Very interesting wording but from what I gathered, scaling down by a factor of 1/10 would be 64- 6.4(1/10 of 64) so your final answer would be 57.6
Hope this explanation helps ;)
ANSWER
The constant of proportionality is 24.
EXPLANATION
If the volume of a box (V) varies directly with it's length (l), then we can write the mathematical statement,
We introduce the constant of proportionality k, and write the equation,
When V=288, l=12.
We substitute these values to obtain;
Divide both sides by 12,
Part A:
90.10 = 0.30x + 55
Part B:
Subtract 55 from both sides
90.10 = 0.30x + 55
-55 -55
__________________
35.10 = 0.30x
Next, you need to isolate the variable so you must divide both sides by 0.30. You should get:
117 = x
Vin sent 117 text messages that month.
Part C: (this part is a bit unclear, though I will try to answer it as best I can)
I found the number of text messages Vin sent in the month of October by creating an equation that outlined his bill and solving it.
Here is the correct answer
Answer:
132x-8
Step-by-step explanation:
I think I might be wrong, but hopefully this is helpful, and yet I still find this confusing.
It's a simplification I don't know if you needed that.
