A bag contains blue marbles and red marbles, 107 in total. The number of blue marbles is 7 more than 4 times the number of red m

Alecsey [184]

Answer: blue= 93.625

Step-by-step explanation:

Let the red ball be y

Four times of red is 4y

And blue is seven times of red which means 7(4y)

4y+7(4y)=107

Open the bracket

4y+28y=107

32y=107

y=107/32

Make y the subject of formula

y=3.34

Therefore,blue is

7(4(3.34))

Blue= 93.625
