Answer:

There are 130 m&m's in a bag. there are half as many green as red. the number of blue is equal to the number of red and gree
AleksandrR [38]
Let x = red
Let 0.5x = green
Let (x) + (0.5x) = 1.5x = blue
Let 0.5(1.5x) = 0.75x = yellow
Let 0.75x + 4 = brown

(x) + (0.5x) + (1.5x) + (0.75x) + (0.75 + 4) = 130
x + 0.5x+ 1.5x + 0.75x + 0.75 + 4 = 130
4.5x + 4 = 130
4.5x = 126
x = 28

Use this value to calculate the other required numbers.
red = 28
green = 0.5x = 0.5(28) = 14
blue = 1.5x = 1.5(28) = 42
yellow = 0.75x = 0.75(28) = 21
brown = 0.75x + 4 = 0.75(28) + 4 = 25
