Answer:
x = 4.25
Step-by-step explanation:
First, alter the equation until both exponents have the same base. We know that 9^3 is 27. Therefore, we can change 27^(x-3) into 9^3(x-3).
Now, the equation can be written as 9^(8-x) = 9^(3x-9)
Now that the bases are the same, we can cancel them out and just solve for the exponents. This will look like:
8-x = 3x-9.
8 = 4x - 9
17 = 4x
x = 4.25
Answer:
The answer is: Each adult ticket is $7 and each student ticket is $9.
Step-by-step explanation:
Let a = the number of adult tickets. Let s = the number of student tickets.
For day 1:
14a + 1s = $107
Solve for s:
s = 107 - 14a
For day 2:
12a + 5s = $129
By substitution:
12a + 5(107 - 14a) = 129
12a + 535 - 70a = 129
-58a = 129 - 535
-58a = -406
a = -406 / -58 = $7 for adult tickets
Solve for s:
s = 107 - 14a
s = 107 - 14(7)
s = 107 - 98
s = $9 for student tickets
Proofs:
For day 1:
14a + 1s = $107
14(7) + 1(9) = 107
98 + 9 = 107
107 = 107
For day 2:
12a + 5s = $129
12(7) + 5(9) = 129
84 + 45 = 129
129 = 129
