X = 250 mg tabs
y = 500 mg tabs
2200x + 1800y = 39200....multiply by -1
2200x + 2200y = 44000
--------------------------------
-2200x - 1800y = - 39200 (result of multiplying by -1)
2200x + 2200y = 44000
--------------------------------add
400y = 4800
y = 4800/400
y = 12...... the 500 mg tabs (y) costs $ 12 per bottle
2200x + 2200y = 44000
2200x + 2200(12) = 44000
2200x + 26400 = 44000
2200x = 44000 - 26400
2200x = 17600
x = 17600/2200
x = 8 <== the 250 mg tabs (x) costs $ 8 per bottle
Answer:
long
Step-by-step explanation:
well, as you can clearly see this is certainly not a short rectangle. maybe a little stocky, but certainly not short. also, I'm not very good at math, so dont ask me.
The statements that aer true or not or whatever
hmm, let's try te sencnarios
remember the commutative property of multiplication
ab=ba
so
what if they are both negative?
well, the negatives would cancel to leave with positive
the oposite would be both positive resulting in a positive
if they are differnt signs then result is negative
oposite would be still different signs so still negative
true statment
I believe it would be D) ST ≈ TR
