That system has D. no solutions
Dont mind the sign until fourth step
First step: find divisibles of 90
1,2,3,5,6,9,10,15,18,30,45,90
Second step:find the pairs
1*90,2*45,3*30,5*18,6*15,9*10
Third step: find which one has a difference of 5
None of them is (expand this question more so i can help you)
I think it will be w+15 because if you write 15w that means 15×w and the others don't make sense..
1/10 = .10
2/5 = .40
1/4 = .25
1/3 = .33
Therefore; 3.40>3.33>3.25>3.10
