Answer:
It would be D, because you have 12 students who have tickets worth n amount, and all of them get a discount of $5.00 off. You would there have 12 times the number of tickets (n) minus $5.00 off from your discount
Step-by-step explanation:
B.)155
a1+d(n-1)
a1+d(6-1)=50
a1+5d=50
a1+d(11-1)=85
a1+10d=85
a1=50-5d
(50-5d)+10d=85
50-5d+10d=85
5d+50=85
5d=35
d=7
a1+7(6-1)=50
a1+35=50
a1=15
15+7(n-1)
15+7(21-1)
15+7(20)
15+140=155
Answer:
75.8 is your answer
Step-by-step explanation:
119:157*100 =
(119*100):157 =
11900:157 = 75.8
Check the picture below.
notice that, the diagonal is really just a traverse line cutting through the parallel segments of AB and DC, and since those angles are alternate interior ones, that means 5y - 1 = 7y - 15, and 6x - 6 = 4x + 2, therefore
