Mrs. Wilkinson's grandchildren are participating in a gift wrap sale to raise money for their
school. She decided to stock up, so she ordered 1 roll of reversible paper and 2 rolls of
metallic paper from Michelle, spending a total of $36. She also ordered 4 rolls of reversible
paper and 4 rolls of metallic paper from Ellie, which cost a total of $100. Assuming that rolls
of each type are priced the same, what is the price for each kind of paper?

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
