E=number of eight cent stamps
t=number of ten cent stamps bought
w=number of 2 cent stamps bought

number of eight=number of ten
e=t

as many 2 cent as the other 2 combined
e+t=w or
2e=w=2t

total she bouthgt 4.40
4.40=440 cents
8e+10t+2w=440
solve for t or e, I solve for t
8t+10t+2(2t)=440
18t+4t=440
22t=440
divide 22
t=20


t=e
20=e
w=2e

A, E and B lie on a straight line segment.
Jobisdone [24]

The length of line BE on the given line segment is 3.5 m.

The given parameters:

  • <em>Length BD = 3 m</em>
  • <em>Length CD = 15 m</em>
  • <em>Length AB = 21 m</em>

<em />

The sketch of the given line segments is presented in the diagram uploaded.

The length of BE is determined by applying similar triangle theorem as follows;

\frac{CB}{AB} = \frac{BD}{EB} \\\\\frac{15 + 3}{21} = \frac{3}{EB} \\\\18EB = 63 \\\\EB = \frac{63}{18} \\\\EB = 3.5 \ m

Thus, the length of line BE on the given line segment is 3.5 m.
