To convert a fraction to a percent, divide the numerator by the denominator, this should give you a decimal. To change it from decimal to a percent, multiply the decimal by 100. 

1. 4/5 = 0.8 = 0.8*100 = 80% 
2. 11/25 = 0.44 = 0.44*100 = 44%
3. 4/50 = 0.08 = 0.08*100 = 8%

Answer:

(-3, 4)

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right  

Equality Properties

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

<u>Algebra I</u>

  • Terms/Coefficients
  • Coordinates (x, y)
  • Solving systems of equation using substitution/elimination

Step-by-step explanation:

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

3y = -5x - 3

y = -x + 1

<u>Step 2: Rewrite Systems</u>

Equation y = -x + 1

  1. [Multiplication Property of Equality] Multiply everything by -3:                   -3y = 3x - 3

<u>Step 3: Redefine Systems</u>

3y = -5x - 3

-3y = 3x - 3

<u>Step 4: Solve for </u><em><u>x</u></em>

<em>Elimination</em>

  1. Combine 2 equations:                                                                                   0 = -2x - 6
  2. [Addition Property of Equality] Add 6 on both sides:                                  6 = -2x
  3. [Division Property of Equality] Divide -2 on both sides:                              -3 = x

<u>Step 5: Solve for </u><em><u>y</u></em>

  1. Define original equation:                                                                               y = -x + 1
  2. Substitute in <em>x</em>:                                                                                                y = -(-3) + 1
  3. Simplify:                                                                                                           y = 3 + 1
  4. Add:                                                                                                                 y = 4

A security alarm requires a four-digit code. The code can use the digits 0–9 and the digits cannot be repeated.
never [62]

Answer:

The answer is <em>C</em>

Explanation: Given:A security alarm requires a four-digit code. The code can use the digits 0–9 and the digits cannot be repeated.  

there is only 2 numbers which are greater than 7 i.e. 8 and 9. ∴ there is 2 possibility for first place.

For the remaining 3 digits there is 9 possibilities (including 1 which would left after choosing 1 from first place )

No of ways for the alarm code beginning with a number greater than 7= 2 P 1 x 9 P 3

<em>Total ways of code with 4 digits= 10 P 4.</em> Hope this helps :)

Theresa has $12 in nickels amd quarters if she has the same number of each kind of coin how many nickels and quarters does she h
Bogdan [553]

n=# of nickels

q=# of quarters

$12 is 1200 cents

5n+25q=1200

n=q

substitute q for n or n for q

5q+25q=1200

30q=1200

q=1200/30

q=40 quarters and therefore n=40 nickels

40 quarters is $10 and 40 nickels is $2, therefore you have $12

Hope this helps.
