A jetliner uses 3,600 gallons of fuel per hour while it is cruising, and there are 15,000 gallons of fuel in the jetliner's fuel

coldgirl [10]

The equation to represent the relationship between x and y is y = 15 - 3.6x .

In the question ,

it is given that

fuel used by jetliner per hour = 3600 gallons

fuel available in the jetliner = 15000 gallons

Given that y represents the amount of fuel remaining in the tank after x hrs.

As the unit of y is in thousands of gallon

So , according to the question

the equation becomes ,

y = 15 - 3.6x

For plotting the graph

Substitute x= 1hr , y = 11.4 , (1,11.4)

x = 2 , so y = 7.8 , (2, 7.8)

x = 3 , so y = 4.2 , (3,4.2)

x = 4 , so y = 0.6 , (4,0.6)

Therefore , the equation is y = 15 - 3.6x , the graph of the equation is drawn below .

Olympia ate lunch at a restaurant. The amount of her check was $6.89. She left $8.00 on the table, which included the amount she

Leno4ka [110]

Answer:

not sure if the answer is obvious but I'd say $6.89 + t = $8.00

Step-by-step explanation:

so to make it more understandable you have to first go over the question and ask your self is the tip included in the totally amount owed or is it apart

after you figure out that its apart all you have to do is plug in the numbers you could verify this by checking every equation like this

$6.89 + t = $8.00 (t) in this case is the tip which would be $1.11 all you do to arrive at that answer is subtract the amout owed from the amount given like this $8.00 - $6.89 = $1.11 which will be your tip

now continue checking your answer next is , $6.89 - t = $8.00

which would be $6.89- $1.11 = $5.78 not quite right because now she is short on the pay , on to the next its $6.89t= $8.00 which would be $6.89 x $1.11= $7.65 rounded to neartest tenth which would included the amount but not all the tip given meaning tip would be short 0.35 cents and finally $6.89= $8.00 divided by t , now this takes the amount give which is $8.00 and divides by t which is $1.11 doing this $6.89 = $8.00/$1.11 which it is trying to imply that $6.89 is equal to $7.21 which would be incorrect making the only reasonable equation $6.89 + t = $8.00 reaveling that the tip given was $1.11

hopefully that help maybe i can get brainlist?!
