Given equation : y=5/2x.
Solution: In order to graph direct variation equation, we need to make a table of different values of x and y.
We need to plug some values of x's in equation to get values of y's.
Because, we have fraction 5/2, and 2 in denominator. So it would be better to take multiples of 2, so that we don't get values in decimals.
Let us take x=0 first.
Plugging x=0 in given equation, we get
y=5/2x = 5/2(0) = 0.
Let us take x=2 first.
Plugging x=2 in given equation, we get
y=5/2 *(2) = 5
Let us take x=2 first.
Plugging x=4 in given equation, we get
y=5/2 *(4) = 5 *2 = 10.
We got three coordinates for the graph (0,0) , (2,5) and (4, 10).
Let us plot those coordinates on the graph and join the points to draw a straight line.
Answer: 10?
Step-by-step explanation:
I'm guessing the problem based off your description
5 (1/2) x 4 = X
2.5 x 4 = X
X = 10
Answer:

Step-by-step explanation:
Given the following question:

When x is the numerator of the fraction you multiply each side by the denominator in order to isolate the variable.




Hope this helps.
First lets convert feet to miles: if 1 mi = 5280 feet then 7200 feet / 5280 feet = 1.364 miles. Now we need to see how much degrees does the boiling point for water decreases: if 1 mile = 5 degrees Celsius, then 0.364 miles correspond to 0.364*5=1.82 degrees Celsius. So now we add the two values: 5+1.82 = 6.82 degrees Celsius. Now we find the decrease in the boiling point of water: 100-6.82 = 93.18 degrees Celsius. So at 7200 feet above sea level, in Santa Fe, the water boils at 93.18 degrees Celsius.
