Answer: 5 benches and 23 students
Step-by-step explanation:
I will answer in English.
We have E students and B benches.
If we sit 4 students per bench, we have 3 students left.
then:
E = 4*B + 3
And if we sit 5 students per bench, there are two places with no students sited.
E = 5*B - 2
now we can replace the E in the second equation with the right part in the first equation:
4*B + 3 = 5*B - 2
3 + 2 = 5*B - 4*B
5 = B
So we have 5 benches, and:
E = 4*5 + 3 = 23 students.
30 * 11.95 = 358.5 so mr kaplan will end up paying $358.5
So, you will put the numerator inside the symbol and the 2 outside of it so like
429.5

An option that best approximates the percent decrease in consumption of wood power in the United States from 2000 to 2010 is (B) 11%.
<h3>
What is the percentage?</h3>
- A percentage is a number or ratio expressed as a fraction of 100 in mathematics.
- The percent sign, "%," is commonly used, but the abbreviations "pct.", "pct," and sometimes "pc" is also used.
- A percentage is a number with no dimensions; it has no unit of measurement.
To find an option that best approximates the percent decrease in consumption of wood power in the United States from 2000 to 2010:
- Looking at the numerical value of wood energy source in 2000, it is 2.25, while it drops to 2.00 in 2010.
- So, the percentage decrease in the value is given by:
- (2.25 - 2.00)/2.25 × 100
- 0.25./2.25 × 100
- 100/9
- 11.11
- ≈11
Therefore, an option that best approximates the percent decrease in consumption of wood power in the United States from 2000 to 2010 is (B) 11%.
