1. 3x - 2y = 8 Subtract 3x on both sides

-2y = 8 - 3x Divide by -2 on both sides to get y by itself

y = -4 + 3/2x


2. a + b / 3 = 5 Multiply 3 on both sides

a + b = 15 Subtract a on both sides to get b by itself

b = 15 - a


3. 12x - 4y = 20 Subtract -12x on both sides

-4y = 20 - 12x Divide -4 on both sides to get y by itself

y = -5 + 3x


4. y + 3 = -5(x - 2) Multiply -5 to (x-2)

y + 3 = -5x + 10 Subtract 3 on both sides to get y by itself

y = -5x + 7

3x - 2y = 8 \\ - 2y = - 3x + 8 \\ y = \frac{3}{2} x + 4
can be applied for 1 ,3, and 4
\frac{a + b}{3} = 5 \\ a + b = 5 \times 3 \\ 15 - a = b

Nethan made 8 rose bouquets and 6 daffodil bouquets. Nethan only has enough flowers to make at most 20 rose or daffodil bouquets
Solnce55 [7]

Answer:

Nethan made 8 rose bouquets and 6 daffodil bouquets.

Nethan only has enough flowers to make at most 20 rose or daffodil bouquets total.

Let x represents the number of more rose bouquets.

Let y represents the number of more daffodil bouquets.

The maximum bouquets that can be made = 20

And the number of bouquets made are = 14

So, additional bouquets are = 20-14=6

In equation form we can show like :

x +y= 6

or y=6 -x

or x=6- y

Putting values of x as 0,2,4 and 6 we get:

When x = 0 then y = 6  

When x = 2 then y = 4

When x = 4 then y = 2

When x = 6 then y = 0

You can see the graph attached.

I'm confused with this, please help me. thanks ​
Eduardwww [97]

Answer:  17%

Step-by-step explanation:

I think they're saying your expenses for everything this month were $500, and of that $500 you spent $85 on clothing.

Let's represent the percentage spent on clothing as "\star". Then

$\star \% = \frac{85}{500}$

$\frac{\star}{100} = \frac{85}{500}$

which means

$\star = \frac{85}{500} \times 100 = 17$

(If you don't understand how I moved the 100, just think about it for a bit.)

So the answer is \boxed{17\%}.
