Answer:

Any value except -3.44 will make the equation equal to 28.1

Step-by-step explanation:

We are told to multiply the quotient of the fraction by 28.1 to make 28.1. So, it is obvious that the fraction has to simplified to a one. This is possible with any number as whatever the value of x, the numerator and denominator will be equal. But, in the case of -3.44, it will make 5e fraction 0/0, which is undefined and never equal to 1.

I hope this helps

Answer:

Option (G)

Step-by-step explanation:

Volume of the real cane = 96 in³

Volume of the model of a can = 12 in³

Volume scale factor = \frac{\text{Volume of the model}}{\text{Volume of the real can}}

                                 = \frac{12}{96}

                                 =\frac{1}{8}

Scale factor of the model = \sqrt[3]{\text{Volume scale factor}}

                                          =\sqrt[3]{\frac{1}{8}}

                                          =\frac{1}{2}

Therefore, scale factor of the model of a can = \frac{1}{2} ≈ 1 : 2

Option (G) will be the correct option.

The graph below shows a proportional relationship between yyy and xxx.
Elena-2011 [213]

Answer:

k = 40

Step-by-step explanation:

Given

The attached graph

Required

Calculate the constant of proportionality.

Represent the required constant with k.

Such that:

k = \dfrac{y}{x}

Pick any two corresponding values of x and y

(x,y) = (1,40)

This means that:

x = 1\ and\ y = 40

k = \dfrac{y}{x} becomes

k = \frac{40}{1}

k = 40

Answer:

x = 4

31x + 6 = 130

12x + 2 = 50

Step-by-step explanation:

two angles side by side are equal to 180.

(31x + 6) + (12x + 2) = 180

43x + 8 = 180

43x = 172

x = 4

31x + 6 = 124 + 4 = 130

12x + 2 = 48 + 2 = 50
