Answer:
C: Irrational
Explanation:
the reason i chose C because when you add a rational and irrational number together you still get a repeating number which is irrational.
For Example: Take a rational number 5 and Pi
if you ad those together 5+3.1415... you still get a repeating decimal, and repeating decimals are also irrational numbers.
Hope this helps :D
Answer:
A) 20.82 > 20.55
Step-by-step explanation:
Hopefully, your issue is with the symbols (< vs >) rather than actually determining which number is larger or smaller.
The wide-open end of the symbol (the left side, in the case of >) indicates the larger (more positive) number.
So, the meanings of the symbols are ...
> — "is greater than"
< — "is less than"
The only true statement of those listed is ...
20.82 is greater than 20.55, or 20.82 > 20.55 . . . . selection A
_____
When writing number comparisons, I like to use the < symbol, because it puts the numbers in number-line order. That is, the smaller (or more negative) number is on the left, just as it is on a number line.
You trade the places of the numbers when changing the symbol. For example, answer choice A could be rewritten as ...
20.55 < 20.82
You know that 20.55 is to the left of 20.82 on the number line, so you know this statement is true.
Answer:
=14x² −3x −1
Step-by-step explanation:
simplifying step-by-step.
9x2+5x2+5x−3−(8x−2)
Distribute the Negative Sign:
=9x2+5x2+5x−3+−1(8x−2)
=9x2+5x2+5x+−3+−1(8x)+(−1)(−2)
=9x2+5x2+5x+−3+−8x+2
Combine Like Terms:
=9x2+5x2+5x+−3+−8x+2
=(9x2+5x2)+(5x+−8x)+(−3+2)
=14x2+−3x+−1
Answer:
=14x2−3x−1
Answer:
x = -25/3
Step-by-step explanation:
The equation simplifies to -3x - 25 = 0, so
-3x = 25 =>
x = -25/3
