Given:
2 pythons : 6 ft each
3 corn snakes : same length
Total length = 21 ft.
Let x be the length of one corn snake.
2(6ft) + 3x = 21 ft
12ft + 3x = 21 ft
3x = 21 ft - 12 ft
3x = 9 ft
x = 9ft/3
x = 3ft
Each corn snake is 3 ft long.
3x + 12ft = 21ft
You would change 12% into a decimal, which is .12 then multiply it by 48. The answer is 5.76
The final number is 100% of, or the same as the original number
Ex: original number = 1
1(.25) = .25 1 + .25 = 1.25
1.25(.20) = .25 1.25 - .25 = 1
