We have
3 / (x-5) - x/5
We make the GCF and we have
15/[ 5(x-5) ] - x(x-5)/[ 5(x-5)]
= [ 15 - x(x-5) ] [5(x-5)]
= [ 15 - x^2 + 5x] / [ 5 (x-5) ]
= [15 - x^2 + 5x]/[5x - 25]
An answer to your question is (15-x^2+5x)/(5x-25)
For #1
city A's mean would be 10.5, then you would divide it by the number of numbers there is which is 5,So 10.5/5 is 2.1
city B's mean would be 11.6 then you would divide it by the number of numbers there is which is 5, So 11.6/5 is 2.32.
thats all I have don't know how to do #3 sorry
Answer:
Step-by-step explanation:
"mix one cup of vinegar with one gallon of water"
1 cup = 8oz; one/4 cup = 2oz
You can see that quantity|the quantity|the number} of vinegar is 1/4 of the first amount,
so, we are going to would like 1/4 of the number of water, that is 1gallon = 128oz
so, 1/4 times 128oz = 32oz, that is one quart
Algebraically, 8oz : 128oz = 2oz : x
8x = 256; x = 32oz
