Answer:

-1.2

Step-by-step explanation:

3n + 5 = 1/2(11n + 16)

3n + 5 = 5.5n + 8

5 = 2.5n + 8

-3 = 2.5n

-3/2.5 = n

-1.2 = n

Hope this helps!

Answer:

n=-1.2

Step-by-step explanation:

First, solve both sides of the equation:

3n+5=\frac{1}{2} (11n+16)

3n+5=(\frac{1}{2} )(11n)+(\frac{1}{2} )(16) (Distribute)

3n+5=\frac{11}{2} n+8

Then, subtract 11/2 n from both sides:

3n+5-\frac{11}{2}n=\frac{11}{2} n+8-\frac{11}{2} n

\frac{-5}{2}n+5=8

Now, subtract 5 from both the sides:

\frac{-5}{2} +5-5=8-5

\frac{-5}{2} n=3

For the last step, multiply both the sides by 2 / -5

(\frac{2}{-5} )*(\frac{-5}{2} )=(\frac{2}{-5} )*(3)

n=\frac{-6}{5}

Convert it to decimal:

n=-1.2

Write a conditional statement. Write the converse, inverse, and contrapositive for your statement and determine the truth value
MrRa [10]

Conditional statement is a statement with a hypotesis and a conclusion:

If \text{ \underline{ hypothesis } } p, then \text{ \underline { conclusion }  } q

or mathematically p\rightarrow q.

Converse statement of p\rightarrow q is statement q\rightarrow p.

If you negate (that means stick a "not" in front of) both the hypothesis and conclusion, you get the inverse:

\neg p\rightarrow \neg q.

Finally, if you negate everything and flip p and q (taking the inverse of the converse) then you get the contrapositive:

\neg q\rightarrow \neg p.

Example:

1. Conditional statement: If I am sleeping, then I have closed eyes. (true)

2. Converse statement: If I have closed eyes, then I'm sleeping. (not necessarily true)

3. Inverse statement: If I'm not sleeping, then I haven't closed eyes. (not necessarily true)

4. Contrapositive statement: If I haven't closed eyes, then I'm not sleeping. (true)
