The variable 'a' represents how much Arthur saves. Because D'John saves $8 per week (7 days), he saves $56. Arthur saves four times more than D'John so $56*4 equals Arthur's total savings for the week; $224.
a=$8(7)*4
a=$56*4
a=$224
When you solve the inequality, you will write down all the x values that satisfy the inequality but they have to be integers. The n is x, it is just a common variable used to help describe what kind of numbers they want.

Answer:
(9/2, 9/2)
Step-by-step explanation:
midpoint formula = (x1 + x2/2, y1 + y2/2)
(7,6) is x1 and y1.
(2,3) is x2 and y2.
Solve:
x-coordinate= (7+2)/2 = 9/2 or 4.5
y-coordinate= (6+3)/2 = 9/2 or 4.5
your final answer is (9/2, 9/2)
decimal form = (4.5, 4.5)
