Question

Evaluate the expression with the given values._ 5c + 20 6b if a=2.b=5, and c=6 a +8

Answer 1

to evaluate the expression substitute the values of a,b and c given

`6b-(5c+20)/(a+8)`

a=2 b=5 and c=6

`\begin{gathered} (6\cdot5)-((5\cdot6)+20)/(2+8) \\ 30-(30+20)/(10) \\ 30-(50)/(10) \\ 30-5 \\ 25 \end{gathered}`
