Answer:
x =
Step-by-step explanation:
<u>To solve quadratic systems,we always substitute one variable in terms if the other and then solve the equation.</u>
x + 2y = 6 ---------------(1)
y - 5 = ---------------(2)
y = + 5 ---------------(3)
Substitute (3) in (1) ,
x + 2( + 5 ) = 6
=
x + 2( + 5 ) = 6
--------------(4)
The roots of the quadratic equation is
x = -----------(5)
According to equation (5),solution of (4) is
x =
x =
x =

The amount of packing material is 1506 cubic inches
<h3>How to determine the amount of
packing material?</h3>
The given parameters are:
<u>Can</u>
Radius, r = 7 inches
Height, h = 18 inches
<u>Box</u>
Base dimension, l = 15 inches
Height, h = 19 inches
The volume of the can is:
So, we have:
The volume of the box is
So, we have:
The amount of packing material is;
Amount = V2 - V1
This gives
Amount = 4275 - 2769
Evaluate
Amount = 1506
Hence, the amount of packing material is 1506 cubic inches
