If Lk Mk Lk 7x 10
If LK = MK, LK = 7x10, KN = x + 3, MN = 9x11 and KJ = 28, then what is LJ? 3
Let L, K, M, N and J be points on the number line.
LK = MK
LK = MN + NK
LK = MN KN
7 x 10 = (9 x 11) (x + 3)
7 x 10 = 9 x 11 x 3
7 x 10 = 8 x 14
8x 7x = 10 + 14
x = 4
CL = 7 * 4 10
CL = 18
LJ = LK + KJ
LJ = 18 + 28
LJ = 46
If LK = MK, LK = 7x 10, KN = x + 3, MN = 9x 11 and KJ = 28,
What is LJ?
L.J.
= LK + KJ
= (7 x 10) + 28
= 7x + 18
MN = 9 x 11
Not every measurement is negative because it measures distance without direction.
If the point is limited to one dimension:
MK = MN + KN or | MN KN |
= 10x8 or | 8x14 |
LK = MK
7 x 10 = 10 x 8 or | 8 x 14 |
x = 2/3 or 4
