Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels 14 miles per hour slower than the westbound train. If the two trains are 480 miles apart after 3 hours, what is the rate of the eastbound train?
73 is the rate of the eastbound train while The speed of the westbound train is 59 miles per hour.
What is Speed?speed is described as. the pace at which an object's location changes in any direction. Speed is defined as the distance traveled divided by the travel time. Speed is a scalar quantity because it just has a direction and no magnitude.
Given, Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels 14 miles per hour slower than the westbound train.
Eastbound train:
time = 3 hrs, rate = x mph, distance = 3x miles
Westbound train:
time = 3 hrs ; rate = x-14 ; distance = 3x-42 miles
3x + 3x - 42 = 480
6x = 438
x = 73 (rate of the eastbound train)
To find the rate of the westbound train:
rate = x -14
rate = 73 - 14
rate of westbound train = 59
Therefore, The speed of the westbound train is 59 miles per hour.

A chemical manufacturer wants to lease a fleet of 26 railroad tank cars with a combined carrying capacity of 560,000 gallons. Tank cars with three different carrying capacities are available: 7,000 gallons, 14,000 gallons, and 28,000 gallons. How many of each type of tank car should be leased?
Answer:
16 of the 28,000 gallon tanks
6 of the 14,000 gallon tanks
4 of the 7000 gallon tanks
Step-by-step explanation:
ez
The tank should be leased by each quantity by 4 tank cars of 7000 gallons , 6 tank cars of 14000 gallons and 16 tank cars of 28000 gallons .
What is elimination method?In the elimination method, we eliminate any one of the variables by using basic arithmetic operations and then simplify the equation to find the value of the other variable. Then we can put that value in any of the equations to find the value of the variable eliminated.
According to the question
Let Tank cars of 7000 gallons = x
Let Tank cars of 14000 gallons = y
Let Tank cars of 28000 gallons = z
A chemical manufacturer wants to lease a fleet of 26 railroad tank cars with a combined carrying capacity of 560,000 gallons.
i.e ,
x + y + z = 26 ---------------------------------------(1)
and
7000x + 14000y + 28000z = 560000
x + 2y + 4z = 80 --------------------------------(2)
Now , solving equation (1) and (2) by elimination method
x = 4
y = 6
z = 16
Hence, The tank should be leased by each quantity by 4 tank cars of 7000 gallons , 6 tank cars of 14000 gallons and 16 tank cars of 28000 gallons .

(3x + 23) degree (7x - 37) degree find m angle XYV
Answer:
An Obtuse angle is an angle whose degree measure is greater than 90 and less than 180o. ... 2x + 8 + 3x + 2 = 180 ... 14 – 23, Provide the name of the following relationships: 14. ... m∠BEC = 5x - 25 and m∠DEA = 7x – 65, find ... 37. If the measures of the angles of a triangle are represented by 2x + 8, x - 8 and 2x – 20.
Step-by-step explanation:
The required measure of angle ∠XYV is given as 112°.
What are the angle?Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.
here,
According to the given condition,
As Line WV intersects line XZ at V so,
Angle XYW = Angle VYZ
Substitute the value in the above expression,
3x + 23 = 7x - 37
60 = 4x
x = 15
∠ XYW = 3x + 23
= 3(15) + 23
= 45 + 23
= 68
Now,
∠XYV = 180 - ∠ XYW
Substitute the value in the above expression,
∠XYV = 180 - 68
∠XYV = 112°
Thus, the required measure of angle ∠XYV is given as 112°.
