Step-by-step explanation:
Eighty, decreased by three times an number, is the same as five times the number, increased by eight. Then the number is 9
<h3><u>
Solution:</u></h3>
Given that eighty, decreased by three times an number, is the same as five times the number, increased by eight
<em><u>To find: the number</u></em>
Let the required number be "a"
Let us break the given sentence
<em>Eighty decreased by three times an number = five times the number increased by eight</em>
Here "times" represents multiplication and "decreased" represents subtraction and "increased represents "addition"
80 - three times "a" = 5 times "a" + 8
80 - 3a = 5a + 8
80 - 8 = 5a + 3a
8a = 72
<h3>a = 9</h3>
Thus the required number is 9
The answer is B. Because X and Z are considered congruent.
