1) substitute 10x in for the equation.
There are a total of 2,000 students in the school.
1.) There are 540 students in the 6th grade. 540 is only 27% of students compared to the total. To find the total students in the whole school, we divide 540 by 27%.
2.) We first change 27% into a decimal by moving the point two times to the left. (Rule to change the percent into a decimal)
27% = .27
3.) Before we divide, we remove the decimal by moving the decimal two times to the right and so do we to 540.
.27 = 27
540. = 54000.
4.) Now we have 54000 divided by 27 which give us the answer of 2,000.

The answer is A 5^11 I hope that's right
Answer:
(3x+5y)/8
Step-by-step explanation:
The total amount is 150+250=400
We then do (3x+5y)/2 × 1/400
This equals (3x+5y)/800
We multiply that by 100 giving us the final answer.
Answer:
This number can be found using the Rule of 70, which describes the formula dt = 70 / r, where dt is the doubling time, and r is the annual rate of growth.
Step-by-step explanation:
24/6 = 4
20 x 2 = 40 x 2 = 80 x 2 = 160 x 2 = 320
20 ---> 320 in the first day.
Keep doing this equation. Multiply each day's end result by 2 four times for 9 more days.
