Answers

Answer 1

Answer:

(4,-1)

Step-by-step explanation:

You can solve this system of equations in a couple of different ways, but I'm going to use the elimination method. If you're solving a system of equations using elimination, you want to have one variable cancel out. In this case, we don't have to change anything because -3y and 3y will already cancel out if we add the two equations together. You can both add or subtract, but it's easiest to add in this case. The equation will be set up like this: 2x-3y=11

+ 7x+3y=25

--------------

After you add them together, you should get 9x=36, which you can solve by dividing both sides by 9. Then, you'll get x=4. This is your x-coordinate. Next, you want to get your y-coordinate, so you can substitute 4 into one of the two equations for x and solve for y. This will get you -1 for y. I'd also recommend checking your answer. Hope this was helpful! :)

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?

Answers

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

Determine the length of the line segment with the end points at (9, 6) and (-12, 6).

Answers

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:

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

Answers

Since angle A and B are interior angles, we can set them equal to each other. So then we can solve for x and plug x in for B.
1) 8x + 78 = 2x + 114
2) 8x - 2x = 114 - 78
3) 6x = 36
4) 6x / 6 = 36 / 6
5) x = 6
Now we can plug in x to equation b
1) 2(6) +114
2) angle b = 126

The measures of the exterior angles of a heptagon are xº, 2x°, 4x°, 6x°, 8x°, 9x°
and 10x°. Solve for x.

Answers

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
