Step-by-step explanation:
Given : There are a total of 64 students in a drama club and a yearbook club. The drama club has 10 more students than the yearbook club.
To find : Write a system of linear equations that represents the situation.
Solution :
Let x represent the number of students in the drama club
and y represent the number of students in the yearbook club.
There are a total of 64 students in a drama club and a yearbook club.
i.e. ....(1)
The drama club has 10 more students than the yearbook club.
i.e. ....(2)
Substitute the value of (2) in (1),
Substitute in (2),
Therefore, the system of equations are and
Answer:
911,690.
Step-by-step explanation:
Please consider the complete question.
A city has a population of 390,000 people. Suppose that each year the population grows by 6.75%. What will the population be after 13 years? Round your answer the nearest whole number.
We will use exponential growth formula to solve our given problem.
, where,
y = Final value,
a = Initial value,
r = Growth rate in decimal form,
To find the population after 13 years, we will substitute in population growth equation as:
Upon rounding to nearest whole number, we will get:
Therefore, the population of the city after 13 years would be 911,690.
0.2(6x+1)/3.6=0.5x/9
Solution
(1.2x + 0.2)/3.6 = 0.5x/9
Cross multiplying, we get
9(1.2x + 0.2) = 3.6 * 0.5x
10.8x + 1.8 = 1.8x
10.8x - 1,8x = -1.8
9x = -1.8
Dividing both sides by 9, we get
x = - 0.2
That's the answer.
Thank you.
