Final answer:
The value of 5x+9y when x = 3/5 and y = 7/9 is 10.
Step-by-step explanation:
To find the value of 5x+9y, we need to substitute the given values of x and y into the expression. Let x = 3/5 and y = 7/9.
Substituting these values into 5x+9y:
5(3/5) + 9(7/9) = 3 + 7 = 10
Therefore, the value of 5x+9y when x = 3/5 and y = 7/9 is 10.
