Answer:

last choice

Step-by-step explanation:

If we are looking at positive integers and we take out the odd ones, the only one's that are left are the even ones.

So last choice. (Also I assume AC meant the complement of A)

2= 7+ b/4 in two-step equation-integers

Rama09 [41]

Answer:

b=-20

Step-by-step explanation:

We will have to solve this question based on how the question is given

So let's solve the given question

2=7+b/4

To start by finding the LCM for the right side and the LCM is 4

2=28+b/4

Let's cross multiply

2×4=28+b

8=28+b

Let's make b the subject of formula by substrating 28 from both sides

-20=b

Therefore the final answer is b=-20
