Question

Which set of solutions will satisfy the inequality −46+r/3 ≤−29

answer options
r = 100 and r = 54

r = 72 and r = 51

r = 51 and r = 26

r = 50 and r = 60

please give an explanation too!

Answer 1

R=51

multiply both sides by 3
r is less than or equal to 51, in the interval (-infinity, 51]
