Chris and Ben walked home from school. The distance Chris walked,in miles, is represented by point C on the number line. Ben walked 1/4 mile less than Chris walked. Enter the distance,in miles, Ben walked.

The distance Ben walked, in miles for this considered situation is C - 1/4 miles.

How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

We're provided that:

- C = the number of miles Chris walked
- Ben walked 1/4 miles less than what Chris walked.

"1/4 less than what Chris walked"

is "1/4 less than C miles"

C - 1/4 is the amount of miles which is 1/4 less than C miles.

Thus, the distance Ben walked, in miles for this considered situation is miles.

How do you write 3.25 in simplest form

3.25 would be 3 1/4 because,

Step 1: You would rewrite the decimal number as a fraction with 1 in the denominator. So, 3.25 = 3.24/1

Step 2: Multiply it by 1 to eliminate 2 decimals places, so multiply the top and bottom by 10^2 = 100

3.25/1 x 100/100 = 325/100

Step 3: Now you find the greatest common factor, also known as GCF, of 325 and 100 if it exits then you reduce the fraction by dividing both numerator and denominator by it. GCF = 25

3.25/100 divided by 25/25 = 13/4

Now you would simplify it to make a proper fraction getting your answer

3 1/4

Does that make sense?

Now you would simplify it to make a proper fraction getting your answer

3 1/4

Does that make sense?

3.25 as a fraction is 325/100 I believe.

Convert the standard form equation into slope-intercept form 4x -3y =15

Answer:

y = (4/3)x - 5.

Step-by-step explanation:

4x - 3y = 15

-3y = -4x + 15

Divide though by -3:

y = (4/3)x - 5 .

Explain why the greater than or equal to and less than or equal to symbols have a closed circle, while the greater than and less than symbols have an open circle.

the circle is closed because it can also include that number or be equal to it, when the circle is open that number isn't an option and is just a starting point.
