Question

Evaluate the expression when c =-2.5 and d= 8.9.4d-c

Answer 1

To solve the exercise, replace in the expression the given values of c and d and then operate:

`\begin{gathered} c=-2.5 \\ d=8.9 \\ 4(8.9)-(-2.5)=35.6+2.5=38.1 \end{gathered}`

Therefore, the value of the evaluated expression is 38.1
