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.

What is gif of 18 and 24
babunello [35]

Answer:

6

Step-by-step explanation:

I assume you mean GCF, greatest common factor.

First, write the prime factorizations for each:

18 = 2¹ × 3²

24 = 2³ × 3¹

Next, find what they have in common.  Both have a factor of 2¹ and 3¹.

GCF = 2¹ × 3¹

GCF = 6

The greatest common factor is 6.
