The equation is 
Step-by-step explanation:
The bracket is denoted by the variable x.
The necklace is denoted by the variable y.
From given, Linda sells her bracket for $6.
Thus, the expression for bracket is 
.
Also, Linda sells her necklace for $10.
Thus, the expression for necklace is 
.
The equation for Linda sells her bracket and necklace is
Answer:
6 1/2
Step-by-step explanation:
i don't know the rest but I know that that one might be 6 1/2
the correct answer for this is the last choice:
It is incorrect because the length of the unknown side is the square root of 7,225.
Good news: they are all like terms
9x + 5x -3x -8x = 3x
Answer:
1) ΔACD is a right triangle at C
=> sin 32° = AC/15
⇔ AC = sin 32°.15 ≈ 7.9 (cm)
2) ΔABC is a right triangle at C, using Pythagoras theorem, we have:
AB² = AC² + BC²
⇔ AB² = 7.9² + 9.7² = 156.5
⇒ AB = 12.5 (cm)
3) ΔABC is a right triangle at C
=> sin ∠BAC = BC/AB
⇔ sin ∠BAC = 9.7/12.5 = 0.776
⇒ ∠BAC ≈ 50.9°
4) ΔACD is a right triangle at C
=> cos 32° = CD/15
⇔ CD = cos32°.15
⇒ CD ≈ 12.72 (cm)
