10 / 10+x = 35 / 56
560 = 350 + 35x
35x = 560 - 350
35x = 210
x = 210/35
x = 6
So, your final answer is 6
Hope this helps!
The profit is going to be the total amount made, so you are going to subtract $350 - $45 = $305. $305. I hope this helps!
We are given
number of heads =15
we know that
any healthy dragon has three heads
horse has 1 head
chicken has 1 head
Let's assume
number of dragons is x
number of horses is y
number of chickens is z
so, we will get
first equation:

number of legs =50
any healthy dragon has four legs
chicken has 2 legs
horse has four legs
so, we can get second equation as

we can simplify it


now, we can find third equation
dragon has two wings
horse has no wings
chicken has two wings
so, we will get third equations as

now, we can simplify it



so, we will get system of equations as



now, we can use substitution
We can find for z from third equation

we can plug this in first equation

now, we can solve for y


now, we can plug this z and y into second equation

now, we can solve for x



now, we can find y and z

we can plug x=1



we can plug x=1


Hence ,
number of dragons is 1
number of horses is 11
number of chicken is 1............Answer
Answer:
1. 6x^2 + 4x - 4y
2. x - 10y.
3. 6x^5
4. 36 a^6 b^8
5. x^2 - 81
6. 9x^2 - 42x + 49
7. 12x^2 +3x - 42
Step-by-step explanation:
1. 3x^2+4x+3x^2-4y
Add the like terms, we get
6x^2 + 4x - 4y
2. (5x-2y)-(4x+8y)
Now distribute the negative sign, we get
5x - 2y -4x -8y
Simplify the like terms, we get
x - 10y.
3. 3x^3(2x)^2
Multiply the numbers and simplify the variables
6x^(3 +2)
6x^5
4. (-6a^3b^4)^2
Now bring the power 2 inside the parenthesis.
-6^2 a^6 b^8
= 36a^6b^8
5. (x+9) (x-9)
x^2 + 9x -9x - 81
x^2 - 81
6. (3x-7)^2
(3x - 7)(3x - 7)
9x^2 - 21x -21x + 49
9x^2 - 42x + 49
7. (3x+6) (4x-7)
12x^2 + 24x -21x - 42
12x^2 +3x - 42
Thank you.
