The slope is -10, I used a graph for this.
x = 150 did this help you?
Because + and - make - which makes you left with 3-5 which equals to -2 because it gets negative.
12
2 multiplied by 6 is 12 and so 1 multiplied by something is 12
Hope this helps.
Hello from MrBillDoesMath!
Answer:
The first marker is labeled 208708; the second (consecutive) one 208709
Discussion:
Call the first mile marker "m". Then
m + (m+1) = 417417 => combine like terms
2m + 1 = 417417 => subtract 1 from both sides
2m = 417416 => divide both sides by 2
m = 417416/2 = 208708
Note: m and (m+1) are consecutive as they immediately follow each other in the set of integers.
Thank you,
MrB
