Answer:
Literal Equation
Step-by-step explanation:
He pays $450 in taxes.
Since the first $10,000 of the assessed value is exempt, we subtract $10,000 from the $25,000 assessed:
25000-10000=15000
Now we need to see how many $100-increments are in 15000. We do this by dividing:
15000/100 = 150
Each of these raises the taxes by $3:
150(3) = 450
Answer:
Scientist B
Step-by-step explanation:
1 kg = 2.2 lbs
1L = 2.11 pints
So let's convert Scientist B's data.
3.0lbs salt = 3.0/2.2 = 1.36kg
6 pints water = 6/2.11 = 2.84L water
Scientist A
1kg salt
3.0L water
We now figure out the concentration of salt in water.
Scientist A Scientist B
1kg/3.0L = .33kg/L 1.36kg/2.84L = .48kg/L
So scientist B had a more concentrated solution.
Denominator:
so excluded values are x = -1 and x = 1.
