Question

Если x= 2,13 , y= 7,87 , то 0,74x + 0,74y + 2,6 =

Answer 1

Ответ:

10

Пошаговое объяснение:

0,74x + 0,74y + 2,6 = 0,74*(x +y) + 2,6 =0,74*10+2.6=7,4+2,6=10

Answer 2

To find the value of the expression 0.74x + 0.74y + 2.6 when x = 2.13 and y = 7.87, simply substitute the values into the expression and perform the calculations:

0.74 * 2.13 + 0.74 * 7.87 + 2.6

Multiply first:

1.5742 + 5.8166 + 2.6

Now, add:

1.5742 + 5.8166 = 7.3908

Now, add 7.3908 and 2.6:

7.3908 + 2.6 = 9.9908

So, when x = 2.13 and y = 7.87, the value of 0.74x + 0.74y + 2.6 is approximately 9.9908.
