Answer:
(2, -8)
Step-by-step explanation:
The answer is (2, -8) because when you reflect a point across the x-axis, the x-coordinate always remains the same, but the y-coordinate will change. In other words, the y-coordinate becomes the opposite (signs change). In this case, since the y-coordinate was positive 8, when you reflect the point across the x-axis, the y-coordinate will change to -8
Let
x--------> amount of erasers that Sari has
y--------> amount of erasers that Sam has
we know that
-------> equation 
-----> equation 
Substitute equation in equation
![[3y]+y=28\\ 4y=28\\ y=28/4\\ y=7](https://tex.z-dn.net/?f=%20%5B3y%5D%2By%3D28%5C%5C%204y%3D28%5C%5C%20y%3D28%2F4%5C%5C%20y%3D7%20)
find the value of x
therefore
the answer is
Sari has 
erasers
Answer: B), C), and E)
Explanation for B:
This is one of the correct statements because to simplify the fraction into decimal form you would need to divide the numerator by the denominator, which in this case; 35 is the numerator and 40 is the denominator. Therefore divide 35 by 40 is a correct statement.
Explanation for C:
This is another correct statement because when you actually divide the number 35 from 40 into a decimal, you end up with the value 0.875.
Explanation for E:
Another correct statement. In decimal form, the fraction 35/40 terminates, meaning it does not go on forever, and it also does not repeat forever. When a decimal does not terminate or repeat, it is considered a rational number. Since the decimal 0.875 does neither, it is also considered a rational number.

Write a proporion:
Answer: option A
Answer:
Step-by-step explanation:
The circumference is the distance around a complete circle: in essence, the perimeter of a circle. The formula to find the circumference of a circle is the following:
Where (d) represents the diameter, the largest cord that can be drawn in a circle, it goes from one end to another, passing through the center of the circle. The parameter (
) represents the number (3.1415...). However, one is given a semicircle, thus one must divide the result in two, and then add the value of the diameter to find the perimeter of the given object. Therefore the equation for the circumference of this circle is as follows:
Substitute in the given value,
Simplify,
