Answer:

A 13.75

Step-by-step explanation:

because you said the you 1 ponit for every right ans and -0.25 for incorret ans so 15 right ans would give you 15 ponits and 5 incorret ans would give you -1.25  so i add up  

15+-1.25=13.75 or 55/4

-36x - 24 ≤ -6(5x + 12)​
puteri [66]

Answer:

x ≥ 8

General Formulas and Concepts:

<u>Pre-Alg</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

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

-36x - 24 ≤ -6(5x + 12)

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

  1. Distribute -6:                         -36x - 24 ≤ -30x - 72
  2. Add 36 on both sides:         -24 ≤ 6x - 72
  3. Add 72 on both sides:          48 ≤ 6x
  4. Divide both sides by 6:         8 ≤ x
  5. Rewrite:                                  x ≥ 8

Here we see that any number <em>x</em> greater than or equal to 8 would work as a solution.
