Answer: <em>3w+4b</em>
Step-by-step explanation:
<em>Take your given equation</em>
<em>w+w+w+b+b+b+b</em>
<em>There are 3 w's and 4 b's</em>
<em>Combine like terms</em>

<em>b+b+b+b=</em><em>4b</em>
<em>3w+4b</em>
X2-64=0
x2=64
x=8 because when multiplied by itself, and plugged back in, it works
1/6 + 1/12 = 1/4
If you need me to explain how I got the answer I am more than happy!
I hope this helps!
5x + 10y = 800
y = 50
10y = 10*50 = 500
800 - 500 = 300
300/5 = 60
x = 60
5(60) + 10(50) = 800
60 small vehicles were washed in total
Answer:
The length is 10 yards and the width is 20 yards of the playground.
Step-by-step explanation:
Given,
Area of the rectangular playground = 200 yards.
Solution,
Let the length of the playground be x.
Then the width of the playground is 2x.
Now, According to the formula of area of rectangle;

On substituting the values, we get;

So the length of the playground is 10 yards.
Since the width is twice of the length.
So width = 
Hence the length is 10 yards and the width is 20 yards of the playground.
