Answer 3

To evaluate the expression $\frac{2}{7} c - 0.2d$ when $c = -28$ and $d = 15$, you can substitute the values of $c$ and $d$ into the expression and then perform the calculations:

Given: $c = -28$ $d = 15$

Expression: $\frac{2}{7} c - 0.2d$

Substitute the values: $\frac{2}{7} (-28) - 0.2(15)$

Now perform the calculations: $\frac{-56}{7} - 3$

Simplify: $-8 - 3$

Final result: $-11$

Therefore, when $c = -28$ and $d = 15$, the value of the expression $\frac{2}{7} c - 0.2d$ is $-11$.
