The correct answer is A. 10 bracelets
2x + 2(5+x)=10
2x+10+2x=10
4x+10=10
4x=0
X=0
The answer is a = 
Step-by-step explanation:
<em>1. Convert the mixed fraction to an improper fraction</em>
To find the numerator, multiply the denominator by the whole number and add the numerator to it.
The denominator remains the same.
So, 2
will be 
<em>2. Now the equation is,</em>
a -
a =
+
a
<em>3. Take LCM on both sides. </em>
For the left side, multiply the first fraction by
and multiply the second fraction by 
a -
a = 
<em>4. Solve by making a the subject</em>
= 
= 
=10+8a
= 10 + 8a
a = 2(10 + 8a)
a = 20 + 16a
a-16a = 20
-15a = 20
a = 
a = 
Therefore, the answer is a =

Answer:
round answer is : 10 ft
Step-by-step explanation:
The explanation is in the picture!
The two lines are parallel, therefor 90-28=internal angle=62. Using trigonometry, Cosine=a/h. Cos(62)=350/x. Rearrange to get 350/Cos(62) = 519.7(1dp)
