Problem 1
Answer: Choice B. X is greater than or equal to 4
The closed circle at 4 indicates that this value is included in the solution set. So we will have an "or equal to" as part of the answer. The shading to the right suggests "greater than". Combine "greater than" and "or equal to" and we have a "greater than or equal to" sign.
===================================================
Problem 2
Everywhere is shaded but -4 on the number line. So x can be any number but -4. The answer isn't listed (probably got cut off), but it should be 
(x is not equal to -4). The slash through the equal sign means "not equal to"

Answer:
<u>7 groups of 8 = 6 groups of 8 plus 1 group of 8</u>
Step-by-step explanation:
1. Let's review the information given to answer the question correctly:
7 groups of 8 = 6 groups of 8 plus ?
2. Let's answer the question, this way:
How much are 7 groups of 8? 56 = 7 * 8
How much are 6 groups of 8? 48 = 6 * 8
What is the difference between 7 groups of 8 and 6 groups of 8?
(7 - 6 ) * 8 = 1 * 8
Therefore,
<u>7 groups of 8 = 6 groups of 8 plus 1 group of 8</u>
Answer:
the difference is 1/21
Step-by-step explanation:
2/3 equals 14/21 and 5/7 equals 15/21
Step-by-step explanation:
1/3x-10/3=-4
1/3x=-4+10/3
1/3x=-2/3
