Answer:
6
Step-by-step explanation:
=> -x+4
<u><em>Given that x = -2</em></u>
=> -(-2)+4
=> 2+4
=> 6
First step you would have to do would be to times 35 by 12 to see how much you would have to pay for 12 months.
35 x 12 = 420
Then, as you said, you a down payment of 600 so then you'd add.
600 + 420 = 1,020.
So the total cost of the computer would be $1,020.
Answer:
10
Step-by-step explanation:
2+2=4
4+6= 10
Find Angle B: B = 180 - (82+55) = 43. Then apply the law of sines:
b 8 cm
--------- = ----------
sin 43 sin 55
(sin 43)(8 cm)
Solving for b, we get b = ------------------- = 6.66, or 6.7 (cm, to the nearest tenth).
sin 55
Answer:
a) 
b) 
Step-by-step explanation:
Data
Brine a (Ba)
Brine b (Bb)
we have that per every minute the amount of solution that enters the tank is the same as the one that leaves the tank (15 Lt / min)
, then the amount of salt (y) left in the tank after (t) minutes: 
Finally:
a)
b) 
being y(t) the amount of salt (y) per unit of time (t)
