Answer:

x - y = 9

x = 9 + y (equation 1)

Their sum is 46

x + y =46

(9 + y) + y = 46

9 + 2y = 46

2y = 46 - 9

2y = 37

y = 37/2

y = 18.5 ( one number)

second number =

place the value of y in equation 1

x = 9 + 18.5

x = 27.5

The two numbers are 18.5 and 27.5

X + y = 46 x=46-y

x - y= 9

46 - y - y= 9

46 - 2y = 9

Y=37/2

2. Find the value of x and y rounded to the nearest tenth.
SVETLANKA909090 [29]

Using relations in a right triangle, it is found that the values of x and y are given by: x = 24, y = 46.4, given by option a.

<h3>What are the relations in a right triangle?</h3>

The relations in a right triangle are given as follows:

  • The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
  • The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
  • The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.

First, we start with the vertical line h that divides y, that is <u>opposite to an angle of 30º, with hypotenuse 34</u>, hence:

sin(30º) = h/34

0.5 = h/34

h = 17.

Then, h is opposite to an angle of 45º, while the hypotenuse is x, hence:

\sin{45^\circ} = \frac{17}{x}

x = \frac{17}{\sin{45^\circ}}

x = 24.

y is divided into two segments.

  • The first is the adjacent to the angle of 30º, while the hypotenuse is 34.
  • The second is adjacent to the angle of 45º, while the hypotenuse is 24.

Then:

\cos{30^\circ} = \frac{y_1}{34}

y_1 = 34\cos{30^\circ} = 29.4

\cos{45^\circ} = \frac{y_2}{24}

y_2 = 24\cos{45^\circ} = 17

Then, the value of y is given by:

y = y_1 + y_2 = 29.4 + 17 = 46.4.

Maru [420]

Answer:

For radio = $40.43

Television =  $444.73

Player =  $364.73

Step-by-step explanation:

The computation of the each device cost is shown below:

let us assume the following things

radio be x

television x + 10x

player x + 10x - $80

Now the equation is

x + x + 10x + x + 10x - $80 = $850

3x + 20x - $80 = $850

23x = $930

x = $40.43

For radio = $40.43

Television = $40.43 + 10(40.43)

= $40.43 + $404.3

= $444.73

and, the player would be

= $444.73 - $80

= $364.73

Please help me on this question
labwork [276]

Answer:

y = 4

Step-by-step explanation:

Make equal ratios. y  10               4

                                              =  

                               x   22.5          9

If you divide 10 and 22.5, you get 0.44 repeating. If you divide 4 and 9, you will also get 0.44 repeating.
