Answer:

x = 38/6

Step-by-step explanation:

x/5 - 2/3 = 3/2

3x - 2x5/3x2 = 3/2

3x-10/6 = 3/2

2(3x-10) = 3x6

6x-20 = 18

6x = 18+20

6x =38

x =38/6 or x = 6.33

The midpoint of segment ST is M(5,2). One endpoint is S(-1, -7). Find the coordinates of the other endpoint.
Tasya [4]

Answer:

The other endpoit has this cordinadetes (11, 11).

Step-by-step explanation:

Midpoint (MD) (Xm, Ym)

Xm = 5

Ym = 2

Xm of the Midpoint:    Xm = X1 + X2/ 2

Ym of the Midpoint:    Ym = Y1 + Y2/2

<em>We can say that S is (x1, y1), so x1 = -1 and y1 = -7</em>

Then:

Xm = -1 + x2/2

5= -1 + x2/2

10 = -1 + x2

x2 = 11

Also:

Ym = -7 + y2/2

2 = -7 + y2/2

4 = -7 + y2

11 = y2

An online store sells two types of speaker docks for smartphones. The higher-priced speaker dock sells for $170 and the lower-pr
Alenkinab [10]

The lower-priced speaker docks and higher-priced speaker docks is 9 and 36 respectively.

<h3>Algebra</h3>

  • Cost of higher-priced speaker = $170
  • Cost of lower-priced speaker = $80
  • Number of lower-priced speaker = 4x
  • Number of higher-priced speaker = x

Higher-priced speaker = 170 × x

= 170x

Lower-priced speaker = 80 × 4x

= 320x

Total sales = $4,410

170x + 320x = 4,410

490x = 4,410

divide both sides by 490

x = 4,410 / 490

x = 9

So,

Number of lower-priced speaker = 4x

= 4 × 9

= 36

Number of higher-priced speaker = x

= 9

Therefore, the lower-priced speaker docks and higher-priced speaker docks is 9 and 36 respectively.
