Answer: Choice A
Step-by-step explanation: You are given the inequality g is less than or equal to. Greater/less than and equal to, you use solid circle. Greater/less than, you use open circle. From there, you just look at the inequality in which direction is it going at and from there, you should be able to select your choice which happens to be the first one.
I hope this explanation helps.
Best to you!
Answer:
Write the problem as a mathematical expression.
b(12)=4.8b
Move 12 to the left of b.
12b=4.8b
Move all terms containing b to the left side of the equation.
7.2b=0
Divide each term by 7.2 and simplify.
b=0
