Plz open this power point and help me

ANSWER: Company C

EXPLANATION:

1) Find the least common multiple of 6, 10 and 12. This would be 60 because:

6 x 10 = 60

10 x 6 = 60

12 x 5 = 60

2) Now you can figure out how much money each company gives for every $60 worth of gift wrap by multiplying the amount they gave in the paragraph by the same as what you did in the calculations above.

Company A

$1 x 10 = $10 for every $60 worth of gift wrap sold

Company B

$2 x 6 = $12 for every $60 worth of gift wrap sold

Company C

$3 x 5 = $15 for every $60 worth of gift wrap sold

ARGUMENT

Company C should be selected because they give the most money per dollar ($15 per $60 worth of gift wrap sold).

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
