Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : 

   4*(2*x-6)-(10*x-6)=0 


   2x - 6  =   2 • (x - 3) 

   8 • (x - 3) - (10x - 6) = 0 

   -2x - 18  =   -2 • (x + 9) 

 -2 • (x + 9) = 0 

Solve :    -2   =  0

<span>This equation has no solution.
</span>A a non-zero constant never equals zero.

Solving a Single Variable Equation : 
 Solve  :    x+9 = 0 

<span>
 </span>Subtract  9  from both sides of the equation :<span> 
 </span>                     x = -9

The number line which line represents the solution set for the

inequality 3(8 - 4x) < 6(x - 5) is:

" A number line from negative 5 to 5 in increments of 1.

An open circle is at 3 and a bold line starts at 3 and is pointing to

the right " ⇒ 2nd answer

Step-by-step explanation:

To solve an inequality

  • Simplify each side
  • Collect the variable terms in one side and the numerical terms in other side
  • Solve to find the solution set

∵ 3(8 - 4x) < 6(x - 5)

- Simplify each side

∴ 24 - 12x < 6x - 30

- Add 12x to both sides

∴ 24 < 18x - 30

- Add 30 to both sides

∴ 54 < 18x

- Divide both sides by 18

∴ 3 < x

∴ The solution is all real numbers greater than 3

- That means a bold line started with an open circle at 3 and

   pointing to the right

The number line which line represents the solution set for the

inequality 3(8 - 4x) < 6(x - 5) is:

" A number line from negative 5 to 5 in increments of 1.

An open circle is at 3 and a bold line starts at 3 and is pointing to

the right "

Suppose that a poll finds that 31.9​% of taxpayers who filed their tax return electronically​ self-prepared their taxes. If thre
Aneli [31]

Answer: 0.0325

Step-by-step explanation:

Binomial probability distribution formula for x successes in n trials:-

P(X=x)=^nC_x\ p^x\ (1-p)^{n-x}, where n is the number of trials , p is the probability of success.

Given : The probability that taxpayers who filed their tax return are electronically​ self-prepared their taxes : p= 0.319

If three tax returns submitted electronically are randomly​ selected, then the probability that all three were​ self-prepared is given by :-

P(X=3)=^3C_3\ (0.319)^3\ (1-0.319)^{3-3}\\\\=(1) (0.319)^3(1)\\=0.032461759\approx0.0325

Hence, the probability that all three were​ self-prepared =0.0325

Strictly speacking, since 'c' is defined in the statement this shoudl work:

Part 1) According to the exercise, the letter 'c' represents the total cost of the three pounds of oranges. So c is the total cost of the three pounds of oranges.

Part 2) Rami has three pounds of oranges. In order to know how much a pound of oranges cost, he will have to divide by 3 the total cost of the three pounds 'c'

Part 3) The cost per pound is:

cost 1 pound of oranges = c/3
