Un = 4n - 68
60/88 = 30/44 = 15/22
60-39=21.
65% 39/60, *100
7h+39=60 Take away 39 from both sides (called isolating your variable) 7h=21 Divide by seven, because (I assume) you are looking for h, not 7h h=3 And to check: 7(3)+39=60 21+39=60 60=60
Un = 4n - 68
55 + 5N or 60 + 5(N - 1)

2n(n+1)
2n(n+1)
60/88 = 30/44 = 15/22

go ask your teacher and tell him hes dumb
39 out of 60 = 39 / 60 = 0.65Converting decimal to a percentage: 0.65 * 100 = 65%
60-39=21.
39 out of 60 = 39 / 60 = 0.65Converting decimal to a percentage: 0.65 * 100 = 65%
39 x 60 = 2,340
