Question

1,4m-0,3n, если m=2.6; n=5.09

Answer 1

1,4*2,6-0,3*5,09=3,64-1,527=2,113

Answer 2

1.4m-0.3n
при m=2,6, n=5,09
1,4*2,6-0,3*5,09=3,64-1,527=2,113

Answer 3

To calculate the expression 1.4m - 0.3n, where m = 2.6 and n = 5.09, we substitute the given values into the expression:

1.4m - 0.3n = 1.4(2.6) - 0.3(5.09)

Now, we can simplify the expression by performing the arithmetic calculations:

1.4(2.6) = 3.64 0.3(5.09) = 1.527

Therefore, 1.4m - 0.3n = 3.64 - 1.527 = 2.113.

So, when m = 2.6 and n = 5.09, the value of 1.4m - 0.3n is approximately 2.113.
