Answer:

1,333 frogs

Step-by-step explanation:

okay so we know that mass remains conserved no matter where you are.

same here ^^

if the total mass of brass is 200 kg

the total mass of the new frogs formed from it when put together will be the same :)

and if there were n such frogs formed

we have,

total mass = n × mass of each frog

200 = n × 3/ 20

n = 4000/ 3

so it becomes something like 1,333.33

that is nearly 1,333 frogs can be made out of 200 kg of brass each weighing 3/ 20kg (the last ones a bit less to make upto 200kg)

So when you're solving for x here and distribute 8 on the right side, it would look like this:

$8x+47=8(x+5)\\ \\ 8x+47=8x+40$

Now in order to solve for x, we know we have to get all the x's on one side of the equal sign. Let's get all our x's to the left side. Since the right side has a positive 8x, you need to subtract 8x on the right. But whatever you do to one side you must do to the other. So since we are subtracting 8x on the right, we need to do that on the left.

But we can't! Since both sides will cancel out to zero before x can be solved.

Therefore the answer is 0.

Hope that helps!

We expect that students who do well on the midterm exam in a course will usually also do well on the final exam. Gary Smith of P

Using the model equation, the predicted mean score on the final given a score of 10 points above the class mean in the mid term exam is 50.7
