Answer:
OPTION A
OPTION B
OPTION C
Step-by-step explanation:
Irrational numbers are the subset of real numbers. Their decimal representation neither form a pattern nor terminate.
OPTION A: 
This is equal to 
.
is non-terminating. So, it is an irrational number. Hence, the reciprocal of an irrational number would also be irrational. So, OPTION A is irrational.
OPTION B: 
This is equal to 
. Using the same logic as Option A, we regard OPTION B to be irrational as well.
OPTION C: 
This is equal to 
.
Both 
and 
are irrational. So, the product and the reciprocal of the product is irrational as well. So, OPTION C is an irrational number.
OPTION D: 
16 is a perfect square and is a rational number. 
= 
. This is equal to 0.25, a terminating decimal. So, OPTION D is a rational number.
OPTION E: 
4 is a perfect square as well. 
, a terminating decimal. So, OPTION E is a rational number.
If a must be less than -9, we are just to pick a number less that-9 (-10) and plug it in for a
-10 + b> -4
What must make this sentence true?
-10 +b> -4
+10 +10
B > 5
Answer:
52%
Step-by-step explanation:
62/120 * 100%
Divide by 2 on top and bottom
31/60 * 100 %
.5166666666 * 100 %
51.66666666 %
To the nearest whole number
Rounding the 1, we look at the 6 6>=5 so we round the 1 to 2
52%
You want to try and get rid of one of the variables ( x or y) so you would multiply the second equation by 2 which would make the x variable -2x which then when added to the first equation would eliminate the x variable.
Answer: c. Multiply the second equation by 2.
