Question

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

Answer 1

Answer:

$c = \frac{3d + 30}{10}$

Step-by-step explanation:

$10c - 3d = 30 \\ 10c = 3d + 30 \\ \huge \purple {\boxed{c = \frac{3d + 30}{10}}}$

Answer 2

Answer:

C = 3 + 0.3d.

Step-by-step explanation:

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

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

C = 3 + 0.3d.
