Question

0,4х • 25у, если х = 2,4, у =3

Answer 1

0,4х • 25у= 10 xy

если х = 2,4, у =3 ,

то 10×2,4×3= 24×3=72

Answer 2

0,4х • 25у, если х = 2,4, у =3

0,4 * 2,4 * 25 * 3 = 0,96 * 75 = 72

Answer 3

To calculate the expression 0.4x * 25y, where x = 2.4 and y = 3, you can substitute the given values into the equation and perform the multiplication.

0.4x * 25y = 0.4 * 2.4 * 25 * 3

Let's calculate this expression:

0.4 * 2.4 = 0.96 25 * 3 = 75

Now, we can multiply the results together:

0.96 * 75 = 72

Therefore, when x = 2.4 and y = 3, the value of 0.4x * 25y is 72.
