The sum of the heights of two high-rises is x feet. If the second high rise is 37 feet taller than the first, how tall will the first high rise be after they add an antenna with a height of z feet to the top?  Select:
A) (x+z)/2 + 37	B) 2x−(37+z)	C) (x−37)/2 + z	D) x/2 - 37 + z	E) (2x−37)/z
I will note h1 the height of high-rise 1 and h2 the height of high-rise 2. SO:   h1 + h2 = x   and h2 = h1 + 37 =&gt;   Q: h1+ z = ?   h21+ h1 + 37 = x =&gt; 2h1= x-37 =? h1 = (x-37)/2   =&gt; h1+ z = (x-37)/2 + z, (x−37)/2 + zORRE(x−37)/2 + zT ANSWER (x−37)/2 + z
