Answer:
the ordered triple of these equations will be:
(x, y, z) = (6, 1, 5)
Step-by-step explanation:
Given the equations



As

We can get the value of x by adding the first and third equation
so


so the equations become



Putting x = 6 and y=1 in the first equation 



Therefore, the ordered triple of these equations will be:
(x, y, z) = (6, 1, 5)

50 miles per hour divided by 30 minutes which is 1/2 hours thus 50/2=25 miles.
1,000,000 x (15/100)
1,000,000 x (0.15)
150, 000
He can spend 4 dollars on each sandwich cause 27-3(the kids meal) =24 24 divided by 6=4. 4 being the amount per sandwich!
