Do you need an example? If so, 2x + 4 greater than or equal to 24. If you need to know how to do them. Check the image. These are two step inequalities because you have to subtract from both sides THEN divide to get x by itself. Hope I helped.
Answer:
d. 4
Step-by-step explanation:
total amount Frank is willing to pay is 1000 + 850 + 700 + 500 = $3050
given the price of a class cost $750
therefore,
total number of classes he will be able to take = total amount frank is willing to pay/ price per class
so, 3050/750
= 4.067
approximately = 4
If B is the midpoint, AB and BC must be of equal length.
12x-12=4x+28
Subtract 4x from both sides
8x-12= 28
Add 12 to both sides
8x= 40
Divide both sides by 8
x=5 <======
Now plug in this value of x
12(5)-12= 60-12 = 48 <========
4(5)+28= 20+28= 48 <=======
Add the values to get AC
48+48= 96 <======
I don't think that anybody in Elementary School would Understand this you might want to post this question in the High School section.
Hope it gets answered :)
