To solve an equation for a variable, you must isolate the variable on either side of the equation. To do this, simply subtract 32 from both sides of the original equation:
F ( – 32 ) = C + 32 ( – 32 )
F – 32 = C
We have proven that C is equal to (F – 32). This equation (bold) is the answer to your problem.
I hope this helps!
Convert the fraction to a decimal by dividing the numerator by the denominator to approximate the decimal result.
Answer=0.6666666666666
Let t and t+3 be Warren's first and second speeds, respectively. Then:
220/t=231/t+3
220t+660=231t
t=60 mph as his mean speed
