Answer:
AC = 22
Step-by-step explanation:
Given that B is the midpoint of AC , then AB = BC , that is
2x + 1 = 5x - 14 ( subtract 2x from both sides )
1 = 3x - 14 ( add 14 to both sides )
15 = 3x ( divide both sides by 3 )
5 = x
Thus
AC = AB + BC = 2x + 1 + 5x - 14 = 7x - 13 = 7(5) - 13 = 35 - 13 = 22
Answer:
32.75
Step-by-step explanation:

0.75 lbs + 32 lbs = 32.75 lbs
Answer:
X=5
y=2
Step-by-step explanation:
x+4y=13
5+4(2)=13
x-y=3
5-2=3
The right answer is Option E: 10 cars
Step-by-step explanation:
Given,
Length of railroad car = 6 inches
The length of railroad track = 5 feet
We will convert this length into inches.
1 feet = 12 inches
5 feet = 12*5 = 60 inches
Let,
x be the number of cars.
Number of cars * Length of each car = Length of track
![6*x=60\\6x=60](https://tex.z-dn.net/?f=6%2Ax%3D60%5C%5C6x%3D60)
Dividing both sides by 6
![\frac{6x}{6}=\frac{60}{6}\\x=10](https://tex.z-dn.net/?f=%5Cfrac%7B6x%7D%7B6%7D%3D%5Cfrac%7B60%7D%7B6%7D%5C%5Cx%3D10)
10 cars can fit on railroad track.
The right answer is Option E: 10 cars
