Answer:
range of scores on final exam student get B is 90 to 100
Step-by-step explanation:
given data
Psychology 101 score = 66
average of his midterm = between 78 and 90
maximum = 100 points
to find out
range of scores on final exam student get B
solution
we consider here lowest marks need in final = x
so average at two marks should be
equation is
average marks = 0.5 × ( mid term marks + final marks ) .................1
put here value
78 = 0.5 × ( 66 + x )
x = 90
and
90 = 0.5 × ( 66 + x )
x = 114
so range 90 to 114
but maximum marks is 100 so
range of scores on final exam student get B is 90 to 100

Answer: -1+6y+7x
To simplify expressions, you have to be able to combine like terms (eg. 3x and 2x to get 5x). Since there are none in this expression, and you can't combine y and x, this expression can't be simplified.
*If it helps, think of x and y as different types of candy... ;3
For example, you can't combine 12 Skittles (x) and 4 Reese's (y), because they aren't the same. So, you'd write that you have 12 Skittles and 4 Reese's.
