Mr. Killian is buying tickets for a school field trip. He buys 80 student tickets, and 15 adult tickets. The cost of a ticket for a student is $8 less than the cost of an adult ticket. He pays an additional charge of $14.75 in taxes and fees. If his total bill comes to $405, choose equation Mr. Killian can use to determine the cost of an adult ticket, x and solve it.
95x - 8 + 14.75 = 405
95(x - 8) + 14.75 = 405
15x + 80(x-8) + 14.75 = 405
2(x-8) + 80x + 14.75 = 405

132 days to 125.4 days percent of change
Answers
Answer:
132 days to 125.4 days percent of change
Step-by-step explanation:
p= N-O/O x 100% where p is the percent change, is the New value and O is
the Old value. We are given the Old value (132) and the New value (125.4) which we can substitute into the formula to calculate the percent change:
p= 125.4-132/132 x 100%
p= -6.6/132 x 100%
p= (-660/132%)
p= -5%

Drag each rational number to the correct location on the table.

Answers
Answer:
+1/-7 = negative irrational
+4/+5 = positive rational
-1/-7 = positive irrational
-4/+5 = negative rational
-1/+7 = negative irrational
+1/+7 = positive irrational
+4/-5 = negative rational
-4/-5 = positive rational
Step-by-step explanation:
so when this problem there is only the fractions 1/7 and 4/5
we know that 1/7 is irrational and 4/5 is a rational this is because 1/7 if you put it in a calculator it has a lot of decimals numbers behind it . you can just memorize this though . 4/5 however is 0.2 which is a rational number . you can do this from long division or put it in a calculator to get 0.2.
now for the positive and negative part of this problem we know that
1) a negative and a negative make a positive
2) a positive and a negative make a negative
3) a positive and a positive make a positive
using these we know that when a fraction has a negative in the denominator you can also put that out front and it will be the fraction as negative . however if there are negatives in both the numerator and the denominator then the fraction is positive because the negatives cancel .
+1/-7 = negative irrational
+4/+5 = positive rational
-1/-7 = positive irrational
-4/+5 = negative rational
-1/+7 = negative irrational
+1/+7 = positive irrational
+4/-5 = negative rational
-4/-5 = positive rational
Answer:
+1/-7 = negative irrational
+4/+5 = positive rational
-1/-7 = positive irrational
-4/+5 = negative rational
-1/+7 = negative irrational
+1/+7 = positive irrational
+4/-5 = negative rational
-4/-5 = positive rational
