For this case, we propose a system of two equations with two unknowns.

Let:

x: Represents the number of children's tickets

y: Represents the number of adult tickets

5.20x + 8.60y = 931.20\\x + y = 132

So, we clear x from the second equation:

x = 132-y

We replace in the first one.

5.20 (132-y) + 8.60y = 931.20\\686.4-5.20y + 8.60y = 931.20\\-5.20y + 8.60y = 931.20-686.4\\3.4y = 244.8\\y = \frac {244.8} {3.4}\\y = 72

<em>72 adult tickets were sold. </em>

x = 132-y\\x = 132-72\\x = 60

<em>60 tickets for children were sold </em>

Answer:

60 tickets for children

72 adult tickets

Answer:

60 child tickets and 72 adult tickets

Step-by-step explanation:

Let x denote the number of child tickets sold and y the number of adult tickets sold. The problem involves solving the following system of linear equations; x+y=132 and 5.2x+8.6y=931.2. Using technology to solve this simultaneous equation yields; x= 60, y =72

Answer:

  • 12. x = 6, side = 83
  • 13. x = 18, side = 29
  • 14. x = 11, sides = 74, 74 and 37
  • 15. x = 23, sides = 95, 95 and 108

Step-by-step explanation:

<em>11 is incomplete, can't solve</em>

<u>The triangle is equilateral, so all sides are equal, using one pair to find x:</u>

  • 13x + 5 = 17x - 19
  • 17x - 13x = 5 + 19
  • 4x = 24
  • x = 6

<u>Each side is:</u>

  • 13*6 + 5 = 78 + 5 = 83

13.

<u>Sides are equal as triangle is equilateral</u>

  • QR = 2x - 7
  • RS = 5x - 61
  • QS = x + 11

<u>Finding x by comparing two sides</u>

  • 2x - 7 = 5x - 61
  • 5x - 2x = 61 - 7
  • 3x = 54
  • x = 18

<u>Sides are equal</u>

  • 18 + 11 = 29

14.

<u>Equal sides of isosceles triangle:</u>

  • CD = DE
  • 9x - 25 = 6x + 8
  • 9x - 6x = 8 + 25
  • 3x = 33
  • x = 11

<u>Sides are</u>

  • CD = DE = 9*11 - 25 = 99 - 25 = 74
  • CE = 10*11 - 73 = 110 - 73 = 37

15.

<u>Equal sides of isosceles triangle WXY, WX = WY</u>

  • WX = 4x + 3
  • WY = 7x - 66
  • XY = 5x - 7
  • 4x + 3 = 7x - 66
  • 7x - 4x = 3 + 66
  • 3x = 69
  • x = 23

<u>Sides are:</u>

  • WX=WY = 4*23 + 3 = 95
  • XY = 5*23 - 7 = 108

Find the length of the third side to the nearest tenth.<br> 5<br> 1
adelina 88 [10]

Answer:

square root of 26 (sorry couldn't get the symbol)

Step-by-step explanation:

C^2 = A^2 + B^2 (Pythagoras Theorem)

C^2 = 5^2 + 1^2

C^2 = 26

take square root of both sides

C =

\sqrt{26}

Can someone help with this?
Lana71 [14]

Answer:

72.1 cm

Step-by-step explanation:

The arc length formula is s = rФ, where Ф is the central angle and is in radians (not degrees).

Here we convert 140° to radians:  140°(π/180°) = 2.44 radians.

Then the desired arc length is s = rФ = (29.5 cm)(2.44 radians) = 72.1 cm
