Answer:

a = 12

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition

  • Left to Right  

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality<u> </u>

<u>Trigonometry</u>

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²

  • a is a leg
  • b is another leg
  • c is the hypotenuse<u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify variables</em>

<em>a</em> = <em>a</em>

<em>b</em> = 9

<em>c</em> = 15

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

  1. Substitute in variables [Pythagorean Theorem]:                                            a² + 9² = 15²
  2. Evaluate exponents:                                                                                         a² + 81 = 225
  3. [Subtraction Property of Equality] Subtract 81 on both sides:                       a² = 144
  4. [Equality Property] Square root both sides:                                                    a = 12

Answer:

5

Step-by-step explanation:

Given: 5^3– 10^2 = X(8 – 2) + 2X – 3X

Solving the equation to find the value of x.

⇒ 5^{3} -10^{2} = x(8-2)+2x-3x

Using the distributive property of multiplication, multiplying x with 8 and -2

⇒125-100= 8x-2x+2x-3x

cancelling out -2x and 2x

⇒ 25= 8x-3x

⇒ 25= 5x

Multiplying both side by 5

⇒ x= \frac{25}{5}

∴ x= 5

Hence, the value of unknown is 5.

Solve for n.<br><br> 60 = n/3 + 52
aniked [119]
60= n/3 + 52
-52. -52
8= n/3
You then take 3/1 times 8 therefore you leave n by itself
n = 24

Need some help Appreciate any help Take a look at the screenshot
malfutka [58]

Answer:

y = -1/2x+2

Step-by-step explanation:

Two points on the line are (0,2) and (4,0)

We can find the slope

m = (y2-y1)/(x2-x1)

   = (0-2)/(4 -0)

   = -2/4

    - 1/2

We know the y intercept is 2 since it crosses the y axis at 2

The slope intercept form is

y = mx+b where m is the slope and b is  the y intercept

y = -1/2x+2
