Answer:
Answer choice A is the correct answer
Step-by-step explanation:
** Before you start: If anything that is < or > you shouldn't fill in the plot.
If it has ≤ or ≥then you need to fill in the plot.**
Terminology:
(>) : Greater than (Don't fill in)
(<): Less than (Don't fill in)
(≤) : Less than or equal to (Fill in)
(≥) : Greater than or equal to (Fill in)
In this case, the answer choices C and D are wrong automatically.
Your Inequality:
11g + 5 ≤ 49
Subtract 5 both sides
11g ≤ 49-5
11g ≤ 44
Divide 44 by 11
g ≤ 4
Find an answer choice that has a number greater than 4 but has a filled-in circle/plot.
