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

An angle cannot be the complement of one angle and the supplement of another angle at the same time. is this true or false?
soldi70 [24.7K]

An angle cannot be the complement of one angle and the supplement of another angle at the same time. Then the given statement is false.

<h3>What is an angle?</h3>

The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.

Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.

Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.

An angle cannot be the complement of one angle and the supplement of another angle at the same time.

Then the given statement is false.

More about the angled link is given below.
