Answer:
25°C = 77 degree Fahrenheit.
Step-by-step explanation:
In this question we have to write the expression showing the relation between degree Celsius and degree Fahrenheit first.
where C = degree centigrade and F = degree Fahrenheit
Although the question is not clear in the next part but assuming that we have to use this expression to convert 25°C to degree Fahrenheit,
We will plug in the value of C in the expression,


F = 45 + 32
F = 77
Therefore, 25°C = 77 degree Fahrenheit will be the answer.
That is because The curiculem changes with time.
Step-by-step explanation:
43=0.34x+19.5
=> 0.34x+19.5 = 43
=> 0.34x = 43 - 19.5
= 23.5

=> x = <u>69.117</u><u> </u><u>(</u><u>Ans</u><u>)</u>
