Answer:

  1. 1
  2. - 9
  3. 13
  4. 15

Step-by-step explanation

- 7(6x-1)+x=36

  1. => 42x - 7 + x = 36
  2. => 43x - 7 = 36
  3. => 43x =  36 + 6 = 43
  4. => x = 43 / 43 = 1

- 11-2(8+3p)=7²

  1. => 11 - 16 - 6p = 7^2
  2. => 11 - 16 - 6p = 49
  3. => -5 - 6p = 49
  4. => -6p = 49 + 5 = 54
  5. => p = (54) / (-6) = - 9

-  1/4(5b+11)=19

  1. => (5/4)b +  (11/4) = 19
  2. => (5/4)b = 19 - (11/4) = 65 /4
  3. => b = (65/4) / (5/4) => (65/4) * (4/5) = 13

- 2/7(4m-18)=12

  1. => (8/7)m - (36/7) = 12
  2. => (8/7)m = 12 + (36/7) = 120/7
  3. => m = (120/7) / (8/7) = 120 /8 = 15

Dovator [93]

The height of the green pyramid constructed  by Natalie while playing with magnetic building tiles is 26.25 cm.

<h3>Volume of the orange pyramid</h3>

The volume of the orange pyramid is calculated as follows;

V = ¹/₃Ah

where;

  • A is the base area of the pyramid
  • h is the height of the pyramid

V = ¹/₃ x (7²) x 5

V  = ¹/₃ x (245 cm³)

<h3>Volume of the green pyramid</h3>

Voume = 21 x [¹/₃ x (245 cm³)]

Volume = 1,715 cm³

<h3>Height of the green pyramid</h3>

V = ¹/₃Ah

3V = Ah

h = 3V/A

h = (3 x 1715) / (14²)

h = 26.25 cm

Answer:

<em><u>A theater has </u></em><em><u>60 seats</u></em><em><u> in the first row, 68 seats in the second row, 76 seats in the third row,</u></em>

<em><u>and so on in the same i</u></em><em><u>ncreasing pattern</u></em><em><u>. If the theater has</u></em><em><u> 20 rows of seats, how many seats are in the theater?</u></em>

220 seats in the theater.

So if the increasing pattern is +8, and we need to determined how many seats there will be if there where 20 rows, then you would need to multiply.

1. 8 x 20 = 160

2. 160 + 60 = 220
