First, we want to subtract the numbers within the parenthesis. However, to do this we must put each number over a common denominator. We can do his by multiplying
6
by the appropriate for of
1
:
2
3
(
6
−
5
6
)
⇒
2
3
(
[
6
6
×
6
]
−
5
6
)
⇒
2
3
(
36
6
−
5
6
)
⇒
2
3
(
31
6
)
Next, we can multiply the two fractions to complete the evaluation of the expression:
2
3
(
31
6
)
⇒
2
3
×
31
6
⇒
2
×
31
3
×
6
⇒
62
18
Now, we can factor the numerator and denominator so we can cancel common terms. This will give the simplest form of the fraction:
2
×
31
2
×
9
⇒
2
×
31
2
×
9
⇒
31
9

I am really trying my best to get upgraded. My other accont is acting up and I lost what I was trying to do to get upgraded again, so please give me Brainliest
You reverse the inequality when you divide both sides by a negative number.
example:
-5x>45 (you divide both sides here by -5 to get the value of x)
answer:
x<9 (notice inequality has been has been reversed)
Answer:
Step-by-step explanation:
We know all angles in a circle or around a point is 360°
So using that we can make the equation:
the angles e and f are on a straight line so they add up to 180°
So the other side of the line will be 180 as well. Hence we can make the equation:
X=9
You would do 54 divided by 5x and it would equal to 9 that means x is 9
Answer:
The answer is the option D
Step-by-step explanation:
we know that
The inequality
has two solutions
<u>First solution</u>
The solution is the interval-------> (2,∞)
All real numbers greater than 
<u>Second solution</u>
------>
-
The solution is the interval-------> (-∞,-2)
All real numbers less than
