Answer:

y = 54

General Formulas and Concepts:

<u>Pre-Algebra </u>

Order of Operations: BPEMDAS

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

<u>Algebra I </u>

  • Equality Properties

<u>Geometry </u>

  • Congruency
  • All angles in a triangle add up to 180°

Step-by-step explanation:

<u> Step 1: Define</u>

3(x + 7)° = 63°

3(x + 7)° + 63° + y° = 180°

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

  1. Divide 3 on both sides:                    x + 7 = 21
  2. Subtract 7 on both sides:                 x = 14

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Substitute in <em>x</em>:                    3(14 + 7) + 63 + y = 180
  2. (Parenthesis) Add:              3(21) + 63 + y = 180
  3. Multiply:                               63 + 63 + y = 180
  4. Combine like terms:           y + 126 = 180
  5. Isolate <em>y</em>:                              y = 54

sasho [114]

Answer:

r

Step-by-step explanation:

<u>Function Modeling</u>

The problem gives us the following conditions: The bottom of Ignacio's desktop is 74.5 cm from the floor, and the top of his legs is 49.3 cm from the floor. We know the chair where he's sitting at has a knob that raises the legs 4.8 cm per clockwise rotation r. This means that the total distance the legs are raised for r rotations is 4.8r. The total distance of his legs from the floor is then:

49.3+4.8r

This distance cannot reach or exceed 74.5 cm, thus

49.3+4.8r

Solving for r

\displaystyle r

Or, equivalently

\boxed{r
