Answer:

x = -7

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

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

2.5x + 10 = x - 0.5

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

  1. Subtract <em>x </em>on both sides:                    1.5x + 10 = -0.5
  2. Subtract 10 on both sides:                  1.5x = -10.5
  3. Divide both sides by 1.5:                     x = -7

<u>Step 3: Check</u>

<em>Plug in x to verify it's a solution.</em>

  1. Substitute:                    2.5(-7) + 10 = -7 - 0.5
  2. Multiply:                        -17.5 + 10 = -7 - 0.5
  3. Add/Subtract:               -7.5 = -7.5

And we have our answer!

Choose the ratios for sin A and cos A.
Irina18 [472]

Answer: D


Step-by-step explanation: By using SOH for sin A, 'S' being sin, 'O' being opposite side of angle A and 'H' being the hypotenuse which is the longest part of the triangle you would find that 15 is opposite from Sin A and 17 the hypotenuse, 15/17.

For cos A you would use CAH, C= cos, A which is the adjacent of the triangle located next to angel A which is 8, and H= hypotenuse (also note that the hypotenuse never changes even if the angle may be different) CAH would be cos A = 8/17
