You can do prime factorization then find common factors to factor out.
6m² - 15m
2·3·m·m - 3·5·m
Both terms have 3·m so we can factor it out:
3·m (2·m - 5)
So that would be 3m (2m - 5)
458
the answer is the last one
I think it’s 12
1/3 = 4/12
1/4 = 3/12
Hope it’s correct
Let x be amount of music lessons
Member = 100 + 20x
Non member = 30x
Must be same, so 100 + 20x = 30x
Solve for x:
Group like terms.
100 = 30x - 20x
100 = 10x
100/10 = x
x=10
10 music lessons for member and non member to have same costs of $300.
Im not very good at maths. But this seems easy :D. I'm still a beginner, but please give me points.
