To figure out which is not equivalent to the others,, we must solve each option provided. x < -2 is already solved,, so there is no need to do any work that option.
The first step for solving x - 2 < 4 is to move the constant to the right side and then change its sign.
x < 4 + 2
Now add the numbers together to get your final answer.
x < 6
This means that we have one option that equals x < -2 and one option that equals x < 6.
Let's now solve 2x < -4 to see what that one equals. In order to solve this,, we need to divide both sides of the inequality by 2.
x < -2
Now we can see that it looks like all of the expressions are equivalent except for x - 2 < 4. Before we can confirm this though,, let's solve for x - 2 < -4. The first step for solving this is to move the constant to the right side and change its sign.
x < -4 + 2
Now calculate the sum of these two numbers to get your final answer.
x < -2
This tells us that all of the options are equivalent except for x - 2 < 4,, or option B.
Let me know if you have any further questions.

Answer:
one-quarter times the number of pears, plus four and one-half is forty-four and one-half
Step-by-step explanation:
The total weight (44.5 lb) will be the sum of the empty weight (4.5 lb) and the number of pears multiplied by the pear's weight. That can be expressed as ...
one-quarter times the number of pears, plus four and one-half is forty-four and one-half
Answer:
15 14/15
Step-by-step explanation:
8 + 7 = 15
1/3 + 3/5
5/15 + 9/15
14/15
15 + 14/15 = 15 14/15

Answer:
70 sq. in
Step-by-step explanation:
Area of the figure
= ( 10 x 5 ) + ( 5 x 4 )
= 50 + 20
= 70
= 70 sq. in
