Tickets to a school play cost $3 for students and $8 for adults. On opening night, $1000 was collected and 150 tickets sold. How

vesna_86 [32]

Let the number of students who bought tickets be s,
Let the number of adults who bought tickets be a,

Equation 1:

$3s \: + \: 8a \: = \: 1000$

Equation 2:

$s \: + \: a \: = \: 150 \\ s \: = \: 150 \: - \: a$

Substitute ( 2 ) into ( 1 ),

$3(150 \: - \: a) \: + \: 8a \: = \: 1000 \\ 450 \: - \: 3a \: + \: 8a \: = \: 1000 \\ 5a \: = \: 550 \\ a \: = \: 110$

Substitute a = 110 into ( 2 ),

$s \: + \: 110 \: = \: 150 \\ s \: = \: 40$

Ans: 40 Student Tickets, 110 Adult Tickets

What is the product of the two integer values for $x$ for which $|x^2 - 16|$ is a prime number?

Nana76 [90]

Answer:

-9

Step-by-step explanation:

x² -16 = (x -4)(x +4)

This magnitude of this product can only be prime if one of the factors is ±1. Any other integer value of x will produce a composite number (or zero).

... For x-4 = ±1, x = 3 or 5

... For x+4 = ±1, x = -3 or -5

The values of x that are ±3 both give |x²-16| = 7, a prime.

The values of x that are ±5 both give |x²-16| = 9, not a prime.

The two values of x that are of interest are x=-3 and x=3. Their product is ...

... (-3)·(3) = -9

A real estate agent receives a 3%

PtichkaEL [24]

you just have to divide the value by 100 and then multiply by 3 (the order doesn't matter tho) so,

131000/100 = 1310 x 3 = 3930

the commission is $3930.00

<em>hope it helps :)</em>
