3z because the product means multiplication so it would be 3 times z which is just 3z

<span>George And Carmen Went On A Bicycle Trip. They Took A Bus To Their Starting Point Then Biked The Rest.
They Traveled 275 Kilometers In Total,
And They Biked 55 Kilometers More Than They Were Bussed.
Let X=Kilometers Traveled By Bike
Let Y=Kilometers Traveled By Bus.
Find How Many Kilometers They Traveled By Bike.
--------
X + Y = 275 km
X = Y + 55
-------------
Substitute or X and solve for "Y":
Y+55 + Y = 275
2Y = 220
Y = 110 km (distance traveled by Bus)
-------
Solve for "X":
X = Y + 55
X = 110+55 = 165 km (distance traveled by Bike)</span>
First Part: Overall change in altitude: -88.5ft
Part C: 151.5ft
Part D: E= 240-(6.5×15)+9

Part ? because:
6.5×15= 97.5 We know that decreases. So it would be, -97.5, next it says it increases by 9ft. So -97.5+9=-88.5ft
Part C becuase: The original elevation is 240, and the elevation is subtracted by 88.5, so...
240-88.5=151.5ft
