n ← 20
perbandingan brbalik nilai :
50/n = 20/30
20.n = 50.30
20n = 1500
n = 1500/20
n = 75
jadi, tmbahan pekerja = 75-50 = 25 orang
2b + 2p = Rp. 8.400 pensil di kali 2
4b = 9.600
b = 2.400
2(2.400) + 2p = 8.400
4.800 + 2p = 8.400
2p = 3600
p = 1.600
2.) O1 = 22/ 7 x 42 x 42 x 1/4
= 22 x 6 x 42 x 1/4
= 1386
O2 = 22/7 x 21 x 21 x 1/4
= 346,5
O1 - O2 = 1386 - 346,5 = 1039,5
3.) ..-3.. + ..-7.. = -10
..-3.. x ..-7.. = 21
(x-3) (x-7)
