Given that Jessica is a custodian at Oracle Arena.
She waxes 20 square meters space of the floor in 5/3 of an hour. Jessica waxes the floor at a constant rate means rate will remain fixed for any hour.
Now we have to find about how many square meters can she wax per hour.
To find that we just need to divide 20 squaer meters by 5/3 hours



=12
Hence final answer is 12 square meters can she wax per hour.
Which can also be written as
per hour.

Step-by-step explanation:
During the 9 mile hike he spends 2 periods of half hour swimming = 1 hour.
actual hiking time = 3*3 = 9 hours
So total time = 9+1 = 10 hours
Let's call the first unknown integer x and the second one y.
"Four times an unknown integer"
"Multiplied by three times the unknown integer plus a different unknown integer"
- 4x is multiplied by 3x+y, so 4x(3x+y)=12x²+4xy
"Equals 100."
And so the answer is C: 12x²+4xy-100=0
