Answer:
(6, 0)
Step-by-step explanation:
There are a few different methods to solve system of equations. For this problem, you can use substitution by solving one of the equations for a variable and then substituting this expression into the other equation to solve for the remaining variable:
x - y = 6, add 'y' to both sides to solve for 'x': x - y + y = 6 + y or x = 6 + y
Using the expression '6 + y' for the value of 'x' in the second equation:
2x + 3y = 12 or 2(6+y) + 3y = 12 or 12 + 2y + 3y = 12 or 12 + 5y = 12
Subtract 12 from both sides: 12 + 5y - 12 = 12 - 12 or 5y = 0 so y = 0
Now that you know the value of 'y', you can solve for 'x':
x = 6 + 0 or x = 6
Put the values of 'x' and 'y' into an ordered pair: (6,0).

Answer: 243.6
Step-by-step explanation:
For us to solve the question and round off 243.583 to the nearest tenth. First, we need to look at the number beside the tenth number which is 8.
Since 8 is more than 4, we simply add 1 to the tenth number which implies that we add 1 to the number in tenth place which is 5. Adding one means the number change to 6. Therefore, rounding 243.583 to the nearest tenth will be 243.6.
test 1 = 50
test 2 = 70
70+50 = 120
so tests are .5*120/2 = 30 points
hw = .25*100= 25 points
quiz = .25*75 = 18.75
total score = 30+25+18.75 = 73.75
