Red and gray bricks were used to build a decorative wall. The number of red bricks number of gray bricks was 52 . There were 175 bricks used in all how many gray bricks were used?(1 point)
Let's solve this problem mathematically.
Let's assume the number of gray bricks used is x.
According to the problem, the number of red bricks is 52 more than the number of gray bricks. Therefore, the number of red bricks used is x + 52.
The total number of bricks used is 175, so we can write an equation:
x + (x + 52) = 175.
Combining like terms, we get:
2x + 52 = 175.
Subtracting 52 from both sides, we get:
2x = 123.
Dividing both sides by 2, we get:
x = 61.5.
Since we cannot have half a brick, we can conclude that 61 gray bricks were used.
