Equality Properties

Step-by-step explanation:

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

-4(x + 2) = 4(2 - 2x)

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

  1. Divide -4 on both sides:                    -(x + 2) = 2 - 2x
  2. Distribute negative:                           -x - 2 = 2 - 2x
  3. Add 2x on both sides:                       x - 2 = 2
  4. Add 2 on both sides:                         x = 4

<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(4 + 2) = 4(2 - 2(4))
  2. Multiply:                               -4(4 + 2) = 4(2 - 8)
  3. Add/Subtract:                      -4(6) = 4(-6)
  4. Multiply:                               -24 = -24

Here we see that -24 does equal -24.

∴ x = 4 is the solution to the equation.

Dominic rides his bike at a rate of 4 min per mile
taurus [48]

Answer:

Dominic can ride a mile every 4 minutes so if total miles is represented by m, then the solution for how many minutes he's riding for a specific amount of time would be 4m (4 x m). For example, if you want to find out how many minutes it would take to ride 1 mile, substitute m for 1. It would be 4 x 1 = 4 so it takes a total of 4 minutes. If you want to find out how many minutes it took to ride 6 miles, substitute m for 6. It would be 4 x 6 = 24 so it would take a total of 24 minutes to ride 6 miles. If you want to find out how many minutes it took to ride 12 miles, substitute m for 12. It would be 4 x 12 = 48 so it would take a total of 48 minutes to ride 12 miles. I think you gave a lack of information so your question is incomplete but I hope this is applicable and helps anyways!

1. if we add something in x then it will also add up in value of y

2.  x by 5 times then y value increases by 3*5 = 15 times

3.  if x is added with 5 then y value increases by 8.

<h3>What is Algebra?</h3>

Algebra is the part of mathematics that helps represent problems or situations in the form of mathematical expressions.

As, per the first part

y=x

So, if we add something in x then it will also add up in value of x.

In second part,

y=3x

If x by 5 times then y value increases by 3*5 = 15 times

In third part, if x is added with 5 then y value increases by 8.

Which value of a would make the expression 5 1/3 divided by 4/a equivalent to a whole number?
Leya [2.2K]

9514 1404 393

Answer:

  a = any positive multiple of 3

Step-by-step explanation:

You want ...

  (5 1/3)/(4/a) = whole number

  (16/3)·(a/4) = whole number

  (4a/3) = whole number

This will be the case for a = 3n, for any positive integer n.
