Final answer:
None of the given ordered pairs are solutions of the equation 6x+3y=15.
Step-by-step explanation:
To find the ordered pair that is a solution of the equation 6x+3y=15, we can substitute the given values for x and y into the equation and check if the equation is satisfied. Let's check each ordered pair:
For (294.5, 61): 6(294.5) + 3(61) = 1767 + 183 = 1950, which is not equal to 15, so it is not a solution.
For (364, 70): 6(364) + 3(70) = 2184 + 210 = 2394, which is not equal to 15, so it is not a solution.
For (605.5, 88.5): 6(605.5) + 3(88.5) = 3633 + 265.5 = 3898.5, which is not equal to 15, so it is not a solution.
Therefore, none of the given ordered pairs are solutions of the equation 6x+3y=15.
