In order to solve this kind of problem, we must find the difference between two negative numbers describing elevation. Although when you have 2 negative numbers in a subtraction-elevation problem, the elevation difference won't be negative... It would be positive. -56 - (-14) would usually equal -42 feet but that would just describe a regular negative subtraction problem, so it becomes 42 feet. This answer is positive since it describe the distance between these integers.
Based on the distance travelled and the time taken, the speed of the train was <u>150 km/h</u>
Speed can be calculated by the formula:
<em>= Distance / Time </em>
Distance = 600 km
Time = 4 hours
Solving will give:
= 600 / 4
= 150 km/ h
In conclusion, the train was going at 150 km/h

width = 5.5 feet and
length = 8 feet
Step-by-step explanation:
Given:
Let Width = w
then length = 2.5 + w
Area = 44.8 square feet
Required:
Find length and Width
Formula:
Putting values to find length and width
So, value of w = 5.5 and -8.1
Since width can't be negative so,
Width = w = 5.5
Length = 2.5+w = 2.5+5.5 = 8
So, width = 5.5 feet and
length = 8 feet

Answer:
y = 32
Step-by-step explanation:
32 x 2 = 64
First add all the numbers together to get the total number of marbles which would be 12 then make a fraction 3/12. Which can be simplified to 1/4 which if needed can be changed to a percentage of 25%. So your answer is either 1/4 or 25% depending on how your teacher would like it written.
