There are 17 rows of seats in a cinema. There are 22 seats in each row. A film was shown in the cinema on friday night. Each ticket for the film cost £7.50
The sale of tickets for that night made £2587.50
How many tickets were not sold
Total number of seats = 17 x 22 = 374
Number of tickets sold = £2587.50 / £7.50 = 345
So 345 people filled 345 seats
Unoccupied seats = 374 - 345 = 29

Answer: y=12 x =9
Step-by-step explanation:
In a parallelogram the diagonals bisect each other making them equal.
this means 2y + 6 = 30
we can rearrange this as 30 - 6 = 2y
24 = 2y therefore y = 12
3x - 3 = 24
We can rearrange this as 24 + 3 = 3x
3x = 27
27 / 3 = 9
x = 9

Answer:
(72 divided by 6) + 6
Step-by-step explanation:
78 divided by 6 is 13. The question (72 divided by 6) + 6 does not equal to 13, it equals to 14, therefore (72 divided by 6) + 6 is not equivalent.

Which question below is a Statistical Question?
A. How many students have a cell phone?
B. How many months are in a year?
C. How tall are the students in your class?
D. What is for lunch today?
Answer:
C
Step-by-step explanation:
I chose C because it more detailed than the rest of the question. Everyone already knows how many months are in a year. What is for lunch today is just a normal question. How many students have a cell phone was not really detailed but it would have been different if they said "How many percentage of college students in math class uses cell phones.

What would you multiply to make the y variable cross out?
-5x + y = -3
3x - 8y = 24
Answer:
Step-by-step explanation:
-40x + 8y = -24
3x - 8y = 24
-37x = 0
x = 0
0 + y = -3
y = -3
(0, -3)
Answer:
I will show you how to solve for x and y.
Step-by-step explanation:
-5x + y = -3
3x - 8y = 24
You can isolate y in the first equation, and substitute that into the second equation.
so to isolate y in -5x + y = -3, you would add 5x to both sides
this gives you y = 5x - 3
Then substitute this y into the equation below.
3x - 8(5x-3) = 24 (this way, the y variable disappears)
then distribute the 8 into the bracket
3x - 40x + 24 = 24
combine the variables
-37x + 24 = 24
isolate x by moving the constants to one side
-37x = 0
so x = 0
I am not sure if you want the rest, but here it is.
substitute x = 0 into one of the equations.
-5x + y = -3
-5(0) + y = -3
y = -3

1. If you wish to calculate the interest on an investment with an interest rate
of 2.85%, what number will you plug into your equation?"
0.00285
2.85
0.285
ОО
0.0285
=========================================
Explanation:
You move the decimal point two spots to the left to go from 2.85% to 0.0285
Or you can think of it like this:
2.85% = (2.85)/100 = 0.0285
since "percent" means "per 100"

Graph f (.x) = x3 – 4x3 + x2 + 2. Identify the x-intercepts and the points where the local maximums and local
minimums occur. Determine the intervals for which the function is increasing or decreasing. Round to the nearest
hundredth, if necessary.
After graphing x⁵ – 4x³ + x² + 2, we have
x-intercepts : x ≈ 2.16, x = 1, x ≈ 1.75
local maximums : (-1.63, 10.47)
local minimums : (1.46, -1.68)
increasing : 1.46 < x < -1.63
decreasing : -1.63 < x < 1.46
What is graphing?In discrete mathematics, and mοre specifically in graph theοry, a graph is a structure amοunting tο a set οf οbjects in which sοme pairs οf the οbjects are in sοme sense "related". The οbjects cοrrespοnd tο mathematical abstractiοns called vertices (alsο called nοdes οr pοints) and each οf the related pairs οf vertices is called an edge (alsο called link οr line).
Typically, a graph is depicted in diagrammatic fοrm as a set οf dοts οr circles fοr the vertices, jοined by lines οr curves fοr the edges. Graphs are οne οf the οbjects οf study in discrete mathematics.

What is rotation?Rotation means the circular movement of an object around a center. It is possible to rotate different shapes by an angle around the center point.
Given:
LMNP is rotated 90° clockwise around the origin.
If we rotate the figure in LMNP about 90 degrees then the coordinates will change into
(x, y) to (y, -x).
As, x= 3, y=4
Hence, the coordinates of M is M’(4,-3).
