Hello!
To solve any algebraic equation, you need to use SADMEP. SADMEP is an acronym for subtraction, addition, division, multiplication, exponents and parentheses. Our goal is to isolate the variable, x.
24 - 4x = 15 - 3x + 10 - x (simplify)
24 - 4x = 25 - 4x (subtract 24 from both sides)
-4x = 1 - 4x (add 4x to both sides)
1 = 0
This equation has no solutions because 1 and 0 are <u>never equal</u> to each other, which means that this is identified to be neither because it <u>has no real solutions</u>.
I believe that the mode is 12 hope that answered your questions!
Answer:
Option C is the answer.
Step-by-step explanation:
Given diameter is = 2 miles
So, radius will be = 1 mile
Let t represents the number of hours it took Johanna to walk completely around the lake.
Now, the circumference is given as: ![2\pi r](https://tex.z-dn.net/?f=2%5Cpi%20r)
So, circumference =
= 6.28 miles
Johanna's speed = 3 miles/ hour
We know the formula ![Time=Distance / Speed](https://tex.z-dn.net/?f=Time%3DDistance%20%2F%20Speed)
t = ![6.28/3](https://tex.z-dn.net/?f=6.28%2F3)
t = 2.09 hours
This is greater than 2, but less than 2.5, therefore, 2.0 < t < 2.5 is the answer.
