A shark weighs 405 kg and 68 grams a second shark weighs 324 kg and 75 g how much more does the first shark weigh in grams than

mariarad [96]

For this case we have to by definition:

1 kg equals 1000 grams

Shark 1:

405 kg and 68 grams

$405 kg * \frac {1000 g} {1kg} = 405,000 grams$

Thus, shark 1 weighs 405,068 grams.

Shark 2:

324 kg and 75 grams

$324 kg * \frac {1000 g} {1 kg} = 324,000 grams$

Thus, shark 2 weighs 324,075 grams.

Subtracting we have:

$405.068 grams-324.075 grams = 80.993 grams$

Thus, shark 1 weighs 80,993 grams more than the second.

Answer:

Shark 1 weighs 80,993 grams more than the second.

The values have being matched to the variables that they represent here:

x-variable: the number of hours Sam works at the airport
y variable: the amount in dollars that Sam has after paying back Daniel
12: amount in dollars that Sam earns per hour.
40: the amount in dollars Sam owes Daniel

<h3>How to solve for the equation.</h3>

The equation of this form y = 12x-40

The variable y has been said to be the amount sam has after Daniel has been paid.

X is the amount that has to be multiplied by what he earns in dollars by the hour.

40 dollars is the amount that he owes which is going to be subtracted from what he earns by the hour.
