Question

Which expression is equivalent to c – 0.51 + 0.3c?

Answer 1

In order to find or answer we need to combine terms that have "c" in them.

Now, the terms with c are 0.3c and c; therefore, we can say

`c-0.51+0.3c=(c+0.3c)-0.51`
`\rightarrow1.3c-0.51`

Therefore,

`c-0.51+0.3c=1.3c-0.51`

Hence, the top left choice is the correct one.
