Answer:
25 people
Step-by-step explanation:
So, you're trying to find how many she needs to invite since only 92% show up. With this problem, you need to figure out 92% of what number is 23. An equation for this is:
92/100 = 23/x
1. Cross multiply to get 92x=2300
2. Divide both sides to get x by itself. You should get x= 25
3. So, she should invite 25 people
That would be the inverse property of addition. When you add the
opposite of a number to that number, your sum will be zero. -a is the
opposite of a and -bi is the opposite of bi. When you add x + y (aka the
opposites) your total is absolutely nothing!
The answer would be the second one
