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 ?	Pick one:	A) (x+z)/2 + 37	B) 2x−(37+z)	C) (x−37)/2 + z	D) (x - 37 )/2	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 h12= h21+ 37 =&gt;   h1 + h1+ 37 = x =&gt; 2h1 = x-37 =? h1 = (x-37)/2   , CORRECT ANSWER (x - 37 )/2
