Answer:
The solution is (0, 4)
Step-by-step explanation:
Please pay attention to the first two equations and drop the last two:
12x−5y=−20 y=x+4 x=x=x, equals y=y=y should ideally be:
12x−5y=−20
y=x+4
Let's find x. Substitute x + 4 for y in the first equation, obtaining:
12x - 5(x + 4) = -20
Carrying out the indicated multiplication, we get:
12x - 5x - 20 = -20, or 7x = 0
If x = 0 then y must be 0 + 4, or 4.
The solution is (0, 4)
Each camera costs $651 dollars, assuming I understood the question format correctly.
Find 60% of 465, which is 186. Because it is markup, add 186 to the original price. 465+186 = 651.
Therefore, the price is $651.

Answer:
number of bottles per minute equals 6.667 bottles ( approximately 7 bottles)
6 hours= 2400 bottles
7 hours = 2800 bottles
8 hours = 3200 bottles
Step-by-step explanation:
600 bottles = 1 .5 hrs ( 90 minutes)
bottles per minute;
600= 90mins
? = 1 min
( Cross multiply)
1 min is equal to 6.667 bottles ~7 bottles
* The same procedure is used for the rest
note;
6 hours is equal to 360 minutes
7 hours is equal to 420 minutes
8 hours is equal to 480 minutes
