Answer:
1575 ft
Step-by-step explanation:
Convert 1/10 to decimal to make the math simpler.
1/10 = 0.1
Divide 3.5 by 0.1.
3.5/0.1 = 35
Multiply 35 by 45.
35 × 45 = 1575
The train will travel 1575 feet in 3.5 seconds.
1- 192
2-36
1- 168(original altitude)
+360(because the question says the hill is ______ 360 feet higher than checkpoint 2)
192
2- 168(checkpoint 2)
-132( checkpoint 4)
______
036
x+y = 652
x-3y=0
need to enter those into a graphing calculator to get the answers
x=489 ( games)
y=163 ( system)
them check 163*3 = 489 and 489+163 = 652
