Answer:
∠ BCA = 45°, ∠ AWD = 90°
Step-by-step explanation:
All angles are right angles by definition.
Diagonals bisect the angles , so
∠ BCA = 45°
Diagonals are perpendicular bisectors of each other, so
∠ AWD = 90°
Answer: A. t - 2d = -240 t - d = 320
Step-by-step explanation:
Let t be the price of a lawn mower at Turf Cutters and d be the price of the same lawn mower at Lawn Masters.
As per given , we have
The price, t, of a lawn mower at Turf Cutters is $240 less than twice the price, d, of the same lawn mower at Lawn Masters.
The difference in price between the mower at Turf Cutters and Lawn Masters is $320.
So, the system of equations can be used to determine the price of the mower at each store is
Hence, the correct option is "A."
Okay, before I start, I apologize for the long answer, but this is going to have a lot of steps and I want to explain each the best I can.
c=5b+a/f
First thing's first, get rid of any constants.
If we treat a as the variable and anything else that's not attached to it as a constant, this is a whole lot easier.
The only thing that isn't attached to a is 5b. Since 5b is positive, we have to subtract that to get it away from a. We end up with:
c-5b=a/f
Now, we treat f as if it is a coefficient. To get a by itself we multiply each side by f. Doing this we get
c-5b*f=a
I belive the only other answer that would work is f*c-5b=a but don't take my word for.
Any Questions?
