Answer:

23-40

Step-by-step explanation:

First, you do 63 - 23, which would be 40. Since 23 to 40 is the simplest form of this ratio, no extra steps are needed. Order is important in ratios, so paperback to hardcover would be a ratio of 23 to 40, or 23-40.

Applying Properties of Exponents In Exercise,use the properties of exponents to simplify the expression.
Eduardwww [97]

Answer:

1. ~e^5\\2. ~e^{\frac{3}{2}}\\3. ~e^6\\4.~ e^7

Step-by-step explanation:

We have to simplify the given exponential expressions

Exponential properties:

e^0 =1\\e^a.e^b = e^{a+b}\\\\\displaystyle\frac{e^a}{e^b} = e^{a-b}\\\\(e^a)^b = e^{ab\\\\e^{-a} = \frac{1}{e^a}

Simplification takes place in the following manner:

1)

(e^2)^\frac{5}{2}\\\text{Applying the exponential property}\\\\=e^{2\times \frac{5}{2}}\\= e^5

2)

(e^2)(e^{\frac{1}{2}})\\\text{Using the exponential propert}\\\\= e^{2 + \frac{1}{2}} = e^{\frac{3}{2}}

3)

(e^{-2})^{-3}\\= e^{-2\times -3}\\=e^6

4)

\displaystyle\frac{e^5}{e^{-2}}\\\\\text{Using exponential properties}\\\\= e^{5-(-2)} = e^7

GUYS please
Advocard [28]

Answer:

2.64

Step-by-step explanation:

0.9(x + 1.4) - 2.3 + 0.1x = 1.6

0.9x + 1.26 -2.3 + 0.1x - 1.6 = 0

(0.9x + 0.1x) + (1.26 - 2.3 - 1.6) = 0  

x - 2.64 = 0

x = 2.64

How do you solve two step equations?
Lelechka [254]

Lets say you are trying to find the X in this equation:

2x-8=18     1. find a way to leave the 2x by itself.

2x=26         2. since the 8 is a negative (-8), becase it has a  subtraction               sighn , you add it to the 18 on the opposite side so yu have the 2x by itself.

                   3. Now you have to divide since there is nothing else you can do.

You divide 26 by two and then 2 by 2. now you have x=13. 

This technique goes the same for if you have more that just two numbers that dont have a variable, but you said two step, so this is a prime example.  I hope this helped. :)
