What is the actual length of the train car?
A.21.6 ft
B.27 ft
C.43.2 ft
D54 ft
Answer: c
Step-by-step explanation:
The required actual length of the train is given as 27 ft.
Given that,
Heather drew the scaled drawing of a train car shown below. She used the scale of 2 cm = 5 ft to complete the drawing.
The scale factor is defined as the ratio of the modified change in length to the original length.
here,
As given,
2 cm = 5 ft
1 cm = 5/2 ft
Tain car length = 10.8 m
Actual length = 10.8 × 5/2 = 27 ft
Thus, the required actual length of the train is given as 27 ft.

2x+y=21;y=-2x+21
please hurry I need this straight away
Step-by-step explanation:
2x + y = 21
Solving
2x + y = 21
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-1y' to each side of the equation.
2x + y + -1y = 21 + -1y
Combine like terms: y + -1y = 0
2x + 0 = 21 + -1y
2x = 21 + -1y
Divide each side by '2'.
x = 10.5 + -0.5y
Simplifying
x = 10.5 + -0.5y
