18/13=3/4x<br> what does x equal?
sveta [45]

Answer:

x = 24/13

General Formulas and Concepts:

<u>Pre-Alg</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

18/13 = 3/4x

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Divide both sides by 3/4:          x = 24/13

<u>Step 3: Check</u>

<em>Plug in x to verify it's a solution.</em>

  1. Substitute:                    18/13 = 3/4(24/13)
  2. Multiply:                        18/13 = 18/13

Can someone please help me
Natalija [7]
ANSWER: $84

EXPLANATION:

We need to know the surface area of the room with the specified dimensions.

A = 2(wl + hl + hw)

w = 12
h = 8
l = 16

A = 2( (12 * 16) + (8 * 16) + (12 * 8) )

A = 2(192 + 128 + 96)

A = 2(416)

A = 832 square feet


832 / 150 = 5.546666666666667

(Round that up to the next whole number)
