Answer:

Step-by-step explanation:

7x+8(x+1/4)=3(6x-9)-8

Opening the brackets

7x + 8x + 2 = 18x - 27 - 8

Collecting like terms

7x - 18x + 8x = -27 - 8 - 2

-3x = -37

Dividing through by -3

x = -37/-3

x = 12 1/3

Jet001 [13]

Answer:

Area 1 is the best option

Step-by-step explanation:

Given Data:

Area 1 = 0.75 dam square

Price = €11,620

Area 2 = 0.009 ha

at €193,500

Area 3 = 0.84a

at €68,900

Where ha ( hectare )

a ( area )

Solution

First we convert all areas to square meter ( m² )

Area 1 = 100 * 0.75 dam square

= 75m²

Cost of area 1/ square meter

= €11,620 / 75m²

= €154.93 / square meter

Area 2 = 0.009 ha * 10,000

= 90m²

Cost of area 2 / square meter

= €193,500 / 90m²

= €2,150 / square meter

Area 3 = 0.84a * 100

= 84m²

= Cost of area 3 / square meter

= €68,900 / 84m²

= €820.23 / square meter

Which is a counterexample for the conditional statement shown? If three distinct points lie in a plane, then the points can form
lina2011 [118]
<h2>Answer:</h2>

We take the example of:

Three collinear points in a plane.

Then we may conclude that they will never form a triangle.

<h2>Step-by-step explanation:</h2>

We know that a conditional statement is given by:

If p then q

where p is the hypothesis of the statement and q is the conclusion of the statement.

Counter example for a conditional statement--

A counter example is an example that makes the general statement is false.

i.e. a example which fulfills the condition of the hypothesis but does not satisfy the conclusion of the given statement.

  • Here the statement is:

If three distinct points lie in a plane, then the points can form a triangle.

i.e. Hypothesis is: Three distinct point lie in a plane.

and conclusion is: The points form a triangle.

So we take a example as:

Three collinear points lie in a plane but they will never form a triangle.
