Solve the formula for converting temperature from degrees celsius to degrees fahrenheit for c? f=9/5c+32

C = (5/9)(F - 32)

Step-by-step explanation:

Please enclose fractional coefficients inside parentheses:   F=(9/5)C+32.  Solve for C as follows:

1) Multiply all three terms of F=(9/5)C+32 by 5, to eliminate the fractional coefficient (9/5):  5F = 9C + 160

2) Subtract 160 from both sides:  

5F - 160 = 9C

3) Divide all three terms by 9, to isolate C:

(5/9)F - (160/9) = C

Simplify:  

C = (5/9)(F - 32)

Example/check:  If F = 32 (freezing), that temperature is 0 C.  Do we get 0 by subbing 32 for F?  YES

If F = 212 (boiling), that temperature in degrees C is 100.  Do we get 100 by subbing 212 for F?  YES

10.8109 amu

Step-by-step explanation:

The average atomic mass of boron is determined as the average of the atomic masses of both isotopes weighed by their respective abundances.

Therefore, the average atomic mass is given by:

The average atomic mass of boron isotopes is 10.8109 amu.
