Question

Which number(s) below belong to the solution set of the inequality Check all that apply. x + 30 < 60 a.50 b.45 c.300 d.1 e.29 f.30

Answer 1

e.29 d.1

Explanation:

• x+30<60 :

we will replace with the values we have :

• 300 that's a big number . Obviously it isn't a solution
• 50 : 30+50 = 80>60 so no
• 45: 30+45= 75 >60 so no
• 30+30 = 60 we have < not ≤ so no
• 1 yes . it's obvious
• 29 +30 = 59<60 so yes !
