One angle of a triangle measures 65°. The other two angles are in a ratio of 3:20. What are the measures of those two angles?
Nataly_w [17]

Answer:

15° and 100°

Step-by-step explanation:

65 + 3x + 20x = 180

23x = 115

x = 5

3 × 5 = 15, 20 × 5 = 100. So the other two angles measure 15° and 100°.

3m - 3(m+8) &gt; 3m<br><br><br> (Teacher didn't go over this hopefully I can get an explanation)
zhuklara [117]
Alrighty!

*Note the ">" sign is similar to the "=" sign.

3m - 3(3m + 8) > 3m
3m - 6m + 24 > 3m (distribute)
-3m + 24 > 3m (combine like terms)
24 > 6m (Compute/simplify)
8 > m

Makes sense?

Which of the following is the solution to the system of linear equations<br> x=2y + 5 x/3-y=4/3
Alex73 [517]

Answer:

(7, 1)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

x = 2y + 5

x/3 - y = 4/3

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

  1. Substitute:                              (2y + 5)/3 - y = 4/3
  2. Multiply 3 on both sides:       2y + 5 - 3y = 4
  3. Combine like terms:               -y + 5 = 4
  4. Isolate <em>y</em> term:                         -y = -1
  5. Isolate <em>y</em>:                                  y = 1

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

  1. Define:                    x = 2y + 5
  2. Substitute:              x = 2(1) + 5
  3. Multiply:                  x = 2 + 5
  4. Add:                        x = 7

And we have our final answer!
