Let x represent the number of red marbles, then blue marbles are represented by x + 31

red +  blue  = 225

x    +  x + 31  =  225

2x + 31 = 225

2x = 194

 x = 97

Blue: x + 31 = 97 + 31  = 128

Answer: 128 blue marbles

225-35=194/2 because there is two colors red and blue you divide it and then answer is 97 and then you add  35+97=132 so there are 132 blue marbles

Dmitriy789 [7]

Answer

Find out the how many games did the teams lose .

To prove

Formula

Percentage = \frac{Part\ value\times 100}{Total\ values}

As given

Salem High School's winter sports teams WON 72% of their games last season.

If the teams played 50 games .

Percentage = 72%

Total value = 50

Put in the formula

72 = \frac{Number\ of\ games\ win\times 100}{50}

Number\ of\ games\ win = \frac{72\times 50}{100}

Number of games win = 36

Number of  games teams loses = Total number of games - number of games win

                                                          = 50 - 36

                                                          = 14

Therefore the number of games  team loses are 14 .
