Answer:
A piece of Jewelry costs $4.5 and a hair accessory costs $1.5.
Step-by-step explanation:
Let the price of a piece of jewelry is $x and that of a piece of hair accessories is $y.
So, from the given conditions we can write two different equations as
5x + 8y = 34.5 ............ (1) and
2x + 16y = 33 ............... (2)
Now, solving the equations (1) and (2) we get
2x + 2(34.5 - 5x) = 33
⇒ 8x = 36
⇒ x = $4.5
Again, from the equation (2) we can write
2(4.5) + 16y = 33
⇒ 16y = 24
⇒ y = $1.5
Therefore, a piece of Jewelry costs $4.5 and a hair accessory costs $1.5. (Answer)
Answer:

Answer:
(0, 15)
Step-by-step explanation:
y -intercept is obtained at x = 0
- 3x + 2y = 30
- 3*0 + 2y = 30
- 2y = 30
- y = 15
Coordinates of y- intercept: (0, 15)
Answer: 10
Step-by-step explanation:
2x+46+3x-6=90 degrees
5x+40=90 degrees
5x = 50 degrees
x = 10 or 10 degrees
