Answer:

Don caught 3.6 kg and Dan caught 0.6 kg.

Step-by-step explanation:

Set up a system of equations:

Don's fish is the variable a and Dan's fish is the variable b.

a + b = 4.2 (1)

a=6b          (2)

We can substitute a in the first equation using the second equation, so:

6b + b = 4.2

7b = 4.2

b = 0.6 kg

Dan caught 0.6 kg. Then, we can use equation 2 to find how much Don caught.

a = 6 x 0.6

a = 3.6

Don caught 3.6 kg.

Place the correct coefficients<br> x²y³ +<br> in the difference.<br> xy² +<br> y
antiseptic1488 [7]

The difference between the two polynomials is 11x²3y³ - 4xy².

<h3>What is the Difference between the Polynomials?</h3>

The difference between two polynomials is the result you get by subtracting one from the other.

Thus:

= (4x²2y³ + 2xy² – 2y) – (–7x²y³ + 6xy² – 2y)

= 4x²2y³ + 2xy² – 2y + 7x²y³ - 6xy² + 2y

= 11x²3y³ - 4xy²

Frank needs to save $600 to buy a set of golf clubs. He plans to save $75 per month. Write an equation that Frank can solve to d
Dmitrij [34]

Since, Frank needs to save $600 to buy a set of golf clubs. He plans to save $75 per month.

Now, we have to determine the amount of money still he has to save (y) in relation to the number of months (x) in which he has saved money.

Let 'y' be the amount of money he still have to svae.

Let 'x' be the number of months he has saved money.

Total money saved yet = $75 \times x= $75x

He has to save $600 in total.

So, Money he still have to save = 600 - 75x

So, y=600-75x is the required equation.
