The answer is 1.5
Step-by-step explanation:
Answer: it's not D i thought it was and I got it WRONG!!!
Say the number of adult tickets is x. That means the number of student tickets is 71 less, making it x - 71.
We can add the number of student and adult tickets, because we know their sum is 479.
x + x - 71 = 479
Now, we solve for x.
2x - 71 = 479
2x = 550
x = 275
So, there were 275 adult tickets sold.
A^2+b^2=c^2
a^2+9^2=15^2
a^2+81=225
-81 -81
a^2= 144 (square root both sides)
a=12
