Equality Properties

Step-by-step explanation:

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

4x - 8 = 16

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

  1. Add 8 to both sides:                    4x = 24
  2. Divide 4 on both sides:               x = 6

<u>Step 3: Check</u>

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

  1. Substitute in <em>x</em>:                   4(6) - 8 = 16
  2. Multiply:                              24 - 8 = 16
  3. Subtract:                             16 = 16

Here we see that 16 does indeed equal 16.

∴ x = 6 is the solution to the equation.

I NEED HELP ASAP!!!! PLEASE HELP!!!
IRISSAK [1]

Answer:

y= 2x-3  m=2 b= -3

Step-by-step explanation:

we distribute 2(x-2)

y-1 = 2(x-2)

y-1 = 2x-4

then add one to both sides

y-1= 2x -4

 +1       +1

since it is negative four and you are adding one it would be -3

y= 2x -3  that is your slope intercept form.

y= mx +b  so m=2 and b= -3

jasenka [17]
Answer: Use the formula: 2(pi)(r + 1) - 2(pi)r

In your problem, you didn't give any measurements to use, so we can't determine an exact answer. However, the given formula above would work. 

The first term calculates the extended length of rope. The second term calculates the original length of rope. All you need to do is subtract them.

Online, you can find the radius of the Earth if you need an exact value. 3,959 miles
