Can anyone help me with this ill mark brainliest:

Mathematics
1 answer:
nirvana33 [79]2 years ago
7 0

Answer:

Choice D:

Step-by-step explanation:

If we check them one by one...

Choice A is all correct, so we leave that there for now

Choice B's 3x12 is equal to 36, so therefore it's wrong

Choice C has the same mistake as Choice B - 3x12 is not equal to 32

Choice D is all correct, so therefore it is the answer


Though Choice A is also correct, the question asked for <u>all</u> of the different ways you can arrange the cars

So, therefore... the answer is A!

<u><em>Hope this helped!</em></u>

<u>Algebra I</u>

  • Terms/Coefficients
  • Coordinates (x, y)
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

6x - 5y = 15

x = y + 3

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

<em>Substitution</em>

  1. Substitute in <em>x</em>:                                                                                                  6(y + 3) - 5y = 15
  2. Distribute 6:                                                                                                    6y + 18 - 5y = 15
  3. Combine like terms:                                                                                        y + 18 = 15
  4. [Subtraction Property of Equality] Subtract 18 on both sides:                     y = -3

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

  1. Define original equation:                                                                               x = y + 3
  2. Substitute in <em>y</em>:                                                                                                   x = -3 + 3
  3. Add:                                                                                                                   x = 0
