The given coordinates when plotted and joined together on the Cartesian plane appears to form a scalene triangle.
19/307/10 - 1/15 := (7/10 * 3/3 )- (1/15 * 2/2)= 21/30 - 2/30= 19/30
(-2. -10) (3, -15) (-2, -19) (9, -21)
2/3 + 3/5 =10/15 + 9/15= 19/15(19/15) / 2 = 19/3019/30
Yes. 15*(2/3) = 10 and 21*(2/3) = 14
7/10 of 15 = 15*7/10 = 21/2
19
It is probably impossible to enumerate all the methods. Apart from long multiplication you can have Two-way partitioning: (10 + 9) * (20 + 1) = 200 + 10 + 180 + 9 = 399 This is usually done in a 2x2 grid. Partitioning 21 19*(20 + 1) = 19*2*10 + 19*1 = 38*10 + 19 = 380 + 19 = 399 Partitioning 19 (20 - 1)*21 = 2*10*21 - 1*21 = 42*10 - 21 = 420 - 21 = 399 Or. if you are savvy enough, Difference of two squares (20 - 1)*(20 + 1) = 202 - 11 = 400 - 1 = 399
1 + 18 = 19, 2 + 17 = 19, etc. 10 + 9 = 21 correct
Yes...There will be a Naruto: Ultimate Ninja Storm 2 but it will be based on Shippuden and it will be released on 10/15/10 in Europe, 10/19/10 in America and on 10/21/10 in Japan on the Xbox 360 and PS3
15/14 * 21/10 = 3/14 * 21/2 = 3/2 * 3/2 = 9/4
19/21 - 2/7 = 19/21 - 6/21 = 13/21
The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors 1+3+5+10=19, 1+2+6+10=19, 1+3+15=19, and 3+6+10= 19.
