Circumference Formula: C = 2πr

  • <em>r</em> is radius

Step-by-step explanation:

<u>Step 1: Define</u>

[Circle] Radius <em>r</em> = 4 in

<u>Step 2: Find Circumference</u>

  1. Substitute in <em>r</em> [Circumference Formula]:                                                        C = 2π(4 in)
  2. [Circumference] Multiply:                                                                                 C = 8π in
  3. [Circumference] Substitute in π:                                                                      C = 8(3.14) in
  4. [Circumference] Multiply:                                                                                 C = 25.12 in
  5. [Circumference] Round:                                                                                   C ≈ 25 in

Solve the system of linear equations by substitution. <br> x + 4y = 6 <br> x - y = 1
bulgar [2K]

9514 1404 393

Answer:

  (x, y) = (2, 1)

Step-by-step explanation:

Use the second equation to write an expression for x:

  x = 1 +y

Substitute that into the first equation:

  (1 +y) +4y = 6

  5y = 5 . . . . . . . . subtract 1, collect terms

  y = 1 . . . . . . . divide by 5

  x = 1 +1 = 2 . . . use the expression for x to find x from y

The solution is (x, y) = (2, 1).
