Answer:
- C = (5/9)(F -32)
- 50°F ⇒ 10°C
Step-by-step explanation:
Starting with the formula for degrees Fahrenheit, we can solve for degrees Celsius.
F = 32 +9/5C
F -32 = (9/5)C . . . . . subtract 32
(5/9)(F -32) = C . . . . multiply by the inverse of the coefficient of C
The formula for Celsius temperature from Fahrenheit temperature is ...
C = (5/9)(F -32)
__
For F = 50, the corresponding Celsius temperature is ...
C = (5/9)(50 -32) = (5/9)(18) = 10 . . . degrees Celsius
Before you use the quadratic formula, you have to make sure the equation itself is a quadratic and that a and b are not 0.
Just solve the equation! if the dot means multiply, then
35 - (5 x 2) + (16 / 4) because of BIDMAS or PEDMAS or whatever abbreviation you use, where the order is Brackets Indices Division Multiplication Addition and Subtraction.
35 - 10 + 4 = 29
Therefore the answer is 29.
Hope I helped!
