Answer:

$367.38 is the cost to stain the entire deck.

Step-by-step explanation:

Here is what you need to know beforehand:

<em>Diameter</em> is <u>a line</u> that goes <u>through a circle</u>. <em>Radius</em> is <u>a line </u>that goes from <u>the edge of the circle all the way to the center</u>/<u>a line </u>that goes <u>halfway through the circle</u>.

--------------------------------------------------------------------------------------------------------------

<u>First, find the area of the circle. Here is the formula:</u>

Area = 3.14 (Pi) x r²

Since radius is half of the diameter (as explained above), you'll need to divide the diameter in half: 12m/2 = 6m

So the formula will look like this:

Area = 3.14 x 6²

<u>Then, you just do the math:</u>

Area = 3.14 x 6²

Area = 3.14 x 36

Area = 113.04

The goal of the problem is to find the amount of money Emma needs. <u>Finally, all you need to do is multiply the amount it cost to stain per square meter by the total area of the deck:</u>

Answer = 113.04 x 3.25

Answer = 367.38

$367.38 is the cost to stain the entire deck.

Answer:

x=1/15 y = -4 1/3

Step-by-step explanation:

First combine like terms.

-3y = 13

y= -13/3

y= -4 1/3

Substitute for y in next equation

-4 1/3 = 5x - 4

5x = 4 1/3 - 4

5x = 4 1/3 - 4

5x = 1/3

x = 1/3 divided by 5

Since fractions can't be divided, multiply by the inverse

x = 1/3 times 1/5 = 1/15

Which method would be the simplest way to solve the system?
Lunna [17]
It would be elimination (C) because 7x and -7x can be eliminated into 0.

  7x + 5y = 19
  -7x - 2y = -16
          3y = 3
           3     3
            y = 1
  7x + 5y = 19
7(1) + 5y = 19
    7 + 5y = 19
  - 7            - 7
          5y = 12
           5      5
           y = 2.4
    (x, y) = (1, 2.4)
