The total weight of all the students in Mrs. Jones’s math class is 2,808
lbs. The mean weight is 140 lbs., rounded to the nearest whole pound.
How many students are in the class?

step-by-step explanation:

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6

c=x-39/5

x=39/5+c
