Brenda has to take out the trash more than 4 times to have more than $50.
Step-by-step explanation:

Amount Brenda already have = $30
Amount she gets each time for throwing trash = $5
Amount she wants to have = More than $50
Let,
x be the number of times she throws trash.
Amount for throwing trash * Number of times trash thrown + Amount already have > Amount she wants to have

Dividing both sides by 5

Brenda has to take out the trash more than 4 times to have more than $50.

Answer:
Step-by-step explanation:
1. Make 1 2/7 an improper fraction = 9/7
2. Multiply 7 on both numerator and denominator for 2/3 to make 14/21, and multiply 3 for both numerator and denominator for 9/7 to make 27/21.
3. Add them together. 14/21+27/21=41/21.
