Answer
Step-by-step explanation:
(15x-8y)=52
180=90+52+x
x=38
System of equations:
15x-8y=52
6x+14y=38
y=-6.5+15/8x
6x+14(-6.5+15/8x)=38
6x-91+26.25x=38
32.25x=129
x=4
15(4)-8y=52
60-8y=52
-8y=-8
y=1
x=4
Answer:
The system of the equations has no solution; the two lines are parallel.
Step-by-step explanation:
The equations have the same slope. In standard form, this can be seen as the same coefficients for x and y. We will multiply the second equation by -12 to reveal this.
This means the equations are parallel and will never cross. There is no solution.

Answer:
$3.90
Step-by-step explanation:
The total cost was $24.40.
We know the cost for beads for each necklace is also $2.20, multiply this by four to find the cost of the beads for all the necklaces.
$2.20 × 4 = $8.80
Now we will subtract this from the total price.
$24.40 - $8.80 = $15.60
$15.60 Is the remaining cost for the pendants of all four necklaces. We will now divide this by four to find the price of a single pendant.
$15.60 ÷ 4 = $3.90
<u>This means the cost of each pendant is $3.90</u>
