Answer:

5.79 feet

Step-by-step explanation:

Let us represent

First piece = x

Second piece = y

Third piece = z

Sac had a rope that was 15 feet long.

x + y + z = 15

He cut it into three pieces.

The first piece was 3.57 feet longer than the second piece.

x = 3.57 + y

The third piece was 2.97 feet longer than the second piece.

z = 2.97 + y

How long was the third piece of rope?

x + y + z = 15

3.57 + y + y + 2.97 + y = 15

3y + 6.54 = 15

3y = 15 - 6.54

3y = 8.46

y = 8.46/3

y = 2.82 feet

Therefore, the length of the third piece z = 2.97 + y

z = 2.82 + 2.97

z = 5.79 feet

Solve the system by elimination

Alja [10]

First of all we will eliminate x from our equations. In order to do that we will use our first and second equation and then we will use second and third equation.

$-2x+2y+3z=0...(1)\\-2x-y+z=-3....(2)$

Upon subtracting 2 equation from 1 we will get,

$3y+2z=3....(4)$

Now we will use second and third equation to eliminate x.

$-2x-y+z=-3....(2)\\2x+3y+3z=5....(3)$

Adding 2nd and 3rd equation we will get,

$2y+4z=2....(5)$

Now we will find out y from our 4th and 5th equation.

$2*(3y+2z)=2*3....(4)\\2y+4z=2....(5)$

Upon subtracting 5th equation from 4th equation we will get,

$4y=4\\y=1$

Now let us find out z by substituting y's value in 5th equation.

$2*1+4z=2\\4z=2-2\\z=0$

Now we will find x from by substituting y and z's value in equation 1.

$-2x+2*1+3*0=0\\-2x+2=0\\2=2x\\x=1$

Therefore, x=1, y=1 and z=0 is the solution of the given system.

Assume a profitable economic well produces an average income of $23 million, while the average cost of a dry hole is $1.2 millio

bezimeni [28]

The most appropriate choice for revenue and profit will be given by-

Profit expected from a 100-well drilling program = $ $146.2$

What is revenue and profit?

Total income generated by sale of goods and service is called revenue.

If $p$ is the cost of producing one unit of a commodity and $q$ is the number of units of the commodity, then the product of $p$ and $q$ gives the revenue.

If the revenue obtained by selling a commodity is more than the cost, difference between revenue and cost gives the profit.

Here,

Number of economic wells = 11

An economic well produces an average income of $23

Revenue obtained = $ $$$ $(23 \times 11)$

Number of dry wells = $100 - 11$

= $89$

Average cost of a dry hole is $1.2 million

Cost of 89 dry holes = $ $$$ $(89 \times 1.2)$

= $ $106.8$

Profit = Revenue - cost

= $ $(253-106.8)$

= $ $146.2$

Profit expected from a 100-well drilling program = $ $146.2$

Solve the following equation. 3(2x - 4) = 4(x + 1) x=?

mrs_skeptik [129]

Answer:

$x=8$

Step-by-step explanation:

$3\left(2x-4\right)=4\left(x+1\right)$

Expand:

$3\times 2x-3\times 4=4x+4\times 1$

$6x-12=4x+4$

Add 12 to both sides:

$6x-12+12=4x+4+12$

$6x=4x+16$

Subtract 4x from both sides:

$6x-4x=4x+16-4x$

$2x=16$

Divide both sides by 2:

$\frac{2x}{2}=\frac{16}{2}$

$x=8$
