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.
90 - 40 = 50
Complementary angles add up to 90 degrees.
If one angle is 40 degrees less than the other, you just put it into an equation where 40 is subtracted from 90.
The answer would then be 50 degrees.
30, 60, 90
a. What possible jersey numbers does Frank wear.
b. its a multiple 10 and has 3 for one of its factors and its a 2-digit number,
c. By eliminating all the incorrect answers?
d. Number on, 10, 3, and frank could have 30, 60, or 90.
3x + 8
Because you do not know the number so it is x
