The answer would be -1. just mark -1 on the number line
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 :))
i hope this is helpful
have a nice day
You divide you total tickets by 2. so you would take 20 and divide it by 2= $10 for 20 tickets. So the rule is divide the total number of tickets by 2.
It means 1.8 × 10 to the tenth power. the E is a ten are you working with scientific notation
