Onto ya ga Maggie ga e bereke sentle. Fa a e beela mo go 450, totatota e nna 468. Fa e le gore pharologanyo e lekana mo diresepeng tsotlhe, o tshwanetse go e beela mo go bokae fa resepe ya gagwe e tlhoka 520 degrees?

Diane gave a number train a starting value of 20. This starting value plus half the number was divided by 5 and the resulting value was multiplied by the starting value minus 12. What was the final value of the number train?
Onto e off ka di degree di le 18 ka gonne 468 - 450 = <<468-450=18>>18
Onto e off ka 4% ka gonne 18 / 450 x 100 = <<18/450*100=4>>4%
Ka jalo X + .04X = 520
Ka jalo 1.04X = 520
Thempheretšha e e tshwanetseng go e bewa ke 500 ka gonne 520 / 1.04 = <<520/1.04=500>>500
#### 500 

If Diane gave a number train a starting value of 20, half the number is 1/2*20=<<20-10=10>>10
The starting value plus half the number is 20+10=<<20+10=30>>30
This starting value plus half the number was divided by 5, giving a total of 30/5 = <<30/5=6>>6
The starting value minus 12 is 20-12=<<20-12=8>>8
The resulting value after dividing by 5 was times by the starting value minus 12, a total of 8*6 = <<8*6=48>>48
#### 48
