QRST is a parallelogram. Find x and y.
Wewaii [24]

In parallelograms, opposite sides are congruent, meaning that they are the same lengths. So, we have:

y - 4x = 9

-x + 4 = y

Add x to both sides of the second equation:

y + x = 4

y - 4x = 9

This is a system of linear equations. Solve by eliminating the y and subtracting the two equations:

5x = -5

x = -1

Use x to solve for y:

y + (-1) = 4

y = 5

So, x = -1 and y = 5.

Customers who purchase museum tickets in advance receive 10% off the regular admission price. Anias paid a sale price of $54. He
alisha [4.7K]

Answer:

Regular price of a ticket = $60

Step-by-step explanation:

Given:

On purchasing museum tickets in advance customers get 10% off on the regular price of ticket.

Anias paid the sale price of ticket = $54

To find the regular price of ticket.

Solution:

Let the regular price of ticket in dollars be =x

Discount offered for booking in advance = 10%

Discount amount in dollars = Discount\ percent \times Regular\ price=10% \times x =0.10 \times x =0.1x

Sale price of a ticket in dollars= Regular price - Discount amount= x-0.1x=0.9x

Sale price given for a ticket = $54

So, we have:

0.9x=54

Dividing both sides by 0.9

\frac{0.9x}{0.9}=\frac{54}{0.9}

∴ x=60

∴ Regular price of a ticket = $60
