Answer:tony was billed for 154 minutes.
Step-by-step explanation:
Let x represent the number of minutes for which Tony was billed.
For his long distance phone service, Tony pays an $8 monthly fee plus 6 cents per minute. Converting 6 cents to dollars, it becomes 6/100 = $0.06
This means that if he made x minutes of long distance call in a month, the total cost would be
8 + 0.06x
Last month, Tony's long distance bill was $17.24. It means that
8 + 0.06x = 17.24
0.06x = 17.24 - 8 = 9.24
x = 9.24/0.06
x = 154
Because they are in the center.
3x - 4y = 7
-(3x + 2y = -5)
= 0 - 6y = 12
-6y = 12
y = -2
The resulting equation would be y = -2.

Step-by-step explanation:
n (U)=2000
n (A)=50% of 2000
=(50÷100)×2000
= 1000
n( B) = 40%
= (40÷100)×2000
= 800
n(AuB)(compliment) = 15%
=(15÷100)×2000
=300
