Answer:

a < -30/31

General Formulas and Concepts:

Order of Operations: BPEMDAS

  2. Parenthesis
  3. Exponents
  4. Multiplication

  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

Step-by-step explanation:

<u>Step 1: Define</u>

7a + 42 + 8 < -10 + 9a - 64a

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

  1. Combine like terms (a):                                                                                    7a + 42 + 8 < -10 - 55a
  2. Combine like terms:                                                                                         7a + 50 < -10 - 55a
  3. [Addition Property of Equality] Add 55a on both sides:                                62a + 50 < -10
  4. [Subtraction Property of Equality] Subtract 50 on both sides:                      62a < -60
  5. [Division Property of Equality] Divide 62 on both sides:                               a < -30/31

Here we see any number <em>a</em> less than -30/31 would work as a solution to the inequality.

Monica is a lawyer who earns $8,322.65 every month. She spends $830.98 on rent, $210.36 on food, and $120.45 on gas every month.
dolphi86 [110]

Answer:

Money left from her earning after expenses is $ 7160.86

Step-by-step explanation:

Money earned by Monica every month = $ 8322.65

Money spend on rent = $ 830.98

Money spend on food = $ 210.36

Money spend on gas every month = $ 120.45

Money left from her earning = 8322.65 - ( 830.98 + 210.36 + 120.45 )

                                              = 8322.65 - 1161.79

                                              = $ 7160.86
