Translate this into symbols:  27 - 1.5x  is equal to or less than 36.  Find x.

Add 1.5x to both sides, so as to make the coefficient of x positive:

27 = 36 + 1.5x, or    -9 = 1.5x,    or x = -6              but also
                                                        x > -6

Check:  let x = -6.   Is the given equation then true? 

27 = 36 + 1.5(-6) => -9 = -9?  Yes.

Check:  let x > -6.  Is  <span>Twenty-seven minus 1.5  of a number (x)  not more than 36?                      27 - 1.5(0) not more than 36?  True.

Thus, x is equal to or greater than -6.</span>

nekit [7.7K]

Answer:

If a triangle has side lengths 3, 4, and 5 units, then its area is 6

Step-by-step explanation:

<em><u>Deductive reasoning </u></em>represents an important form of logical reasoning in which a conclusion is based on the concordance of multiple premises that are generally assumed to be true

we have

If a triangle has side lengths 3, 4, and 5 units, then its area is 6

we know that

1) If triangle has side lengths 3, 4 and 5, then is a right triangle because satisfy the Pythagoras Theorem

2) All right triangles have an area equal to one  half the product of the two smaller side lengths

A=\frac{1}{2}(a)(b)

substitute the values

A=\frac{1}{2}(3)(4)

A=6\ units^2

therefore

The statement is valid based on deductive reasoning
