Answer:
x = infinite amount of solutions
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
3(x + 10) + 6 = 3(x + 12)
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute 3: 3x + 30 + 6 = 3x + 36
- Combine like terms: 3x + 36 = 3x + 36
- Subtract 36 on both sides: 3x = 3x
- Divide 3 on both sides: x = x
Here we see that <em>x</em> does indeed equal <em>x</em>. We can plug in any number <em>x</em> and it would render the equation true.
∴ x = infinite amount of solutions

Answer:
round to 1
Step-by-step explanation:
it is closest to 1 so it wouldnt make sense to round to a number farther away
The valid probability distributions are the ones in options C and D.
<h3>
Which of the following are valid probability distributions?</h3>
For discrete random variables with probabilities p₁, p₂, ..., pₙ, there are two rules:
- All of these probabilities are numbers between 0 and 1.
- p₁ + p₂ + ... + pₙ = 1.
So, for the first rule we can discard the first option, where we have negative probabilities.
To check the other 4 options, just add the probabilities and see if the addition gives 1.
The options that add up to 1 are C and D, so these two are the correct options.
D: 1/5 + 1/10 + 1/10 + 1/10 + 1/5 + 1/10 + 1/10 + 1/10 = 1
C: 1/6 + 1/6 + 1/6 + 1/6 + 1/6 + 1/6 = 1

Answer:
232
Step-by-step explanation:
9 x 25 = 225 225 + 7 = 232
another way to find it
9 x 20 = 180 9 x 5 = 45 180 + 45 = 225 + 7 = 232
