The temperature changed a total of 14° over the course of 7 hours with an average change of 2° per hour drop.
Answer:
Infinitely many solutions
Step-by-step explanation:
-5.9x - 3.7y = -2.1
5.9x + 3.7y = 2.1
If we add these two equations together, -5.9x cancels out 5.9x, -3.7y cancels out 3.7y, and -2.1 cancels out 2.1.
This leaves us with:
0 = 0
Since this is true, that means there are infinite solutions.
Multiply it out
x^2 + 4x -8x -32
Combine like terms
x^2 -4x - 32
Patty because she has the lowest time out of them all. From least to greatest Patty would be the least with her time being shorter than the rest
ANSWER: 3,520 yards = 2 miles.
440 yds is 1/8. Multiply 440 by 8 to get the full distance. Hope this helps! :)
