Red and gray bricks were used to build a decorative wall. The number of red bricks and the number of gray bricks was five over 2 . There were 175 bricks used in all. How many red bricks were used? (1 point) Responses 25 25 125 125 50 50 35

Let the number of red bricks used be x.

The number of gray bricks used is also x.
So, the total number of bricks used is x+x=2x.
According to the given information, 2x=175.
So, x=175/2=<<175/2=87.5>>87.5.
Since we can't have half a brick, the number of red bricks used is 87. This corresponds to option 50.
