the first option is the answer

Step-by-step explanation:

4c + 6a <= 120 [building hours]

A theater is selling tickets for a performance. Mr. Smith purchased 8 senior tickets and 5 child tickets for $136 for his friend

ICE Princess25 [194]

Answer:

The price of a senior ticket is $12.

Step-by-step explanation:

Given:

Mr. Smith purchased 8 senior tickets and 5 child tickets for $136. Mr. Jackson purchased 4 senior tickets and 6 child tickets for $96.

Now, to get what is the price of a senior ticket.

Let the senior ticket be $x$ and the child ticket be $y$ :

So, according to question

$8x+5y=136$ .........(1)

$4x+6y=96$ ...........(2)

Now, we have system of equations:

Multiplying the equation (2) by -2 we get:

$-8x-12y=-192$ .......(3)

Now, adding the equation (3) and (1) the variables and the numbers:

$-8x-12y+8x+5y=-192+136$

$-7y=-56$

Dividing both sides by -7 we get:

$y=8$

Putting the value of y in equation (2) we get:

$4x+6(8)=96$

$4x+48=96$

On solving the equation we get:

$x=12$ .

Therefore, the price of a senior ticket is $12.

Select the statement that best describes each multiplication problem

Naily [24]

Answer:

1. Perfect Square

2. Perfect Square

3. Conjugate

4. Conjugate

5. Perfect Square

-I am about 98% sure about these answers.

-An example for a perfect square is (5x+3)(5x+3) and an example for a conjugate is (5x+3)(5x-3). The only difference between the two is the symbol for the second pair of parenthesis.
