Answer:
-> (x,y) => (1,5)
x = 1y = 5Step-by-step explanation:
Let's solve your system by elimination.
18x−7y=−17;3x−3y=−12
Multiply the second equation by -6, then add the equations together.
(18x−7y=−17)
−6(3x−3y=−12)
Becomes:
18x−7y=−17
−18x+18y=72
Add these equations to eliminate x:
11y=55
Then solve 11y=55for y:
11y=55
11y/11 = 55/11
(Divide both sides by 11)
y=5
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
18x−7y=−17
Substitute5foryin18x−7y=−17:
18x−(7)(5)=−17
18x−35=−17(Simplify both sides of the equation)
18x−35+35=−17+35(Add 35 to both sides)
18x=18
18x/18 = 18/18
(Divide both sides by 18)
x=1

Answer:

Step-by-step explanation:
231 - 7a = 98
How to solve this
Answer:
19
Step-by-step explanation:
231 - 7a = 98 = -7a + 231 = 98
Subtract 231 from both sides to get -7a = -133
Divide by -7 on both sides to get a = 19
Answer:
a = 19 is the correct solution.
Step-by-step explanation:
Step 1 : Start by simplifying both sides of the problem.
231 − 7a = 98
231 + − 7a = 98
−7a + 231 = 98
Step 2 : Next step is to subtract 231 from both sides
−7a + 231 − 231 = 98 − 231
−7a = −133
Step 3: Finally, divide both sides by -7.
( When I use the symbol /, it signifies I'm dividing.)
-7a/-7 = -133/-7
-133 divided by -7 equals 19
This shows that a = 19. I hope this helps! :D

Answer:
The Cost of operating the theater if there are 100 people at a show is 20,000Rs.
Step-by-step explanation:
Theater is a place where the movies are shown in big screens and Speakers are used for the clear audio of the movie.
In a theater there will be 3 to 4 shows for a movie or different movie.
Theater can consist of 250 - 300 seats and can cost up to 250rs for a seat.
Consider a ticket cost of 200rs. For 100 people in a show ,
Cost = 200 × 100
Cost = 20,000.
Hence the cost of operating theater if there are 100 people at a show is 20,000Rs.

It takes staff members 162 minutes total each night to clean all six ovens. If each staff
member works for 18 minutes, how many staff members does it take to clean the
ovens?
Answer:
9
Step-by-step explanation:
If it takes 162 minutes each night to clean all 6 ovens, and each staff member works for 18 minutes each then we have to use division to find out how many staff members it will take to clean the ovens.
First we have to divide 162 by 18 which equals 9. This is a one step problem, so 9 is the answer.
It will take 9 staff members to clean all 6 ovens.
Happy Holidays
It takes 9 staff members to clean all six ovens, with each staff member working for 18 minutes.
Given that total cleaning time is 162 minutes
Time per staff member is 18 minutes
To find the number of staff members (N), we divide the total cleaning time by the time per staff member:
N = Total cleaning time / Time per staff member
N = 162 minutes / 18 minutes
N = 9
Therefore, it takes 9 staff members to clean all six ovens, with each staff member working for 18 minutes.

The length of a rectangle is 3 feet longer than its width.
If the perimeter of the rectangle is 54 feet, find its length and width.
Answer:
Length = 15ft
Width = 12ft
Step-by-step explanation:
First, re-read the problem until you acknowledge it and can put it into your own words.
This is what I did:
Find the area of a rectangle by first finding the length and the width. Note that:
L = Length
W = Width
Find L and W
We will need formula:
P=2L+2W
A=LW
The length of a rectangle is 3 ft longer than its width :
L = 3 + W Equation [1]
"the perimeter of the rectangle is 30 ft" means
P = 54 Equation [2]
P = 54 = 2L + 2W
54 = 2(3+W) + 2W
54 = 6 + 2W + 2W
54 = 6 + 4W
48 + 4w
12 ft = w
L = 3 + W
L = 3 + 12
L = 15 ft
Area if needed
A = L*W
A = (12 ft)*(15 ft)
A = 180 sq ft

Step-by-step explanation:
Check photo for work
The 12 pounds of ground beef cost is $15.48.
What is unitary method ?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
According to the question
8 pounds of ground beef cost $10.32
i.e 8 pounds of ground beef = $10.32
1 pounds of ground beef = [tex]\frac{10.32}{8}[/tex]
1 pounds of ground beef = $1.29
Therefore,
12 pounds of ground beef = 1.29*12
12 pounds of ground beef = $15.48

find the area of a circle whose radius is 14cm
Answer:
Formula for area of circle;
A = π[tex]r^{2}[/tex]
Where 'π' represents pi(3.14 or 22/7), and 'r' stands for the radius which is being squared.
What we know:
Radius = 14cmPlug in what we know;
A = π[tex]r^{2}[/tex]
(For pi I'll be using 3.14 instead of 22/7)
A = 3.14(14^2) ← (The symbol ' ^ ' means to the power of.)
A = 3.14(196)
A = 615.44, 615.44 centimetres is the area of this circle.
Answer:
≈[tex]615.44cm^2[/tex]
Step-by-step explanation:
So the equation for area of circle.
[tex]\pi r^2\\\pi 14^2[/tex]
So 14^2, or 14 x 14 is 196.
Now you can either keep it in terms of pi, 196pi, or times it by pi.
[tex]196*pi\\196*3.14\\615.44[/tex]
So the answer would be around 615.44cm^2
