Question

Rewrite 10c-3d = 30 to describe c as a function of d​

Answer 1

C = 3 + 0.3d.

Explanation:

10c - 3d = 30 Add 3d to both sides:

10c = 30 + 3d Divide both sides by 10:

C = 3 + 0.3d.

Answer 2

`c = (3d + 30)/(10)`

Explanation:

`10c - 3d = 30 \\ 10c = 3d + 30 \\ \huge \purple {\boxed{c = (3d + 30)/(10)}} \\`
