A total of 644 tickets were sold for the school play. They were either adult tickets or student tickets. There were 56 fewer stu dent tickets sold than adult tickets. How many adult tickets were sold?
2 answers:
Create formulas!
x=number of adult tickets
y=number of student tickets
x+y=644 <em>total sold </em>
56+y=x <em>student was 56 less than adult </em>
Perform substitution
(56+y)+y=644
56+2y=644
2y=588
y=294
Substitute y into the formula we created
x+294=644
x=350
350 adult tickets were sold.
Answer:
Step-by-step explanation:
Let x be the number of adult tickets.
Number of student tickets = 56 fewer than adult tickets
= x - 56
Total tickets = 644
x + (x - 56) = 644
x + x - 56 = 644
2x - 56 = 644
Add 56 to both sides
2x - 56 + 56 = 644 + 56
2x = 700
Divide both sides by 2
2x/2 = 700/2
x = 350
350 adult tickets were sold

Answer:
The ramainder is equal -86
Step-by-step explanation:
Since the polynomial degree Q(x) is 1, the remainder of the division must be a number. Therefore we only need to calculate the value of polynomial for x = -2
180 minus 90 equals 90, divided by 2, the answer is 45 degrees
Pretty sure the answer would be 32. It’s basic subtraction I think.
