temperature have been given in degrees Celsius?
(be sure to label the unknowns and to show equation you use).
Help please I do not understand this.

Tc = (5/9)*(Tf-32)
Tc = (5/9)*(77-32)
Tc = (5/9)*45
Tc = 25 deg. Celsius

Water freezes at 0 C and boils at 100 C. It freezes at 32 F and boils at 212 F. So a change of 100 C degrees is equal to a change of (212-32=) 180 F degrees. So the ratio is 100/180 or 9/5, and the C degree is larger than the F degree so it takes more of the F degrees or fewer of the C degrees to indicate the same difference.
Now you have to adjust the zero point, so degrees F must have 32 subtracted BEFORE multiplying it by 5/9 to get C degrees, or degrees C must FIRST be multiplied by 9/5 and THEN have 32 added to get F degrees.
C=5/9(F-32) or F=32+(C x 9/5)

C = (5/9)(F-32)
Where:
C = temperature in degrees Celsius
F = temperature in degrees Fahrenheit
If you need to show how to derive the formula you would need to plot degrees F vs degrees C and then calculate the formula for the line.
For example, plot this data:
F 212,122, 32 vs C 100, 50, 0
Determine the slope of the line from the plot which will end up being C = (5/9)(F-32)
I can email you an Excel document with the data worked out

Celsius Formula
C = 5/9(F - 32)
C = 5/9(77 - 32)
C = 5/9(45)
C = 225/9
C = 25°
The answer is 77° Fahrenheit equals 25° Celsius

80F, predicted extreme.. one hundred% probability of showers later that's presently 77F with a average breeze, I do say that's a impressive day. I desire i ought to be out fishing as a replace of sitting right here. i'm in Camden, South Carolina.

IF you read your text book you would have found the formula in there for converting C to F.
the link below will explain it for you.

5F*5C -77F +77F/(5/5 F)= 25 C
Easy, ain't?
By the way, there is nothing to understand ... Ask your teacher why they ask you this silly question.
