Let
x = the number of tapers (each coss $1)
y = the number of pillars (each costs $4)
z = the number of jars (each costs $6)
There are 8 candles in each basket, therefore
x + y + z = 8 (1)
The cost per basket is $24, therefore
x + 4y + 6z = 24 (2)
The number of tapers equals the sum of pillars and jars, therefore
x = y + z (3)
Substitute (3) into (1) and into (2).
y + z + y + z = 8
2y + 2z = 8
y + z = 4 (4)
y + z + 4y + 6z = 24
5y + 7z = 24 (5)
From (4), y = 4 -z. Substitute into (5).
5(4 - z) + 7z = 24
2z + 20 = 24
2z = 4
z = 2
y = 4 - z = 4 - 2 = 2
x = y + z = 2 + 2 = 4
Answer: 4 tapers, 2 pillars, 2 jars.
Answer:
20 Tshirts
Step-by-step explanation:
Tshirts = $7.90 each
Shipping = $2
Total amount = $160
Amount of tshirts bought = y
7.90y + 2 = 160
7.90y = 160 -2
7.90y = 158
Divide both sides by 7.9
y = 158÷7.9
y = 20
Candice's bracelet is made from silver because the volume of her bracelet is; 1.72cm³
<h3>Density, Mass and Volume</h3>
By definition, the density of an object is the ratio of its mass per unit volume.
Hence, for silver;
Volume = 1.72cm³.

Answer:
11.46 meters
Step-by-step explanation:
12min 30sec = 12.5min
55km/h * 12.5min * 1h/60min = 11.4583333333meters
Answer:
100 minutes
Step-by-step explanation:
Let
x ----> the number of minutes
y ----> the total cost of the plan
we know that
<em>Cingular Plan</em>
-----> equation A
<em>Verizon Plan</em>
-----> equation B
To find out how many additional minutes will it take for the two plans to cost the same
Solve the system of equations A and B
Solve by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (100,84.99)
see the attached figure
therefore
For x=100 minutes
The cost for both plans is $84.99
