Mathematics

Alona [7]2 years ago

The value of x that would make ABCD a parallelogram is x = 5

<h3>How to find the interior angle of a parallelograms?</h3>

A parallelogram, opposite sides are equal and parallel, which means opposite interior angles are equal.

Opposite sides of a parallelogram are congruent and parallel

Therefore,

5x - 3 = 14x - 48

subtract 5x from both sides

5x - 5x - 3 = 14x - 5x - 48

-3 = 9x - 48

add 48 to both sides

-3 + 48 = 9x - 48 + 48

45 = 9x

x = 45 / 9

x = 5

Therefore, the value of x that would make ABCD a parallelogram is x = 5

For the school play, the advance tickets cost $3, while tickets at the door cost $5. Thirty more tickets were sold at door in ad
Talja [164]

Answer:

<u>310</u> tickets were sold in advance before school pay and <u>340</u> door tickets were sold in advance.

Step-by-step explanation:

Given:

Let number of tickets sold in advance be 'x'.

Cost of advance ticket = $3

Cost of door tickets = $5

Also given:

Thirty more tickets were sold at door in advance

Hence number of door tickets sold = x+30

Total Money Collected = $2630

Now we can say that Total Money Collected is equal to sum of number of tickets sold in advance multiplied by Cost of advance ticket and number of door tickets sold multiplied by Cost of door tickets.

Framing in equation form we get;

3x+(x+30)5=2630

Solving the equation to find the value of x we get;

3x+5x+150=2630

Combining the like terms we get;

3x+5x=2630-150\\\\8x= 2480

Now Dividing 8 on both side using division property we get;

\frac{8x}{8} =\frac{2480}{8}\\ \\x=310

Substituting the value of x to find number of door tickets been sold.

number of door tickets sold = x+30=310+30 =340

Hence, <u>310</u> tickets were sold in advance before school pay and <u>340</u> door tickets were sold in advance.
