Suppose that the weight (in pounds) of an airplane is a linear function of the amount of fuel (in gallons) in its tank. When car

rying 10 gallons of fuel, the airplane weighs 2064 pounds. When carrying 45 gallons of fuel, it weighs 2288 pounds. How much does the airplane weigh if it is carrying 60 gallons of fuel?

Answer:

Now, to answer the question, we need to add the weight of (58-42) = 16 gallons of fuel to the weight of the plane

carrying 42 gallons of fuel, 2331 pounds.

So, the answer is 2331 + 16*5.5 = 2419 pounds.

find the solution to the system. write your solution as an ordered pair (x,y) with no spaces, no solution or infinitely many 2x-
Kitty [74]

Answer:

(-8,4)

Step-by-step explanation:

Given: 2x-3y=-28 and x+6y=16

solve for a variable and then substitute back into other equation

x + 6y = 16

x = 16 - 6y; now use this in the other equation

2x - 3y = -28; substitute into x

2(16 - 6y) - 3y = -28; distribute 2

32 - 12y - 3y = -28; combine y's

32 - 15y = -28; isolate 15y

32 + 28 = 15y; add the numbers

60 = 15y; divide by 15

y = 4

Now use this to plug into other equation

x + 6y = 16; y=4

x + 6(4) = 16;

x + 24 = 16; subtract 24 from both sides

x = -8

To find:

The selling price of the shirt before the sl;e

Explanation:

Let the old price be x.

The equation can be framed as follows,

\begin{gathered} (\frac{100-25}{100})\times x=20.99 \\ \frac{75}{100}\times x=20.99 \\ x=20.99\times\frac{100}{75} \\ x=27.986 \\ x\approx27.99 \end{gathered}

Final answer:

The selling price of the shirt before the sale is $27.99.
