and 
Step-by-step explanation:
Given the expressions:
1)
2)
To find:
The expressions equivalent to the given expressions.
or the expressions which are not equivalent to any of the given expressions.
Solution:
First of all, let us solve the brackets from the given expressions.
can be written as (because when we multiply a negative sign with negative, it becomes positive.)
Similarly can be written as (because when we multiply a positive sign with negative, it becomes negative.)
Therefore, the answer is:
is equivalent to and
is equivalent to and .
The expressions which are equivalent to neither:
and
Answer:
D is the answer
Step-by-step explanation:
Answer:
x > 12, so the answer is the last one or D
Step-by-step explanation:
2/3x − 5 > 3
Step 1: Add 5 to both sides.
2/3x − 5 + 5 > 3 + 5
2/3x > 8
Step 2: Multiply both sides by 3/2.
2/3x * (3/2) > 8 * (3/2)
x > 12
> = open circle
< = open circle
≤ = closed circle
≥ = closed circle
Answer:
3.6
Step-by-step explanation:
The 6 is in the tenth place. Because the 1 is less than 5, it turns into 0.
