Step-by-step explanation:
It says that the buildings together are 200 meters high and from the top pf the first to bottom of the second is 20(whole building) but from the top of the first to second is 10 (half of the building ) so if the degree if half the high will be half too so the high will be 200/2 = 100 meters high for each buildings :))

Answer: 60
Step-by-step explanation: 1/4 of 96 is 24 so you subtract that and get 72. And 1/6 of 72 is 12 and you subtract that leaving you with 60 to remain.
5x -2 = 63
<u> +2 = +2 (add 2 to both sides)</u>
<u>5x = 65 (your equation)</u>
5 5 (divide both sides by 5)
x = 13
