x = 3
Answer: 3cm
Step-by-step explanation:
lets say
Red bricks = 5x
<span>Gray bricks = 2x </span>
<span>5x + 2x = 175 </span>
<span>7x = 175 </span>
<span>x = 175/7 </span>
<span>x = 25 </span>
<span>Red bricks =(5x) = 5 * 25 = 125 </span>
<span>Gray bricks =(2x) = 2* 25 = 50 </span>
Since negative 1 is negative, we multiply by 1 and make it negative. Therefore, if the integer is x, the product of that and negative 1 is -1*x=-x
