(3x+8)+x>3x-12 can someone tell me how to solve it because already know the answer which is x>-20

Answers

Answer 1

Answer: (3x + 8) + x > 3x - 12
3x + x + 8 > 3x - 12
      4x + 8 > 3x - 12
      - 3x     - 3x
      x + 8 > -12
      - 8   - 8
      x > -20

Solution Set: (-∞, -20)

Your answer: -2x(5x^2+4x+5)

(Simplified = 10x^3 + 8x^2 + 10x)

Round 3,989.23655 to the nearest thousandth.

Answers

3,989.23700 would be the answer because you take five and round six to seven. Everything that follows that becomes a zero.

$(1)/(sec^2\theta)=cos^2\theta\n\nL=(1)/(\left((1)/(cos\theta)\right)^2)=(1)/((1)/(cos^2\theta))=1:(1)/(cos^2\theta)=1\cdot(cos^2\theta)/(1)=cos^2\theta=R$

many colleges determine the number of full time students f,by using the formula f=n/15 where n is the total number of credits for each semester if a student registers for 46140 credits how many full time students does the campus have. then what is the formula for n n=

Answers

"A student" doesn't register for 46,140 credits, unless he wants to be very very busy.

If ALL of the students on campus register for 46,140 credits, then many colleges
would estimate the number of full-time students by using the formula

f = n / 15 = 46,140 / 15 = 3,076 students.

That's not the formula for 'n'. 'n' is the total number of credits for the semester,
and the question tells you what 'n' is. Knowing 'n', the formula helps you find 'f'.

You are walking down a road seeking treasure the real branches of into 3 paths a guard stands in each path you only know that only one of the girls is telling the truth and the other two are lying this is what they say guard one the treasure lies down this path guard to no treasure lies down this path seek elsewhere Garth 3 the first guard is lying

Answers

Answer:

Guard Two

Step-by-step explanation:

Guard two has the path to the treasure because he's telling people that there's no treasure. That makes him suspicious because he might want the treasure for himself

Final answer:

This is a logic puzzle wherein the guards' statements are evaluated based on the given criteria: only one guard is truthful. Upon analysis, we find that only the path guarded by Guard 2 aligns with this criteria, indicating that this is the path you should take to find the treasure.

Explanation:

This is a classic logic problem, often called the 'Liar and Truth-Teller' puzzle. Here's how we can tackle it:

Guard 1 says: 'The treasure lies down this path.'

Guard 2 says: 'No treasure lies down this path, seek elsewhere.'

Guard 3 says: 'The first guard is lying.'

Since we know that only one guard is telling the truth, let's consider if Guard 1 tells the truth. If so, Guard 2 and Guard 3 would be lying, which contradicts the statement of Guard 3 (who confirms Guard 1's statement as a lie).

If Guard 2 is telling the truth (which means there's no treasure on his path), then both Guard 1 and Guard 3 would be lying, which fits our criteria.

If Guard 3 told the truth, this would mean that Guard 1 is lying, but then Guard 2 would also be telling the truth--this contradicts our initial information (only one guard is truthful).

So, based on these evaluations, you should take the path guarded by Guard 2 because he's the only one telling the truth according to the given criteria.
