Find the solution of this system of equations. Separate the x- and y-values with a comma. x= -8+y -3x – 3y = 24
Answers
Answer:
(-8,0)
Step-by-step explanation:
X=-8+y equation 1
-3x-3y=24 equation 2
-3(-8+y)-3y=24 sub x value in equation into x value of equation 2
24-3y-3y=24
-6y=0
y=0
solve for x
x=-8+y
x=-8+0
x=-8
check answer:
-3x-3y=24
-3(-8)-3(-0)=24
24-0=24
24=24
In order, range, median, mode and mean. Round the mean to the nearest tenth.
PLS HELP ASAP
Answers
Answer:
Range: 40
Median: 55
Mode: 72
Mean: 54.6
Step-by-step explanation:
First, let's put all of the numbers down.
32, 34, 35, 40, 41, 54, 54, 56, 63, 69, 70, 72, 72, 72
Now, to find the range, subtract 72 - 32 = 40
To find the median, find the number in the middle
32, 34, 35, 40, 41, 54, 54, 56, 63, 69, 70, 72, 72, 72
Because there are an even amount of numbers we will find the mean of those two numbers which would be 55.
To find the mode, look for the number that appears the most.
32, 34, 35, 40, 41, 54, 54, 56, 63, 69, 70, 72, 72, 72
To find the mean, add everything up.
32, + 34, + 35, + 40, + 41, + 54, + 54, + 56, + 63, + 69, + 70, + 72, + 72, + 72 = 764
Then, divide. 764 ÷ 14 = 54.6 when rounded to the nearest tenth.
I hope that this helps, and you have a great day! :)

Is (8, 3) a solution to the system?
- x + 4y = 4
- x + 3y = 1
Answers
Answer:
Step-by-step explanation:
You can either substitute (8, 3) into both equations as a test, or you can find the solution yourself.
Rewrite
- x + 4y = 4
- x + 3y = 1
as
- x + 4y = 4
+ x - 3y = -1
and combine like terms. The result is y = 3. Then -x + 4(3) = 4, or 8 = x.
Yes, (8, 3) is a solution of this SYSTEM.

A rectangular room is 7 times as long as it's wide and it's perimeter is 64metres. Find the dimension of the room.
Answers
Answer:
Length = 28 meters Width = 4 metersStep-by-step explanation:
Assume the width of the rectangle is x. That means that the length of the rectangle is 7x which is 7 times as long as it is wide.
Perimeter of a rectangle:
= Length + length + Width + Width
Therefore:
7x + 7x + x + x = 64
16x = 64
x = 64/16
x = 4 meters
Length is 7 times as long:
= 4 * 7
= 28 meters

Step-by-step explanation:
1: 7x+3=9x-33
2x=36
x=18
2: 16x+(6x=26)=180
22x=154
x=7
3: (10x-17)-(2x-3)=90
8x-14=104
x=12
Answer and Step-by-step explanation:
1.
7x + 3 = 9x - 33
Subtract 7x from both sides, and add 33 to both sides of the equation.
36 = 2x
Divide both sides by 2.
x = 18
2.
6x + 26 + 16x = 180
Combine like terms.
22x + 26 = 180
Subtract 26 from both sides of the equation.
22x = 154
Divide 22 from both sides of the equation.
x = 7
3.
90 + 2x - 3 = 10x - 17
Add 17 to both sides of the equation, subtract 2x from both sides of the equation and combine like terms.
104 = 8x
Divide 8 from both sides of the equation.
x = 13

Answers
Answer:
The number is -3.
Step-by-step explanation:
Set up an equation:
Variable n = number
12 + 7n = n - 6
Assuming the question is solve for n, isolate the variable:
Subtract n from both sides:
12 + 6n = -6
Subtract 12 from both sides:
6n = -18
Divide by 6 on both sides:
n = -3
Check your work:
12 + 7(-3) = -3 - 6
12 - 21 = -3 - 6
-9 = -9
Correct
12+6n=-6
6n=-18

Answers
Answer:
52
Step-by-step explanation:
Total Number of students :
Stage 3 : 380
Stage 4 : 240
Stage 5 : 110
Total = (380 + 240 + 110) = 730
Number of samples required = 100
Number of key stage 3 students required :
(Key stage 3 / total) * number of samples
(380 / 730) * 100
= 0.5205479 * 100
= 52.0547
= 52
Mean: also called the average. The mean is found by adding all the numbers in the set and then dividing that total by the number of values in the set Median: is the middle value when the numbers are in order from least and greatest.
