Answer:
let this happens after t hours
so
80t + 60t = 392
140 t = 392
t = 392/140
=2.8 hours
Answer:
The new cost of tickets after decrease of price at 23 % rate is $ 4.62
Step-by-step explanation:
Given as :
The initial cost of the selling tickets = $ 6
Let The final cost of selling tickets = $ x
The rate of decrease of ticket price = 23 %
Now,
The final cost of tickets = initial cost of tickets × ( 1 -
)
or, $ x = $ 6 × ( 1 -
)
or, x = $ 6 × 
∴ x = $ 4.62
So decrease price = x = $ 4.62
Hence The new cost of tickets after decrease of price at 23 % rate is $ 4.62 Answer
Answer:
30
Step-by-step explanation:
I think that's the answer but if I'm wrong tell me right away I'll try another method.
Subtract 7 from both sides
12 - 7 < n
Simplify 12 - 7 to 5
5 < n
Switch sides
<u>n > 5</u>
Answer: x= -1, y= -3
Step-by-step explanation
solve like a system of equations
x-y-2 = 0
+
x+y+4=0
------------
2x+2=0, 2x= -2, x= -1, then plug that back into either equation
-1+y+4=0, y+3=0, y= -3
