Mathematics Middle School

You are in the band room when a shipment of new trumpets and trombones arrives. Your music teacher asks you to make sure the order is right. All the boxes are about the same size, so you find the number of boxes in the shipment. There are 27 total boxes. The bill shows the school paid $10,950. In the catalogue, the price of a new trumpet is $350 and the price of a new trombone is $475.
1. Write an equation representing the total number of instruments.
2. Write an equation representing the total cost.
3. Using your equations from Exercises 1 and 2, write and solve the linear system using substitution.
4. How many trumpets did your school receive? How many trombones?
5. Check your results by graphing your linear system.

The answer to this question is the one on the left then the right then the one sign is the correct answer

Answer: 35x+20≥1,000; x ≤28

Explanation:

There is already 20 bags and 35 bags are filled per hour. So 35 is the rate of change and 20 is the constant

35x+20 ≥1,000
-20 -20

35x ≥980
Divide both sides by 35 to isolate x
=28

Flip the sign because you divided

x≤28

If a hen and a half lay an egg and a half in a day and a half, how many eggs will half a dozen hens lay in half a dozen days?

Good Luck!! First correct answer MIGHT get brainliest!!

Answers

Answer:

72 eggs

Step-by-step explanation:

Let’s simplify the answer: if one and a half hens lay an egg in 18 hours, how many eggs will 6 hens lay in 6 days? So 18/3=6, and 6x2=12. One hen can lay an egg in 12 hours. Which means a hen can lay 2 eggs in one day. 2x6=12. So 6 hens can lay 12 eggs in one day. 12x6=72. In 6 days, 6 hens can lay 72 eggs

Oh I answered first btw if you’re wondering later

Answer:

4 eggs

Step-by-step explanation:

One and half hen=1 egg in two days

=3 hens(one and half +one and half)=two eggs in four days

6 hens(half a dozen is equal to 12 divided by 2=6)=? Eggs in six days

=the 6 hens divided by 3 hens =2

The two eggs gotten from the 3 hens + the other 2=4 eggs in six days

What it is showing is that you need 6 faces to make one bottle. So, if the problem is how many faces are in 6 bottles then you would explain multiplying the 6 by 6 to get 36. But I’d the problem is how many bottles can you make with __ faces then you use the two sentences to explain dividing. I am going to go with my first example to show you what it could look like. “What is it showing is that you need 6 faces to make 1 bottle. So 6x6=36. So, the answer is 36.” :)
