Im trying to solve this but don’t understand how m-3(-5x+2)+x=42

Mathematics

-3(-5x+2)+x=42
Distribute the -3 to the -5 and 2 so you would be left with
15x-6+x=42
Then you combine like terms and the x’s
16x-6=42
Add the 6 to the 42
16x=48
Then divide by 16 on both sides
X=3

I hope that helped.

Factor 4m^2 +16m+15
PSYCHO15rus [73]

Split the second term in 4m^2 + 16m + 15 into two terms

4m^2 + 10m + 6m + 15

Factor out the common terms in the first two terms, then in the last two terms

2m(2m + 5) + 3(2m + 5)

Factor out the common term 2m + 5

(2m + 5)(2m + 3)

You read online that the probability of being dealt four‑of‑a‑kind in a five‑card poker hand is 1 / 4165. Explain carefully what
Lapatulllka [165]

Answer:

There is about 4,164/4,165 chances of not getting getting a four of a kind. So, it is extremely unlikely or even borderline impossible in that situation to get a four of a kind.

<u>But in the long run, it can be increased only if you keep drawing.  So, the awnser would have to be. D  </u>

Step-by-step explanation:

A. It does mean that if you are dealt 4165 five‑card poker hands, one will be four‑of‑a‑kind.

B.  It does not mean that all will be four‑of‑a‑kind. The probability is actually saying that only on the 4165 the poker hand will you get a four‑of‑a‑kind, not just on any of the 4165 poker hands.

C. The probability is actually saying that in the long run, with a large number of five‑card poker hands, the fraction in which you will be dealt a four‑of‑a‑kind is 1 / 4165.

D. The chance you will be dealt four‑of‑a‑kind is 1 / 4165 only on the first hand. This chance will then increase with each new hand you are dealt until you eventually win

How do i solve this problem?
uranmaximum [27]

Answer:

Step-by-step explanation:

Simplifying

N(t) = 300.9   Multiply N * t  tN = 300.9  Solving  tN = 300.9   Solving for variable 't'.   Move all terms containing t to the left, all other terms to the right.   Divide each side by 'N'.  t = 300.9N-1   Simplifying  t = 300.9N-1
