Let the cost of the toy train be x.
Toy Train = x
Toy car = 2x - 20
Construct equation :
The toy car costs $100.
⇒ 2x - 20 = 100
Solve x :
2x - 20 = 100
2x = 100 + 20
2x = 120
x = 60
Find the cost of the toy train :
Cost of the toy train = x = $60
The toy train costs $60.

C and E
Step-by-step explanation:
The plane starts at 32,460 feet.
It then ascends 1645 feet. Ascending means it's going up higher. So we add.
32,460 + 1645 = 34,105 (C)
From here (34,105 feet) the plane descends by 3/5 of it's height. Descending means it's lowering. So we subtract.
But first we have to figure out how much we are subtracting.
3/5 is equal to .6
Multiply to find 3/5 of current height.
34,105 × .6 = 20,463
So the plane descends by 20,463 feet.
34,105 - 20,463 = 13,642 feet (E)
