Equality Properties

Step-by-step explanation:

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

186 = 6(3n + 7)

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

  1. Divide 6 on both sides:                    31 = 3n + 7
  2. Isolate <em>n</em> term:                                   24 = 3n
  3. Isolate <em>n</em>:                                            8 = n
  4. Rewrite:                                             n = 8

<u>Step 3: Check</u>

<em>Plug in n into the original equation to verify it's a solution.</em>

  1. Substitute in <em>n</em>:                    186 = 6(3(8) + 7)
  2. Multiply:                               186 = 6(24 + 7)
  3. Add:                                     186 = 6(31)
  4. Multiply:                               186 = 186

Here we see that 186 does indeed equal 186.

∴ n = 8 is the solution to the equation.

Jason Runs 100 yards in 15 seconds How Many feet can jason run in 15 seconds
SpyIntel [72]

Answer:

He can run 20 ft in 15 seconds

Step-by-step explanation:

we need to change yards to ft

3ft = 1yd

100 yds * 3ft/1yd = 300 ft

distance = rate * time

300 ft = rate * 15 seconds

divide by 15 seconds on both sides

300 ft/15 seconds = rate

20 ft/sec

He can run 20 ft in 15 seconds
