Answer:

The number of gold fishes which are more than guppies are:

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.

$x+6x=21\n\ni.e.\n\n7x=21\n\nx=(21)/(7)\n\nx=3$

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.

a box of 10 markers weighs 105 grams. if the empty box weights 15 grams, how much does each marker weigh?

Answers

first, ,how much do all the markers weight? the box with the markers weights 105, so without the box all the markers weigh 105-15=90 grams.

so 90 grams is the weight of 10 markers together, and each of them will weigh one tenth of this: 90/10=9

so each marker weights 9 grams.

Final answer:

The weight of each marker can be found by first subtracting the weight of the empty box from the total weight to get the weight of all markers, then dividing by the number of markers. Each marker weighs 9 grams.

Explanation:

Firstly, we can find the total weight of the markers by subtracting the weight of the empty box from the total weight of the box with the markers. Doing this calculation (105 grams - 15 grams) gives us the total weight of the markers, which is 90 grams. As there are 10 markers, we can find the weight of each marker by dividing the total weight of the markers by the number of markers. This calculation (90 grams / 10) results in each marker weighing 9 grams.
