One species of fish in a fishery had an initial population of 255 fish and grew by 25 fish each season. A second species that was being overfished started with an initial population of 450 fish, and then decreased by 40 fish each season. Assuming a linear change, write equations for the populations of each species. When will the two populations have the same amount of fish? After how many seasons will the second species be eliminated?
Answer:
they intersect at 3.5 seasons, 312 fish. the second gets elimed at 11 seasons
Step-by-step explanation:
equations:
first:
amount of fish = 225 + 25*season
second:
amount of fish = 450 - 40*season

The number of messages posted each day on an online message board during the first 5 days it was open are listed below
2,350 2,900 3,450 4,000 4,550
The number of messages posted each day follows a pattern. Which expression can be used to determine the number of messages
posted on the nth day?
O A. 2,350n
ов.
550(n + 1,800)
O C.
550n + 1,800
O D.
1,800n + 550
= C, 550n + 1800
Here is how you make a expression for a sequence:
1) Firstly, identify the number gap. This is 550. 2350 + 550 = 2900. 2900 + 550 = 3450, ect. So this means that it is 550n.
2) n is basically just the number in the sequence it stands on. n for 2350 is 1. So now you need to know what you must add to 550n to get whatever n is. We will choose 2350. n is 1 for it. 550 x 1 = 550. 2350 - 550 = 1800. So it is 550n + 1800.

Bill worked 24 hours last week and earns $8.25 per hour. Use front-end estimation to find
an estimate of the total amount of money he earned.
A) $160 B) $180 C)$200
D) $270
Answer:
198 dollars
Step-by-step explanation: First you make the 24 into a decimal, you can put 2 0s to make it 24.00. Then you line up the 8.25 and the 24.00 like this 24.00
x 8.25 then multiply away! don't bother with decimals for now. once you finish multiplying count how many numbers are behind the decimal and move the decimal that many times.

A bag contains 7 green marbles,2 white marble s, 5 orange marbles,9 blue marbles, and 7 red marbles. a marble will be drawn from the bag and replaced 180 times what is a reasonable prediction for the number of times a white or red marble will be drawn?
The reasonable probability that a white or red marble will be drawn all 180 times is; (3/10)¹⁸⁰.
Probability with replacementSince the probability is with replacement;
First, the total number of marbles in the bag is; 7+2+9+5+7 = 30.Hence, the probability that a white or red ball is drawn each time is; 2+7 = 9 possible outcomes.
Hence, it follows that the probability for white or red each time is; 9/30 = 3/10
Hence, when drawn 180 times, the probability is;
P = (3/10)¹⁸⁰.Read more on probability;

2) 2015 difference
(6-4)100
2(100) = 200 coin difference
3) Henry is red. just look at the points where red is ABOVE blue

Arun bought a pair of skates at the sale where the discount given was 20%. If the amount he pays is 1600 find the marked price
Answer:
2000
Step-by-step explanation:
1600 is 100% - 20% = 80% of the original price.
So it is 4/5 of the original price.
So, the marked price is 1600 * 5/4 = 2000

simultaneous equations find x and y
2x/ y + y/ x =3
3x-y=2
Answer:
x = 1 and y = 1
Step-by-step explanation:
2x/y + y/x = 3
3x - y = 2
we first of all get the simple equation from the two equations and in this case we will use substitution method
3x - y = 2
then we make y the subject of the formula
y = 3x - 2
let's use y on the top equation to substitute
2x/y + y/x = 3
2x/3x - 2 + 3x - 2/x
like terms cancel
thus:
2x/1 + 1/x = 3
3x -2x = 1
x = 1
ANDAND since we have x, we still use substitution method to find y
3x - 2 = y
3 (1) - 2 = y
3 - 2 = y
y = 1
Solve (-7/3)x -3=-53
Answer: 21
Step-by-step explanation:
Add 3 to both sides so then it would be -7/3x=-49
Then multiply the reciprocal of -7/3 which is -3/7 to both sides
It would then be x=-49 times -3/7 and if you simplify that it becomes 21
