Answer:

Step-by-step explanation:

First, you have to follow the order of operations. (PEMDAS) So you would simplify the numbers inside of the parenthesis, (4*2), and (5-3). The equation then becomes 20 - (8) / (2). Next, you do multiplication and division next, since there is no exponent. 20 - 4. You then simplify the rest by subtracting. 20 - 4 = 16. There is your answer.

Answer:

Ian sold 7 rolls of wrapping paper.

Step-by-step explanation:

Let E be the number of rolls of wrapping paper sold by Evan and I be the number of rolls of wrapping papers sold by Ian.

We have been given that Evan sold twice as many rolls of wrapping paper as Ian. We can represent this information in an equation as:

$E=2I...(1)$

We are also told that Evan sold 14 rolls.

We can represent this information in an equation as:

$E=14...(2)$

To find the number of rolls of wrapping paper sold by Ian we will equate our both equation as:

$2I=14$

Let us divide both sides of our equation by 2.

$\frac{2I}{2}=\frac{14}{2}$

$I=7$

Therefore, Ian sold 7 rolls of wrapping paper.

Write the following quotient in the form a+bi.<br> -7i/2-7i

Helga [31]

Answer:

$\large\boxed{\dfrac{49}{53}-\dfrac{14}{53}i}$

Step-by-step explanation:

$\text{Use}\\\\i=\sqrt{-1}\to i^2=-1\\\\(a-b)(a+b)=a^2-b^2\to(a-bi)(a+bi)=a^2+b^2\\\\\text{distributive property}\ a(b+c)=ab+ac\\---------------------\\\\\dfrac{-7i}{2-7i}=\dfrac{-7i}{2-7i}\cdot\dfrac{2+7i}{2+7i}=\dfrac{-7i(2+7i)}{2^2+7^2}=\dfrac{(-7i)(2)+(-7i)(7i)}{4+49}\\\\=\dfrac{-14i-49i^2}{53}=\dfrac{-14i-49(-1)}{53}=\dfrac{-14i+49}{53}\\\\=\dfrac{49}{53}-\dfrac{14}{53}i$
