Write an expression that can be used in over a temperature from degrees Celsius see to degrees Fahrenheit and then use the expression took over 25°C degrees Fahrenheit

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.

they can both be solutions depends on the equation

step-by-step explanation:

what is the equation? ?

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
