Equal because 30 is the median and when you find the mean, it is also 30. Please give brainliest!
Answer:
and 
Step-by-step explanation:
If two equations are given, we can solve one of the equation in terms of single variable and put it in the other equation which will further give the value of x and y.
For the given equations:
Equation:1
Equation:2
Solving equation multiply equation 2 with 4 on both the sides
Equation 3
Subtracting Equation:3 from Equation:1

Putting value of 'y' in Equation:2 which will give the value of x

You will have approximately $257 at the end of 8 years.
Given:
The polynomial
is divided by (x+2).
To find:
The remainder.
Solution:
Remainder theorem: If a polynomial p(x) is divided by (x-c), then the remainder is p(c).
Consider the polynomial:

It is divided by (x+2). So, by the remainder theorem the remainder is p(-2).
Substituting x=-2 in the above polynomial, we get



Therefore, the remainder is -9.
X= - x/2+9 if that is what you are asking
or -2x+18
