Answer:

4 -9/20

Step-by-step explanation:

separate whole numbers and fractions: 9-5, 3/10 - 3/4

then you subtract the whole numbers: 4

after that (what i mostly use that is easy for me is cross multiplication/ Butterfly method)

12    -     30

<u>3</u>      -      <u>3</u>    =   <u>-18</u>  = <u>-9</u>

Attachment below <br> algebra helppppp

Answer: second option.

Step-by-step explanation:

In order to solve this exercise, it is necessary to remember the following properties of logarithms:

1)\ ln(p)^m=m*ln(p)\\\\2)\ ln(e)=1

In this case you have the following inequality:

e^x>14

So you need to solve for the variable "x".

The steps to do it are below:

1. You need to apply ln to both sides of the inequality:

ln(e)^x>ln(14)

2. Now you must apply the properties shown before:

(x)ln(e)>ln(14)\\\\(x)(1)>2.63906\\\\x>2.63906

3. Then, rounding to the nearest ten-thousandth, you get:

x>2.6391

615.44 to the nearest hundredth
Leya [2.2K]
When rounding, look to the next place to the right of what you are rounding to... for example if you are rounding to the nearest hundredth, look to the thousandths place to see if the hundredths place rounds up or down. Since your number, 615.44 stops on the hundredths place, the thousandths place is automatically zero, so your number stays the same.
