Distributive property means that we can take factor in from of parenthesis.
2l+2w=2(l+w)
The number is not changed, because factor can be easily multiplied by every argument in front of parenthesis.

You can do 21+(2*w) because 2w is equal to 2*w

What is the answer to<br> 7×9-8+11-6[5+2(-3)]
Radda [10]
It equals 72. If you have a problem like this again first start with the brackets, and the parentheses inside the brackets (if there is any). Then move onto the others outside the brackets like other parentheses (if there is any)

The formula for the volume of a cone is V=1/3 pi r2h the radius r of the cone may be expressed as
Naily [24]

r = √(3V/πh)

multiply both sides by 3 to eliminate the fraction

πr²h = 3V ( divide both sides by πh )

r² = 3V/ πh ( take the square root of both sides )

r = √(3V/πh)

Answer:

y=1.44

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define</u>

<u />\frac{4.5}{y} =\frac{12.5}{4}<u />

<u />

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

  1. Cross-multiply:                    4(4.5) = 12.5y
  2. Multiply:                               18 = 12.5y
  3. Isolate <em>y</em>:                              1.44 = y
  4. Rewrite:                               y=1.44

<u>Step 3: Check</u>

<em>Plug in y to verify it's a solution.</em>

  1. Substitute:                    \frac{4.5}{1.44} =\frac{12.5}{4}
  2. Divide:                          3.125=3.125

Here, we see that 3.125 does indeed equal 3.125. ∴ y = 1.44 is a solution of the equation.
