8.3*4 = 33.2 kg.
Hopefully that is correct
Since Yi Ting weighs 8.3 and her brother is 4 times heavier you would multiply those two numbers to get the answer.

A because x is the original price, so you multiply by the tax (9%) which would convert to 1.09 which you would multiply to the x

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

By using the given value,

$\angle{w'x'y'}=$ 92°

Hence, option (C) is correct.

Twice x, plus 4, is the same as -6.

BARSIC [14]

Start by writing what is said:
2x + 4 = -6
From there just solve for x:

Subtract 4 from both sides
2x + 4 - 4 = -6 - 4
2x = -10

Divide by 2 to get x by itself
2x/2 = -10/2
x = -5
