Because IJ is equal to 15, and IK is equal to 8, all you have to do is to add those two numbers up. IJ and IK are two segments within the segment IK, and they make up the segment IK, so therefore all you need to do is to add IJ and JK.

The answer is D. 23

Hope this answer helped!! Feel free to post more questions if needed!

£440 is divided between David, Mark & Henry so that David gets twice as much as Mark, and Mark gets three times as much as H

Lesechka [4]

Mark received £ 132

Solution:

Given that £440 is divided between David, Mark & Henry

Let "d" be the share of david

Let "m" be the share of mark

Let "h" be the share of henry

Total amount is 440

Therefore,

share of david + share of mark + share of henry = 440

d + m + h = 440 ------- eqn 1

David gets twice as much as Mark

d = 2m ----- eqn 2

Mark gets three times as much as Henry

m = 3h

$h = \frac{m}{3}$ ------ eqn 3

Substitute eqn 2 and eqn 3 in eqn 1

$2m + m + \frac{m}{3} = 440\\\\\frac{6m + 3m + m}{3} = 440\\\\10m = 1320\\\\m = 132$

Thus Mark received £ 132

The sum of twelve and a number is no greater than the sum of twice the number and -8

krok68 [10]

The sum of 12 and a number
(12 + n)

is no greater
< =

then the sum of twice the number and 8
(2n +(-8)) = (2n - 8)

so we have :
(12 + n) < = (2n - 8)
