Answer:

For all real numbers a except 0, we have

a(1/a) = 1

Step-by-step explanation:

Multiplication of real numbers are having the following properties:

i) commutative = ab = ba

ii) associative a(b+c) =ab+ac

iii) Multiplicative identity element exists such that for any number

a*1 =1*a = a

i.e. 1 is identity.

Inverse property is for any a not equal to 0, we have a real number such that

a*that real number = multiplicative identity

i,.e. a(a real number) = 1, a not equal to 0

In other words, there exists an 1/a for all a not equal to 0 satisfying a*1/a = 1

The additional cost per month of a sunroof, spoiler and stereo is represented by three consecutive even integers, respectfully.
lesya [120]

Answer:

16

Step-by-step explanation:

First of all, I think it was "respectively", not "respecfully", =))). A noticeable point.

From the problem, three item's costs are represented by three consecutive even integer.

Thus, we can call cost of spoiler is x, sunroof is x-2, stereo is x + 2. It is conditioned that x is an even number.

Since the sum of the three is 48, we have

(x-2) + x + (x+2) = 48

x+x+x -2 +2 = 48

3x =48

x=16

So the spoiler is 16; thus, the sunroof is 14 and the stereo is 18

Anuta_ua [19.1K]

Answer:

m∠UVW = 53°

Step-by-step explanation:

From the picture attached,

m(∠VTU) = (x - 2)°

m(∠TUV) = (2x + 11)°

m(∠UVW) = (6x - 15)°

Since, ∠UVW is the exterior angle of the ΔTUV,

By the triangle sum theorem,

m∠VTU + m(∠TUV) + m(∠UVW) = 180°

(x - 2)° + (2x + 11)° + (6x - 15)° = 180°

9x - 6 = 180

9x = 186

x = \frac{186}{9}

x = \frac{62}{3}

By the property of exterior angle of a triangle,

m(∠UVW) = m(∠VTU) + m(TUV)

                = (x - 2) + (2x + 11)

                = 3x - 9

Now by substituting the value of x,

(3x - 9)° = 3(\frac{62}{3})-9

           = 62 - 9

           = 53°

Therefore, m∠UVW = 53°
