Nancy started the year with $425 in the bank and is saving $25 cach week. Sam started the year with $705 but is spending $15 a week. Write a system of equations that model the following situation Define each variables with a "Let" statement, write two equations, and solve completely
Let 3 =
Let y =
Nancy:
Sam:

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

the k side

38 was the other number of your question.

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
