Well, let's first find our rate of bags to meters.
If 12 bags of plaster covers 54m^2, then we need to divide 54 by 12 to figure out how many meters 1 bag of plaster covers. We will then use that rate and divide 36 by it in order to solve for how many bags of plaster is required.

54 / 12 = 4.5.
This means each bag of plaster covers 4.5m^2.

Divide 36 by 4.5;
36 / 4.5 = 8.
This means that we will need 8 bags of plaster to cover 36m^2.

I hope this helps!

  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right<u> </u>

<u>Algebra I</u>

  • Reading a coordinate plane
  • Coordinates (x, y)

<u>Algebra Ii</u>

  • Distance Formula: \displaystyle d = \sqrt{(x_2 - x_1)^2+(y_2 - y_1)^2}

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Find endpoints from graph</em>

Point (-3, -3)

Point (4, 2)

<u>Step 2: Find distance </u><em><u>d</u></em>

Simply plug in the 2 coordinates into the distance formula to find distance <em>d</em>

  1. Substitute in points [Distance Formula]:                                                         \displaystyle d = \sqrt{(4- -3)^2+(2- -3)^2}
  2. [√Radical] (Parenthesis) Subtract:                                                                    \displaystyle d = \sqrt{7^2+5^2}
  3. [√Radical] Evaluate exponents:                                                                       \displaystyle d = \sqrt{49+25}
  4. [√Radical] Add:                                                                                                  \displaystyle d = \sqrt{74}
