A= \frac{1}{2} h (x+y)

we have to solve for x , solving for x means , we have to isolate x one one side , by shifting all other variables to other side

So

A= \frac{1}{2} h (x+y)

Multiply both sides by 2

2A = h(x+y)

Divide both sides by h

2A/h = x+y

Subtract y from both sides

\frac{2A}{h}  -y =x

or

x=\frac{2A}{h}  -y

Mama L [17]

Answer:

If we define S as the number Sprinkle's umbrellas, and H as the Hurricane's umbrellas, the profit P can be expressed as:

P=3S+5H

The restriction for cloth can be written as:

S+2H\leq500

The restriction for metal can be written as:

2S+3H\leq600

The restriction for wood can be written as:

4S+7H\leq800

The condition for S and H to be positive is:

S, H \geq0

Step-by-step explanation:

We have an objective function that, in this case, we want ot maximize.

This function is the Profit (P).

If we define S as the number Sprinkle's umbrellas, and H as the Hurricane's umbrellas, the profit can be expressed as:

P=3S+5H

We have 3 restrictions, plus the condition that both S and H are positive.

The restriction for cloth can be written as:

S+2H\leq500

The restriction for metal can be written as:

2S+3H\leq600

The restriction for wood can be written as:

4S+7H\leq800

The condition for S and H to be positive is:

S, H \geq0

The largest angle in a triangle is three times as big as the smallest angle, and the middle angle is twice as big as the smalles
PtichkaEL [24]
Let X = smallest angle
largest 3x
middle=2x. add the 3 angles of any triangle and you get ,180

x+2x+3x=180
6x=180
x= 30
smallest =30
middle=60
largest=90

Make up a story to go with the graph. You can refer to the line segments by color or number.
9966 [12]
First, Joe started the water and it was at full force. He filled it up to 9 inches. It took him 2 minutes to get to 9 inches. Then, he stopped it for 2 minutes because his mom called him to get a bar of soap. The water level was still at 9 inches when he stopped it. Then, he put the water to come down slowly because he wasn’t sure how much more he needed. He let the water go for 2 minutes. Then, he stopped the water when it was at 12 inches of water. He sat in the bath for 5 minutes until he decided he was to cold so he hopped out. The water then drained really fast. From 12 inches to 0 inches it took the bath 3 minutes.

The area of a playground is 336 yd2. The width of the playground is 5 yd longer than its length. Find the length and width of th
kondaur [170]
L=16
W=21

Set up a systems of equations: 
x=length 
y=width 

xy=336
x+5=y

Use substitution to solve: 
x(x+5)=336
x^2+5x=336 

Solve using factoring: 
x^2+5x-336=0
(x-16)(x+21)=0
x=16 and x= -21 
Since length can't be negative, l=16 

To find width, plug length into the first equation: 
(16)y=336
y=21 

So...
L=16
<span>W=21</span>
