Answer 1

@aloud

Answer 2

replace x by the values 3,4,5,6 in the equation.
you will get the sets

Answer 3

wouldn't it be
5x+4<29
Step 1: Subtract 4 from both sides.
5x+4−4<29−4
5x<25
Step 2: Divide both sides by 5.
5x5<255
x<5
Answer:
x<5

Answer 4

but x<5 isnt one of the answer

Answer 5

@aloud but x<5 isnt one of the answer

Answer 6

but 5 is

Answer 7

5 alone isnt an answer...

Answer 8

there is 2 answers with 5 in it

Answer 9

try for the other numbers as well such 4 and 3

Answer 10

The answer of @aloud 's workout is correct.
The solution lies in a number below 5 and such number is not inclusive. Therefore, the numbers included are 3 and 4. Hence the answer is C.
