Answer:

Step-by-step explanation:
We can write the following system of equations:

Adding both equations together, we isolate
and get:

Plugging
in any of the equations, we can solve for
:

Verify that the solution pair
works 
Therefore, the two numbers are
.
#5: cost: y
Number of beads: x
y=0.48*x
So for 4 beads: 1.92
for 5 beads: 2.4
#6: the x th term in the sequence is y
y=17-2x
The 10th term is -3
Answer: 7 1/30
Step-by-step explanation: convert to improper fractions then find lowest common denominator between them then add and simplify back to mixed fraction :)
