Answer:

Step-by-step explanation:

Let's solve one of them for x.

Add 4

Divide by 3.

Now, plug the value of y in the formula, or you can plug the value of x in the other equation. I'll take this one.




Multiply by 3 to get rid of the denominator.

add x

Combine like terms;

Divide by 4.

Simplify.

Now that you found the value of x, replace it in any of the equations to find y.

It's 1/2,-2 just did the math.
Answer: 2nd most popular country = 15895 students
most popular country = 24390 students
Step-by-step explanation:
Total students: 40,285
2nd most popular country = x students
most popular country = x + 8,495 students
x + x + 8495 = 40285
2x + 8495 = 40285
2x = 40285 - 8495
2x = 31790
x = 15895
2nd most popular country = x = 15895 students
most popular country = x + 8,495 = 15895 + 8,495 = 24390 students
5x+30- 2x+9
3x+39 is the expression.

Step-by-step explanation:
The formula for finding the area of a circle is;

Where (
) represents the area of the circle, (
) represents the value (
) and (
) represents the radius of the circle. As per its definition, the diameter is the largest cord or line segment that can be drawn through a circle, the diameter always passes through the center of a circle. The radius ( a line segment that can be drawn from the center of the circle to any side of the circle) is always half of the diameter.
This means that the radius for the given circle is (
), since (
÷
)
Substitute these values into the equation and solve for the area of the circle.
