Solve for X

Will give brainiest

Answer:

the third one

Step-by-step explanation:

have a great day :)

It is C

In problem C X is still being multiplied by the other variable y, and also it is still multiplying the 7 too, The other questions do not factor in the multiplication required meaning that the only answer that could be applied would be C.

Hope this helps and have a nice day.

For original triangle, perimeter is 60. The area is 120.

The dilated triangle, perimeter is 180. The area is 1080.

Step-by-step explanation:

24 times 3=72

10 times 3=30

26 times 3=78

72+30+78=180

Perimeter of diliated triangle

1/2btimesh=area

1/2 30 times 72=1080 square units

Perimeter of original triangle

24+10+26=60 units

1/2 10 times 24=120 square units

From the picture attached,

Measure of the base of the small right triangle = 10 units

Height of the triangle = 24 units

Measure of the Hypotenuse = 26 units

Since, Perimeter of the triangle = Sum of the measures of the sides of the triangle

Therefore, Perimeter = 10 + 24 + 26

                                   = 60 units

Area of the triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                 = [tex]\frac{1}{2}(10)(24)[/tex]

                                 = 120 units²

Given triangle is dilated by a scale factor of 3 to form the bigger triangle,

Scale factor = 3

Since, expression for the scale factor is given by,

Scale factor = [tex]\frac{\text{Dimension of the image}}{\text{Dimension of the original}}[/tex]

Therefore, length of the base of the dilated (bigger) triangle will be,

[tex]3=\frac{\text{Measure of the base of the original}}{10}[/tex]

Measure of the base of the original = 30 units

Height of the dilated triangle will be,

[tex]3=\frac{\text{Height of the dilated triangle}}{24}[/tex]

Height = 24 × 3

            = 72 cm

Hypotenuse of the dilated triangle will be,

[tex]3=\frac{\text{Hypotenuse of the dilated triangle}}{26}[/tex]

Hypotenuse = 78 cm

Now the perimeter of the dilated triangle = 30 + 72 + 78

                                                                     = 180 cm

Area of the dilated triangle = [tex]\frac{1}{2}(30)(72)[/tex]

                                             = 1080 cm²

Answer:

Step-by-step explanation:

m∠R = 180° - 110° [Linear pair of angles are supplementary]

m∠R = 70°

m∠S = 45° [Vertically opposite angles]

By triangle sum theorem,

m∠P + m∠R + m∠S = 180°

m∠P + 70° + 45° = 180°

m∠P = 180 -115

        = 65°

Therefore, m∠A = m∠P = 65° [Vertically opposite angles]

By triangle sum theorem,

m∠B + m∠S + m∠T = 180°

m∠B + 45° + 65° = 180°

[m∠T = 65°. Since, ∠P and ∠T are corresponding angles]

m∠B = 180° - 110° = 70°

m∠C + m∠B = 180° [Linear pair of angles are supplementary]

m∠C = 180° - 70° = 110°

m∠D + m∠T = 180° [Linear pair of angles are supplementary]

m∠D + 65° = 180°

m∠D = 115°

Answer:

43/18

Step-by-step explanation:

Answer:

56/19

Step-by-step explanation:

I'll approach this using Substitution. Since 3X = 2Y, we know that 1.5X = 1Y. We can plug that into the first equation, which gives us...

2X + 5(1.5X) = 8

2X + 7.5X = 8

9.5X = 8

19X = 16

X = 16/19

While this is not 'pretty', it does match up with how most of the answers are written (four of the answers involve "nineteenths"). With this value of X, we can solve for Y...

3X = 2Y

3(16/19) = 2Y

48/19 = 2Y

24/19 = Y

With the value of X and the value of Y, we can answer the question that's asked:

2X + Y = ?

2(16/19) + 24/19 =

32/19 + 24/19 =

56/19

Final Answer: 56/19

Answer:

[tex]x = - 1[/tex]

[tex]y = - 2[/tex]

Step-by-step explanation:

[tex]3x + 2y = - 7[/tex]

[tex]2x - 5y = 8[/tex]

Apply elimination method. Let multiply the bottom equation by -3/2.

[tex]2 \times - \frac{3}{2} x = - 3[/tex]

[tex] - 5 \times - \frac{3}{2} = 7.5[/tex]

[tex]8 \times - \frac{3}{2} = - 12[/tex]

Substitute new equation and add it to the top equation

[tex]3x + 2y = - 7[/tex]

[tex] - 3x + 7.5y = - 12[/tex]

[tex]9.5y = - 19[/tex]

[tex]y = - 2[/tex]

Now plug -2 for y into any equation and solve for x.

[tex]3x + 2( - 2) = - 7[/tex]

[tex]3x - 4 = - 7[/tex]

[tex]3x = - 3[/tex]

Answer:

Step-by-step explanation:

either 1 foot or 33 ;-;

The value 5.1 feet long is a string reaching from the top of a 12-ft pole to a point on the ground that is 11 ft from the base of the pole.

In a right-angled triangle, the square of the hypotenuse side is equal to the sum of the squares of the other two sides, according to Pythagoras's Theorem.

Given:

A string reaching from the top of a 12-ft pole to a point on the ground that is 11 ft from the base of the pole.

Let the value is C.

The Pythagoras' theorem,

C² = (11)² + (12)²

C² = 121 + 144

C² = 265

C = 5.1 feet.

Therefore, the value is 5.1 feet.

Step-by-step explanation:

20000-578 to solve the problem

A percentage is essentially a fraction, but lazily written. Think of a percent as 25/100, or 0.25.

Now multiply the two.

0.25x5/8.

We need to convert 5/8 to a decimal, which is 0.625.

0.25x0.625=0.15625.

Now convert the decimal to a fraction, which is 5/32.

Answer:

Step-by-step explanation:

General form of circle: (x - h)² +  (y- k)² = r²

r - > radius and h ,k are the coordinates of the center.

5) (x - 5)² +  (y- 1)² = 64 = 8²

radius: 8 ;  Center (5 , 1)

6) (x + 7)² +  (y- 2k)² = 324 = 18²

Center = ( -7 , 2) ;  radius = 18 ;  diameter = 18 *2 = 36

7) (x )² +  (y + 10)² = 42.25 = 6.5²

Center = (0 , - 10);  radius = 6.5 ;  diameter = 6.5*2 = 13

8) (x - 6)² +  (y +  1)² = 80 =  (4√5)²

Center =(6, -1) ; radius = 4√5
