Ok if you would to take away 3 it would increase the mean median and mode
6x + 4y = -24
30x + 20y = -120
You can multiply all of the numbers by any common factor and get an equation that works.
B is the right answer because you can set up a ratio like this:
If you solve for A, then you get:
Hopefully this makes sense. Also, in the textbox,
∠A = 45°
and your answer's B.
To get Andy’s descent as a unit rate, we can express this
in terms of ratio of distance over time.
The total distance he descended is 10 feet while the
total time 2 ½ minutes or 2.5 minutes. Therefore his rate is:
rate = 10 feet / 2.5 minutes
rate = 4 feet / minute
Answer: 192 or -40
It's definitely one of those
Hope this helps :)
