If you are working with time or days, you can't put in a negative value because if you are doing an experiment, you can't go back in time to do that experiment to gather data. (Time for the most part considered to be an input value so that's why I used it as an example.)
Answer:
y= (C - Az)/B
Step-by-step explanation:
Az +By = C
Az - Az + By = C - Az
By = C - Az
Divide both side by the coefficient of y which is B
therefore we have:
y = (C - Az)/B
Answer:
x - y = 25
Step-by-step explanation:
3x - 4y = 15
-2x + 3y = 10
Add the two equations together
3x - 4y = 15
-2x + 3y = 10
----------------------
x - y = 25
ANSWER
Find out the how much does it grow in 8 weeks
To proof
As given
A coral reef grows 0.17 m every week.
now for the 8 weeks
coral reef grows in the 8 weeks = 8× 0.17
= 1.36 m
As
1 meter = 1000 millimeter
To convert growth of coral reef in the millimeter
= 1.36 × 1000
= 1360 millimeter
Hence 1360 millimeter be the coral reef grows in 8 weeks
