Answer:

-1

Step-by-step explanation:

Put -2 3/4 into an improper fraction -6/4

Then put it into a decimal -1.5

Then put 1/2 into a decimal 1.5

Then divide -1.5 by 1.5

You would get -1

Answer: -5 1/2

Step-by-step explanation:

When dividing fractions, we follow a rule called "Keep, change. flip." You keep the first fraction the same, change the division symbol to a multiplication symbol, and flip the last fraction.

-2 3/4 turned into an improper fraction: 4 * 2 + 3 = 11/4

11 * 2 = 22

4 * 1 = 4

= -22/4

4 goes into 22 5 times, but we'd still have 1 left over.

5 2/4

This can be reduced once more to 5 1/2

Then we add the negative sign back in.

-5 1/2.

A quadrilateral WXYZ contains wxy where measure of wxy=92 degrees. Once rotated 270° about the origin and translated 2 units up,

Marianna [84]

Answer:

C. 92 degrees

Step-by-step explanation:

Given that the $\angle{wxy}=$ 92° which is one of the angles of the quadrilateral WXYZ

The quadrilateral is first rotated by 270° about the origin and then translated 2 units up, the new position of the quadrilateral is W'X'Y'Z'.

The shape of the quadrilateral is remained unchanged due to rotation and translation, so all the angles of the final quadrilateral W'X'Y'Z' is the same as the angles of the given quadrilateral WXYZ.

So, $\angle{w'x'y'}= \angle{wxy}$
