Answer:
Step-by-step explanation:
20 + g = 25
-20 -20
g = 5
Y+5=2/3x(x-4) is point slope form
So, we need to figure out how much times the body size of the flea it can jump. First, we need to figure out the size of the flea: <em>2^-4=0.0625</em>
Now that we have the size of the flea, we need to figure out how high it can jump: <em>2^3=8</em>
After we figure out the size of the flea, we need to divide 8 by .0625 because it is inverse operations to multiplication: <em>8/.0625=128</em>
Answer: The flea can jump 128 times higher than it's body size.
I am thinking your answer is 78 students. You do 1/5 times 390. And I think the the part about the dog is just extra information.
