Answer: B
Step-by-step explanation:
Running at the same constant rate, 6 identical machines can produce a total of 270 bottles per minute. Since the machines are identical and running at the same constant rate, it means each of them as the same rate. The rate of each machine can produce would be determined by dividing the combined unit rate by 6. It becomes
270/6 = 45 bottles per minutes
The rate for 10 machines running at the same constant rate would be
10 × 45 = 450 bottles per minutes.
If the 10 machines produce 450 bottles per minutes, then,
In 4 minutes, the 10 machines will produce 4 × 450 = 1800 bottles
There are two equations you will need in order to solve this question:
When you substitute 4y for x in the top equation, that should give you 20
It is 15 / 1000 in the fraction form.
Step-by-step explanation:
the answer would be -9.
28x -63 = -315
add 63 to -63 and -315
there u get this
28x= -252
then divide 28 both sides
x=-9
