The inequality symbol is greater than or equal to. So we just have to find a value to replace r that makes this equation true.
So let’s substitute possible options into the r value.
1. r = 3: 97 ≥ 8 - 144/3. First simplify the fraction to 48/1 because the greatest number that fits into the numerator and denominator is 48. Then rewrite the equation as 97 ≥ 8 - 48 (48/1 is just 48 because 48 divided by 1 is 48.) which equals 97 ≥ 40.
Do the rest as follows:
r=2: 97 ≥ 8 - 144/2 = 97 ≥ 64 ✅
r=3: 97 ≥ 8 - 144/3 = 97 ≥ 40 ✅
r= 5: 97 ≥ 8 - 144/5 = 97 ≥ 104/5 ❌
r= 9: 97 ≥ 8 - 144/9 = 97 ≥ 8 ✅
I apologize if anything is wrong.
