Answer:
first thing to do is combine like terms
now you would have -x-4=4
this is because you added -6x+5x
now you would add 4 to each side
now you would have-x=8
then you would divide the negative because x has to be positive
now you would have x= -8
that is your answer. if you any questions just ask :D
Step-by-step explanation:
Total of 2.7. ---Anna had 0.5 Sam 0.75 Michelle 0.45 and Paige 0.70
For both Carnivals to have the same cost, 10 tickets will have to be purchased.
Carnival M :
Entrance fee = $5.00
Cost per ticket = $0.50
Carnival P :
Entrance fee = $7.00
Cost per ticket = $0.30
Let the Number of ticket = n
Cost of n Carnival M tickets :
5 + 0.50n - - - (1)
Cost of n Carnival P tickets :
7 + 0.30n - - - (2)
Value of n in other to have the same price :
(1) = (2)
5 + 0.50n = 7 + 0.30n
Collect like terms
0.50n - 0.30n = 7 - 5
0.20n = 2
Divide both sides by 0.20
n = 2 / 0.20
n = 10
Therefore, 10 tickets has to be purchased for both Carnivals to have the same cost.

Answer:
Step-by-step explanation:
<u>Line 1</u>
- -3x + 5y = -4
- 5y = 3x - 4
- y = 3/5x - 4/5
<u>Line 2</u>
- px + 25 y = 4
- 25y = -px + 4
- y = -p/25x + 4/25
<u>The system is inconsistent if slopes are same, so we should have:</u>
- 3/5 = - p/25
- 25*3/5 = -25p/25
- 15 = -p
- p = -15
