The following map shows the location of a mall, library, and school in a city: Mike traveled from the school to the mall and then from the mall to the library. Henry traveled from the school to the library. How many more miles did Mike travel than Henry? A.) 10
B.) 12
C.) 34
D.) 46

Mike: From the school to the mall, we could count out 16 units. From the mall to the library, we could count out 29 units. When we add 16 and 29, we get the distance Mike traveled: 45 units.

Henry: He traveled from the school to the library. To find out how long this distance is, we look at our previous numbers. From the school to the mall: 16. From the mall to the library: 29

To solve, we need to know the Pythagorean Theorem. We use the formula a^2 + b^2 = c^2. Here, 16 is a and 29 is b. We need to square both numbers and add them together to get c^2.

Then, we have to square 1097 to find c.

√1097 ≈ 33

Total: We subtract Henry's distance from Mike's to get our final answer.

45 - 33 = 12

Mike traveled 12 more units than Henry.

Substitute y = 2 in 2x + 8y = 20 to get

2x + 8y = 20 
>> 2x + 8(2) = 20
>> 2x + 16 = 20
>> 2x + 16 -16 = 20 - 16
>> 2x = 4
>> 2x / 2 = 4 / 2 
>> x = 2

So x = 2, y = 2 is the solution. In order pair form (x,y) = (2,2)
