400 x 80 = 4 x 100 x 8 x 10 = 4 x 8 x 1000 = 32000
1 x 400, 2 x 200, 4 x 100, 5 x 80, 8 x 50, 10 x 40, 16 x 25.
80
80
5 x 80 = 400
5 Times 80 is 400
500 - 5x = 100 500 = 100 + 5x 400 = 5x x = 80 Check it. -400 + 500 = 100 It checks.
400 x 52 = 20,800.
my answer would be 400 + 80 = 480
The Pacific equals 400.
1/5 x 400 = 80 0.75 x 80 = 60 80 - 60 = 20
80 x 5 = 400
