Answer:
x = the wight of the large box
y = the weight of the small box
A delivery of 3 large boxes and 2 small boxes has a total weight of 73 kilograms.
3x + 2y = 73
A delivery of 8 large boxes and 4 small boxes has a total weight of 177 kilograms.
8x + 4y = 177
by solving the system of equations
3x + 2y = 73
8x + 4y = 177
we find
x = 15.5 kg
y = 13.25 kg
the large box weights 15.5 kg.
the small box weights 13.25 kg.
The answer to which is bigger is -5 because it is closer to zero
Answer:
DI = 38
Step-by-step explanation:
Δ EHC and Δ DIC are similar and ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
2DI = 76 ( divide both sides by 2 )
DI = 38
Answer: 441

Step-by-step explanation:
Total distance covered=distance covered by walking+distance covered by jogging
=6/7+4/5=30+28/35

=6/7-4/5
=30-28/35
=2/35miles
