Red and gray bricks were used to build a decorative wall. The number of red bricks number of gray bricks was 5/2 . There were 175 bricks used in all how many gray bricks were used?(1 point)

Answer 1

Let's say the number of gray bricks used is G.
Since the ratio of red bricks to gray bricks is 5/2, the number of red bricks used is (5/2) * G = 5G/2.
The total number of bricks used is the sum of red and gray bricks which is G + 5G/2 = 175.
Multiplying throughout by 2 to get rid of the fraction gives 2G + 5G = 350.
Combining like terms gives 7G = 350.
Dividing both sides by 7 gives G = 350/7 = <<350/7=50>>50.
Therefore, 50 gray bricks were used. Answer: \boxed{50}.
