K/11 = 7
multiply 11 to both sides
K/11 (11) = 7(11)
multiply 7 and eleven together
K = 7(11)
Answer
K = 77
77 is your answer
hope this helps
Answer:
In the most popular abroad country: 29,255 students
In the second-most one: 20,872 students
Step-by-step explanation:
Let's write the situation in an equation to help us solve this. X represents the amount of students in the second most popular country. So we know that in total, there's 50,127 students so let's make an equation that equals this. ???????=50,127. As we know, the most popular country has 8383 more students than the second one so we can write it as x+8383 and for the second most popular country, we can write it as x. We know that both of the countries students combined equal 50,127 students so we have our equation. (x)+(x+8383)=50,127 students. After solving the equation, you get x=20, 872. As we know x=the amount of students in the second most popular country which means there's 20,872 students in the second one. Additionally, for the first most popular one, the equation for the amount of students in it is x+8383 so..... 20,872+8383=Total number of students in the most popular one which is 29,255 students.

Step-by-step explanation:
You want to calculate the interest on $550 at 2.1% interest per year after 4 years.
The formula we'll use for this is the simple interest formula, or:
I = P x r x t
P is the principal amount, $550.00.
r is the interest rate, 2.1% per year, or in decimal form, 2.1/100=0.021.
t is the time involved, 4 years.
So, t is 4 year time periods.
To find the simple interest, we multiply 550 × 0.021 × 4 to get that:
The interest is: $46.20
