The equation to convert from degrees Celsius to degrees Fahrenheit is F=1.8C+32, whereas a simpler estimate for this conversion

is F=2C+30. By solving each of these equations for C, we can convert from degrees Fahrenheit to degrees Celsius.

Answer:

The answer to your question is  Equation 1  C = (F -32)/1.8

                                                      Equation 2   C = (F - 30)/2

Step-by-step explanation:

Data

Equation 1   F = 1.8C + 32

Equation 2  F = 2C + 30

Solve both equations for C

Equation 1

- Substract 32 in both sides

                  F - 32 = 1.8C + 32 - 32

- Simplify

                  F - 32 = 1.8C

- Divide both sides by 1.8

                  C = (F -32)/1.8

Equation 2

                   F = 2C + 30

- Substract 30 in both sides

                  F - 30 = 2C + 30 - 30

- Simplify

                  F - 30 = 2C

- Divide both sides by 2

                  C = (F - 30)/2

Please help!! Which of the following is equal to the rational expression when x ≠ 2 or -4? 5(x-2)/(x-2)(x+4)
Stels [109]

Answer:

5 / (x+4)      x ≠2 x≠-4

Step-by-step explanation:

5(x-2)/(x-2)(x+4)

The denominator cannot be zero so x ≠2 x≠-4

Cancel like terms in the numerator and denominator

5 / (x+4)      x ≠2 x≠-4

bagirrra123 [75]

Answer:

B) 1153000

Step-by-step explanation:

Given

See attachment

Required

Number of households without computer in 2009

From the attachment, we have:

n=5170000 --- survey

p = 22.3\% --- proportion without computer

So, the actual number is:

Number = p * n

Number = 22.3\% * 5170000

Number = 1152910

Number \approx 1153000

<em>Hence: (B) is correct</em>
