Solve egch problem by writing and solving an equation,
seki and raina sold a total of 152 candles for their school fund-raiser. if seki sold three boxes of candles and
raina sold two boxes plus twelve single candles, how many candles come in each box?
(
3-25 + 12 = 162, b = 150
3 - 2 + 12 = 162,6 =30
they
3*20-12- 162, b = 35
3+2+12= 162,5=35

table 3 represents a direct variation function. : )

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
