Question

Set B is the set of positive two-digit odd numbers greater than 49 that are divisible by 5.

Answer 1

Answer:

B = {55, 65, 75, 85, 95}

Step-by-step explanation:

A set is a list or group of numbers. We use these { } squiggly brackets to contain the list of numbers. Two-digit numbers are 10 to 99. But they said we're starting from 49. So our list will have only numbers between 49 and 99. BUT, they also said divisible by 5. Numbers divisible by five end with a 0 or 5...so, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95...BUT: they also said ODD numbers. So we only keep the numbers ending in 5.

Finally, we end up with B = {55, 65, 75, 85, 95}
