The measures of the angles of a triangle are shown in the figure below. Solve for x.
(6x+20)
(7X-10)
105

Answers

Answer 1

Answer:

x = 5

Step-by-step explanation:

Angles in a  triangle = 180°

 (6x + 20) + (7x - 10) + 105 = 180°

 13x + 10 +105 = 180

  13x + 115 = 180

         -115 = -115      

   13x         = 65

    x = 65/13

     x = 5

Answers

Answer:

See answer below.

Step-by-step explanation:

1. Start at point (0,0), This point is where the x-y-axis meet.  Do not put a dot

   there because this is your starting point.

2.  Move to the left over to point -1 3/4 . This place is between -1 and -2, and

     closer to -2 because the point is -1 .75.  Remember this point is not on the

     graph.  

3.  Now move up from that point to 4.5 and put a dot at that place.  The point is in the Q II ,  to the left top.

Which equation represents a line which is parallel to the line y = -5/8x + 6?

A) 8x + 5y = 10
B) 8x - 5y = 15
C) 8y - 5x = -24
D) 5x + 8y = 32

Answers

Step-by-step explanation:

y = -5x/8 + 6

8y = 8 × (-5x/8 + 6)

8y = -5x + 42

5x + 8y = 42

5x + 8y = K, k element real

Option → D

The equation for parallel line is 5x + 8y = 32.

The correct option is (D).

What is slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

Given:

Equation: y = -5/8x + 6

Now, the parallel line to above equation must have the slope same as the given equation i.e., -5/8.

Then, writing the equation in slope intercept form

A) 8x + 5y = 10

5y= 10 - 8x

y= 10/5 - 8x/5

y= -8/5x + 2

B) 8x - 5y = 15

-5y= 15 - 8x

y= 8/5 x + 3

C) 8y - 5x = -24

8y= -24 + 5x

y= -24/8 +5/8x

y= +5/8x - 3

D) 5x + 8y = 32

8y= 32 -5x

y= -5/8x + 4

Hence, the equation for parallel line is 5x + 8y = 32.

Answer:

x = 12.633, -0.633

Step-by-step explanation:

x^2 -12x + 36 = 44

the underlined part is (x - 6) ^2

(x - 6)^2 = 44

(x - 6) = ± [tex]\sqrt{44}[/tex]  (both positive and negative)

(x - 6 ) = + 6.6332495807108

x = 12.6332495807108 = 12.633

(x - 6 ) = - 6.6332495807108

x = - 6.6332495807108 + 6

= -0.6332495807108 = -0.633

five more than one-third of a number is -2. Find the number

Answers

Answer:

x = -21

Step-by-step explanation:

Words To Algebra:

Words : Five more than one-third of a number = -2

Algebraic Equation: 5 + (1/3)x = -2

Isolate x:

5 + (1/3)x = -2      [tex]\longmapsto\\[/tex]    Subtract 5 from both sides

5 + (1/3)x - 5 = -2 - 5

(1/3)x = -7     [tex]\longmapsto\\[/tex]     Multiply All sides by 3

(1/3)x * 3 = -7 * 3

x = -21

Check:

5 + (1/3)-21 = -2

5 + -7 = -2

-2 = -2

The length of a rectangle is 4 units more than triple its width. If the perimeter is 64,
what is the length of the rectangle?

Answers

Answer: Length = 25, width = 7

Step-by-step explanation:

Let width be w, and length be 3w + 4.

Perimeter of a rectangle = 2l + 2w

                                 64  = 2(3w + 4) + 2w

                                 64  = 6w + 8 + 2w

                                 64  = 8w + 8    [subtract 8 from both side]

                                 56  = 8w          [Divide 8 from both side]

                                  w   = 7

Plug w in l, where l = 3w + 4 = 21 + 4 = 25
