What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
We know that the Total number of seats = Total of rows × Number of seats in each row
Let the total number of rows be y. The theater has 384 seats and each row has 16 seats then we get;
384= y × 16
y= 384/16= 24
There are 24 rows each having 16 seats making the total of 384.
Area= length × width
Area 1= 320= 16 × 20
Area 2 = 64
Then;
64 = 16 x
x= 64/16= 4

For Emily’s birthday, her father treated her and five friends to a dinner at a restaurant at the mall. Emily and her friends ordered three pizza dinners at $6.25 each and three chicken baskets at $7.50 each. All six people ordered soft drinks costing $1.25 each. The sales tax on the meal was 4.5%, and the tip was 15%. What was the total cost of the meal, including the sales tax and the tip?
Answer:
$58.58
Step-by-step explanation:
the meal was $48.75
the tax was 4.5%
Multiply 48.75 by 4.5 as a decimal to do this divide 4.5 by 100 = 0.045
48.75 x 0.045 = 2.19375 round to the nearest hundreth = 2.19
48.75 + 2.19 = 50.94
tip on tax = 58.58

Answer:
x=31
Step-by-step explanation:
Since these angles are on a straight line, they are supplementary (combine to make 180 degrees. Therefore we can set up an equation to find x.
(5x-16)+(x+10)=180
Drop the parentheses.
5x-16+x+10=180
Combine like terms.
6x-6=180
Add 6 to both sides.
6x=186
Divide both sides by 6.
x=31
