Answer:
David receives £90
Step-by-step explanation:
Let David's share be D
Let Mark's share be M
Let Henry's share be H
From the question, we obtained the following data:
David gets twice as much as Mark i.e
D = 2M
M = D/2
Mark gets three times as much as Henry i.e
M = 3H
H = M/3
H = (D/2) /3
H = D/6
The sum of their shares is £150 i.e
D + M + H = 150
D + D/2 + D/6 = 150
Multiply through by 6 to clear the fraction
6D + 3D + D = 900
10D = 900
Divide both side by the coefficient of D i.e 10
D = 900/10
D = 90
Therefore, David receives £90
(a) it is always true -5.2 x ( -1.4 ) =7.28 AND -1.4 x (-3.6) =5.04
(b)the rule for multiplying negatives is negative x negative = positive.

Final answer: 7.8
Same thing. 22^2+b^2=33^2
484+b^2=1089
b^2=605
b=24.60
