Pam says she will charge 125 plus 15 an hour to paint a house. Michelle will charge $50 plus $20 per hour to paint a house. Afte
aniked [119]
Let us assume the number of hours after which the cost of Pam and Michelle will be same = x
Now let us concentrate on the information's already given in the problem.
Fixed charge taken by Pam = $125
Charge per hour taken by Pam = $15
Fixed charge taken by Michelle = $50
Charge per hour taken by Michelle = $20
Then
125 + 15x = 50 + 20x
20x - 15x = 125 - 50
5x = 75
x = 75/5
  = 15
So after 15 hours the charge taken by Pam and Michelle will be the same. I hope the procedure for doing this type of problem is clear to you.

6x + 7y = 1<br> 8x – 3y = 25<br> Solve me fast explainly
Elenna [48]

Answer:

{x,y} = {89/37,-71/37}

Step-by-step explanation:

 8x = 3y + 25

 [2]    x = 3y/8 + 25/8

Plug this in for variable  x  in equation [1]

  [1]    6•(3y/8+25/8) + 7y = 1

  [1]    37y/4 = -71/4

  [1]    37y = -71

Solve equation [1] for the variable  y  

  [1]    37y = - 71

  [1]    y = - 71/37

By now we know this much :

   x = 3y/8+25/8

   y = -71/37

Use the  y  value to solve for  x  

   x = (3/8)(-71/37)+25/8 = 89/37
