Amarble weighs 9 grams. a bag of marbles weighs 594 grams. if the bag has an equal number of red and green marbles, how many red marbles are in the bag? a)28
b) 33
c)56
d)66

Number of red marbles  = 33

Step-by-step explanation:

Weight of a marble  = 9 grams

Weight of bag of marbles = 594 grams

To find : Number of red marbles in a bag

Given that the bag has an equal number of red and green marbles, so

let number of red marbles = number of green marbles = x

Now, number of marbles in a bag = Weight of bag of marbles / Weight of a marble = 594 / 9 = 66

According to question ,

x + x = 66

2 x = 66

x =

So, number of red marbles = x = 33

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

the answer is (-4,-4)

hope this ! : d
