Please Help ASAP! I suck at geometry :(
ZanzabumX [31]

We know that for every 5 red bricks there were 2 gray bricks.

The total amount of red bricks and grey bricks in this sample is 7.

5 red bricks + 2 grey bricks = 7 bricks

Now, we divide 175 "total number of bricks used" by 7 "5 red bricks + 2 grey bricks = 7 bricks" and we will get a quotient of 25.

Now we know that 25 bricks is \frac{1}{7} of the wall. The gray bricks are \frac{2}{7} so we can multiply 25 by 2 and we will get a product of 50. If 1/7 = 25 grey bricks so 2/7 would be the grey bricks.

175 - 50 = number of red bricks.

Therefore, there were 125 red bricks.
