Answer:
C = 39
Step-by-step explanation:
From the question given above, the following data were obtained:
A = 2x + 108
B = x + 33
C =?
Next, we shall obtain an expression for C. This can be obtained as follow:
A + B + C = 180 (sum of angles in a triangle)
2x + 108 + x + 33 + C = 180
2x + x + 108 + 33 + C = 180
3x + 141 + C = 180
Make C the subject by rearranging
C = 180 – 141 – 3x
C = 39 – 3x
Next, we shall determine the value of x. This can be obtained as follow:
A = 2x + 108
B = x + 33
C = 39 – 3x
A + B + C = 180
2x + 108 + x + 33 + 39 – 3x = 180
2x + x – 3x + 108 + 33 + 39 = 180
3x – 3x + 180 = 180
3x – 3x = 180 – 180
3x – 3x = 0
x(3 – 3) = 0
x(0) = 0
x = 0
Finally, we shall determine C. This can be obtained as follow:
C = 39 – 3x
x = 0
C = 39 – 3(0)
C = 39 – 0
C = 39
is the relation a function?
Answer:
Yes, each x-value is paired with exactly one y-value (no more than that)
Domain: x = -2, x = 1, x = 4, x = 7
Range: y = -3, y = 5, y = 6
No, the inverse is not a function, the x value of 6 would be paired with two y values (-2 and 7)

The total cost of these 2 pens is 60p.
Work out the total cost of 5 of these pens.
Give your answer in pounds.
Answer:
£1.50
Step-by-step explanation:
If two pens equal 60p
do 2 x 2 = 4
4 pens equal £1.20
to get 1 pen do 60p divided by 2
which equals 30p
now add £1.20 and 30p

10. If ABCD is a parallelogram, find m
Answer: The angle C measures 120 degrees.
Step-by-step explanation:
For a polygon of n side, the sum of internal angle, in degrees is given by:
S = (n - 2) x 180
Parallelogram
4 sides, so
S = ( 4 - 2) * 180 = 360
Two pair of equal angles
B and D measure 60
A and C measure x. so
2ₓ + 2 * 60 = 360
2× = 240
× = 240/2
× = 120
The angle C measures 120 degrees
Hope this helps! :)
The measures of the exterior angles of a heptagon are xº, 2x°, 4x°, 6x°, 8x°, 9x°
and 10x°. Solve for x.
Answer:
the sum of exterior angle of a polygon is always 360 degree.
therefore,
xº+ 2x°+ 4x°+ 6x°+ 8x°+ 9x° +10x° = 360°
40x = 360°
x = 360/40 = 9
x = 9
The sum of the exterior angles of a polygon is 360 degrees, so the value of x is 9
The exterior angles of the polygon are given as:
xº, 2x°, 4x°, 6x°, 8x°, 9x° and 10x°
The exterior angles of a polygon add up to 360 degrees.
So, we have:
[tex]x\º+ 2x\°+ 4x\°+ 6x\°+ 8x\°+ 9x\° +10x\° = 360\°[/tex]
Evaluate like terms
[tex]40x\° = 360\°[/tex]
Divide both sides of the equation by 40
[tex]x\° = \frac{360\°}{40}[/tex]
Divide 360 by 40
[tex]x\° = 9[/tex]
Rewrite as:
[tex]x = 9\°[/tex]
Hence, the value of x is 9

Heather has a rectangular yard, she measures it and finds out it is 24 1/2 feet long by 12 4/5 feet wide. She wants to know how many square feet of sod she will need to cover her yard. How much did will she need and if each square inch of sod cost 65 cents how much will she pay to cover her yard?
Answer: $2,446.08
Step-by-step explanation:
Lets convert the length and width into decimal form so it's easier to understand.
24 1/2= 24.5
12 4/5= 12.8
Now we must multiply to get the area. 24.5x12. 8= 313. 6 ft
Each square inch costs .65 so we must multiply .65 by 12 to see how much a foot costs. 12x0.65= 7.8
Now that we know how much each foot cost lets multiply 313.6 by 7.8. 313.6x 7.8= $2446.08

Step-by-step explanation:
Determine the length of the line segment with the end points at (9, 6) and (-12, 6).
Answer:
Step-by-step explanation:
You are given two points whose y values are the same. There is no need to use the distance formula. The x values alone will give you the length of the line.
to get to the y axis you have to go 12 units to the right.
To get from the y axis to 9, you have to go 9 more units to the right.
The total is 9 + 12 = 21
If you insist to see this done with the formula, it would look like this.
d = sqrt( y2 - y1)^2 + (x2 - x1)^2 )
y2 = 6
y1 = 6
x2 = -12
x1 = 9
d = sqrt ( (6 - 6)^2 + (-12 - 9)^2 )
d = sqrt( 0 + ( -21 )^2 )
d = sqrt( 441)
d = 21 the same thing you got just be reasoning it out.
The first method works only if either both xs are the same or both ys are the same.

Answer: Each lemon costs $0.75 cents (seventy five cents)
Step-by-step explanation:
0.50 x 8 is the same as "half" of 8. This is $4. That is too low so.. 0.75 cents
6 ÷ 8 = 0.75
