Answer:
The formula to find the area of a circle is pi times the radius squared (A = π r²).
Step-by-step explanation:
So its going to equal a fraction.
To convert let x equal the repeating decimal (0.1515... it would usually have a line on top of it but I cant type it)
Then examine the number see what place it is in then add another place (in this case it is in the 10000ths place) so multiply it but 10000x
so it would look like: 10000x = 0.1515
then you will move the decimal in to a whole numbers place (0.1515 to 1515.1515
then subtract the decimal 1515.1515- .1515= 1515.
dont forget to subtract from both sides so subtract the 10000x too. (999.515)
then write as fraction form 1515/9999

-9; x
6 or in interval notation [-9,6]
To find out what are the steps in solving the below inequality:
Given equation is 2x - 3 > 15
The absolute value function takes any term and transforms it to its non-negative form. Therefore, we must solve the term within the absolute value function for both its negative and positive equivalent.
−15≤2x-3≤15
First, subtract 3 from each segment of the system of equations to isolate the x term while keeping the system balanced:
−15−3≤2x-3−3≤15−3
−18≤2x-6≤12
−18≤2x-6≤12
Now, divide each segment of the system by 2 to solve for x while keeping the system balanced:

The lines will be a solid line because the inequality operators contain "or equal to" clauses.
We will shade between the lines to show the interval:

Answer:
10x-5
Step-by-step explanation:
You subtract 15x-5=10x. Then you do -7+2. The 7 is negative . So it would be -7 plus two. So it would equal -5. So it's 10x-5
