In order for it to be divisible by 5 AND be an even number, it must also be divisible by 2. So you are looking for two-digit numbers greater than 34 and divisible by 10:
C = {40, 50, 60, 70, 80, 90}
Answer:
Very similar to solving an equation.
Step-by-step explanation:
You have to use the properties of equality to "undo" each number and isolate the letter to one side.
How ever, if you are multiplying or dividing by a negative number, then the inequality must be reversed.
