Question

Найдите 5а -3б если а=8,3 б=4,4

Answer 1

5*8,3-3*4,4

1)5*8,3=5*8 3/10=5*83/10=(5*83)/10=(1*83)/2=83/2

2)3*4,4=3*4 4/10=3*44/10=(3*44)/10=132/10

3)83/2-132/10=415/10-132/10=283/10=28 3/10=28,3

Ответ:28,3

Answer 2

5а-3б=5×8.3-3×4.4=28.3

Answer 3

To find the value of 5а - 3б given the values of а and б, simply substitute the given values into the expression:

а = 8.3 б = 4.4

5а - 3б = 5 * 8.3 - 3 * 4.4

Now, perform the calculations:

5 * 8.3 = 41.5 3 * 4.4 = 13.2

Finally, subtract 13.2 from 41.5:

5а - 3б = 41.5 - 13.2 = 28.3

So, when а = 8.3 and б = 4.4, the value of 5а - 3б is 28.3.
