The Celsius to Fahrenheit formula: F = 9/5 C + 32
Solve this formula for C. Check all answers that are true.
First step is to multiply by 9 on each side.
First step is to add 32 to both sides.
The next step from F - 32 = 9/5 C, could be to multiply both sides by 5
The next step from F - 32 = 9/5 C, could be to divide both sides by 5
Solution: 5/9F - 32 = C
To solve this equation for C, you would have to distribute at some point.
The correct step from F - 32 = 9/5 C to solve for C is to multiply both sides by 5, not divide.
So, the correct solution is:
5(F - 32) = 9C
Simplifying further, we get:
5F - 160 = 9C
Dividing both sides by 9, we have:
C = (5F - 160)/9
The correct steps to solve the equation F = 9/5 C + 32 for C are:
1. Start with the equation: F = 9/5 C + 32.
2. Subtract 32 from both sides: F - 32 = 9/5 C.
3. To isolate C, multiply both sides by 5/9: (5/9)(F - 32) = C.
So, the correct solution is C = (5/9)(F - 32).
