The answer to the equation is 4x-5. This is called expanding brackets. So you have to do 2x times by 2 then u do 3x2 so whatever is on the inside u multiply it by the outside. If the answer is negative I must put a minus instead of plus
Answer:
$7.43
Step-by-step explanation:
First, solve for what each of the 5 friends are paying:
130/5 = 26
Then, solve for what each person is paying with the addition of 2 people:
130/7 = 18.57
Last, subtract to find the answer:
26-18.57 = 7.43
Answer:
Step-by-step explanation:
Given that initial population is 3100
The population is decreasing continuously which means the population at any time t can be represented by the funciton
where t = time and r = rate
The population is continuously decreasing at the rate of r% per unit of time.
When t becomes very large,
we get limit would be P0 (0) =0
The population will decrease and almost tend to 0 as time advances.
There is no chance for further decrease as population cannot be negative
So limiting population is 0.
The surface of the ocean is 0 meters.
Because the fish is below the surface it would be a negative number. ( it is less than 0)
The elevation of the fish would be -12 meters.
