Question

What simplified algebraic expression might you use to describe the sum of a number k and the number 10 less than the triple of k?

Answer 1

(k + (3k - 10) ???
The sum means add.....triple k means 3k.....you better get a second opinion

Answer 2

looks good to me
combine like terms to finish

Answer 3

" the sum of " means add
" triple k " means 3k -- (3 times k)
" less then " means subtract

k + 3k - 10 -- combine like terms
4k - 10
