First, set up variables for each runner to calculate the time:
x = faster runner
x + 0.5 = slower runner
Next, set up an equation:
9x = 6(x + 0.5)
9x = 6x + 3
3x = 3
x = 1
Since both of the runners are starting at the same place and running on the same trail, they will run the same distance. They both ran 1 mile.
Answer:
84
Step-by-step explanation:
reach triangle area is 1/2bh so
1/2(6)(4) = 12
there are 4 of them so
12x 4 = 48
then the square is 6x6 = 36
add the square to the triangle totals
48+38 = 84
Answer:
2.47
Step-by-step explanation:
all you have to do divide 9.88 into 4 and that gives you 2.47
Answer:
The total area is 45
Step-by-step explanation:
It's basically the same steps at the last problem
-19, -12, 1/2, 1, 5, 12 ----> least to greatest
12, 5, 1, 1/2, -12, -19 ----> greatest to least
Do the same as the last one, starting with the largest negative number, and ending with the largest positive number. The only difference in this case is that it is greatest to least. I tend to go from least to greatest first and then flip it around to get greatest to least (:
