Write the word sentence as an inequality.
1.) A number n is greater than 1
2.) Twice the number p is fewer than 7
3.) A number w minus 3 is less than or equal to 10
4.) A number z is divided by 2 is at least -6
Remember: A solution set is more than one answer, it is all the answers
that work in the inequality. SUBSTITUTE the answer to see if it works
(plug-n-chug the answer)
