Question:
Five times the sum of a number and 27 is greater than or equal to six times the sum of that number and 26.
What is the solution set of this problem?
Answer:
Step-by-step explanation:
Given
<em>Represent the number with x</em>
So:
Required
Determine the solution set

Multiply both sides by -1
Hence, the solution set is
Lets calculate how much she walks each weeks and then we multiply that by the number of weeks.
weekWalk = 5(2) + 3 = 10 + 3 = 13
therefore, she walks 13 miles per week, if she walked for 29 weeks then we have:
total walked =(29)(13) = 377
so she walked 377 miles total, so her original estimate is not reasonable

Answer:
D. 
Step-by-step explanation:
Consider the set
This set consists of four ordered pairs.
The first numbers in these pairs are 
These numbers are integer numbers (not natural, because -3 is negative).
The second numbers in these pairs are 
These numbers are integer numbers too (not natural, because -2 is negative).
Options contain only natural and real sets, so, the first and the second numbers are real numbers and
