Answer:
A) The sum of given digits is 5417.412
B ) The sum of given digits is 401.103
Step-by-step explanation:
Given sum of numbers as :
A ) 5 × 10³ + 4 × 10² + 1 ×
+ 7 ×
+ 4 ×
+ 1 ×
+ 2 ×
Or , 5000 + 400 + 10 + 7 × 1 + 0.4 + 0.01 + 0.002
or, ( 5400 + 10 + 7 ) + ( 0.4 + 0.01 + 0.002 )
Or, 5417 + 0.412
Or, 5417.412
Hence The sum of given digits is 5417.412
B ) 4 × 10² + 1 × ( 1
) + 3 ×
Or, 400 + 1 × (
) + 0.003
Or, 400 +
+ 0.003
Or, 400 + 1.1 + 0.003
Or, 401.103
Hence The sum of given digits is 401.103
Answer
It is -17.6, gl with your work btw!
We know that
<span>[average speed]=distance/time
distance=59+70-----> 129 km
time=4+5----> 9 hours
</span>
[average speed]=129/9----------> 14.33 km/hour
If we multiply the first equation by 2 we get
2x - 4y = 12
but the second equation is
2x - 4y = 10
2x - 4y can't have 2 different values so the are no solutions
