13, because 442/34 is 13 meaning each person sold an equal amount
To add the two expressions, we can write it as:
4.6x-3 + (-5.3x+9)
We can distribute the plus sign (which means just drop the parenthesis in this case):
4.6x-3-5.3x+9
Now, we can simplify by combining like terms:
-0.7x+6
Answer:
Negative numbers don't have real square roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can't be written as the quotient of two integers.

The trigonometric expression sin 30° will be equal to cos 60°. Then the correct option is E.
<h3>How to convert the sine of an angle to some angle of cosine?</h3>
We can use the fact that:
sin(θ) = cos(90 - θ)
To convert the sine to cosine (but the angles won't stay the same unless it's 45 degrees).
The trigonometric expression sin 30° will be equal to
The sin 30° can be written as
sin 30° = cos(90° - 30)
sin 30° = cos 60°
Then the correct option is E.
