Question

The formula for degrees Celsius is: C = 5/9 (F - 32), where F stands for degrees Fahrenheit.

Which of the following equations shows the formula correctly solved for F?

1.) F = 5/9 C + 32
2.) F = 9/5 C + 32
3.) F = 5/9 C - 32
4.) F = 9/5 C - 32

Answer 1

You try to manipulate the formula.
We have,
C/5 = (F-32)/9
Therefore,
9C/5 = F-32
Or,
F = 9C/5 + 32

Answer 2

Which mathematical sentence represents the solution for a in the equation 5b = bc + 4a?

1.) a = 5b + bc/4
2.) a = 5b - bc
3.) a = 5b - bc/4
4.) a = 4a/5b - bc

Answer 3

Thanks. :)

Answer 4

@Spacemanifestation Think you could help me with this last one?

Answer 5

You have, 5b = bc + 4a
Keep in mind that we need to solve for a.
Thus, 4a = 5b-bc
Or, a = (5b -bc)/4
