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
