Question

Can someone please help me??????

Answer 1

1. Subtract 11 from both sides to isolate the variable r.
2. Divide by -6 on both sides, but remember whenever you divide or multiply by a negative number, you'll have to flip the inequality sign.
3. Find an answer that works with whatever inequality you get!

Answer 2

well just plug in the R's you are given and you should be able to figure it out you can eliminate any R's with a negative number because when you have a negative sign behind a minus sign it's positive so the first and last are eliminated now just use simple maths r = 7
11-42<-48
-31<-48

which isnt true -31 is bigger than -48 not less then so the only one left is r = 11
11-66<-48
-55<-47 which is true so your answer is
r = 11
