Question

How did Jo help to settle Laurie’s room and what did she bring for him from her house? What are the things you can do for your neighbours to maintain a good relationship with them?

Answer 1

Explanation:

There are x number of boys and there are x+30 girls

Added together they will add up to 150

x+x+30=150 or 2x+30=150

2x=150–30 or 2x=120 and x = 60

There are 60 boys and 60 + 30 girls for 90 girls.

Quick check 90 is 30 more than 60 and 90 + 60 = 150
