Question

Алгебра 5x+7y при x=3/5, y=4/7​

Answer 1

Ответ:

7

Объяснение:

5*3/5=3

7*4/7=4

3+4=7

Answer 2

To evaluate the expression 5x + 7y when x = 3/5 and y = 4/7, we substitute these values into the expression:

5x + 7y = 5(3/5) + 7(4/7)

Now, let's simplify the expression:

5(3/5) = 3 7(4/7) = 4

Therefore,

5x + 7y = 3 + 4 = 7

So, when x = 3/5 and y = 4/7, the value of 5x + 7y is 7.
