

Hope this helps! :)

Health club A charges $60 yearly enrollment fee and $2 per visit. Health club B charges $20 yearly enrollment fee and &amp;4 per
atroni [7]

Answer:

  20 visits

Step-by-step explanation:

The club that charges $40 more for enrollment charges $2 less per visit. The savings on visits is equal to the extra enrollment charge when the number of visits is 40/2 = 20.

For 20 visits, the cost at both clubs is the same.

__

If you let v represent the number of visits, ...

  A = 60 +2v . . . . cost at club A

  B = 20 +4v . . . . cost at club B

  A = B   ⇒   60 +2v = 20 +4v . . . . . . costs are the same for "v" visits

  40 = 2v . . . . . . . subtract 20+2v from both sides

  40/2 = v = 20 . . . . . . same as "word solution" above
