In Sean's fish tank, there are 6 times as many goldfish As guppies. There are a total of 21 fish in the tank.how many more golden fish are there than guppies?
Answers
Answer:
The number of gold fishes which are more than guppies are:
15
Step-by-step explanation:
Let the number of guppies in the fish tank =x
and it is given that:
There are 6 times as many goldfish as guppies.
This means that the number of goldfishes in the tank are: 6x
Also, it is given that:
There are a total of 21 fish in the tank.
i.e.
Hence,
- The number of goldfish in the tank = 6×3 = 18 goldfishes.
- and number of guppies in the tank = 3
This means that:
There are 15 (18-3=15) more goldfishes in the tank then guppies.
There are 15 moregoldfish than guppies in Sean's fish tank.
We have,
Let's assume the number of guppies in the tank is 'g'.
According to the given information, the number of goldfish is 6 times the number of guppies, which can be expressed as:
Number of goldfish = 6g
The total number of fish in the tank is given as 21:
Number of goldfish + Number of guppies = 21
Substituting the expression for the number of goldfish, we get:
6g + g = 21
Combining like terms, we have:
7g = 21
To solve for g, we divide both sides of the equation by 7:
g = 21 / 7
g = 3
Therefore, there are 3 guppies in the tank.
To find the number of goldfish, we substitute the value of g back into the expression for the number of goldfish:
Number of goldfish = 6g
Number of goldfish = 6 * 3
Number of goldfish = 18
The difference between the number of goldfish and guppies is:
Number of goldfish - Number of guppies = 18 - 3 = 15
Therefore,
There are 15 moregoldfish than guppies in Sean's fish tank.

(7x+3/4*[x-1])^2
Step-by-step explanation:
The square of the sum of 7 times x. and 3 divided by 4 times the difference of x and 1. This would mean that (7x+3/4*[x-1])^2 You would perform x - 1 in the [] first, which is why they are in the extra brackets. The whole thing is squared, so it is all in parenthesis, being squared. It says 3/4 into x-1. This would mean it's multiplying into x-1.

Answer:
amount invested in mutual fund B; $4,800
amount invested in mutual fund A; $8,200
Step-by-step explanation:
Let the amount invested in mutual fund B be x. Then the amount invested in fund A would be;
(13000-x)
The loss emanating from fund B would be;
3.5% of x
=(3.5/100)*x
=0.035x
The profit resulting from investment in fund A would be;
6% of (13000-x)
= (6/100)*(13000-x)
=0.06(13000-x)
=780-0.06x
The total profit earned from funds A and B in terms of x will be;
780 - 0.06x + (-0.035x)
=780 - 0.095x
The total profit earned was 324, thus;
780 - 0.095x = 324
solving for x;
780 - 324 = 0.095x
456 = 0.095x
x = 4800
Then the amount invested in fund A would be;
13000 - 4800 = 8200
