A Guide to Packing Tape
Packing Tape/Packaging Tape- Considered a pressure sensitive tape used in a wide variety of applications, commonly used for sealing boxes and packages for shipments. The most common widths are two to three inches wide and made from a polypropylene or polyester backing. Other pressure sensitive tapes include:
Transparent Office Tape- Commonly referred to as "Scotch tape" is one of the most commonly used tapes in the world. Used for a variety of applications including sealing envelopes, repairing torn paper products, holding light objects together, etc.
Gaffers Tape- A heavy fabric or plastic tape. Commonly used in the entertainment industry to hold down cables and chords. The adhesive leaves little residue and removes cleanly from objects.

Electrical Tape- Commonly made of vinyl it is designed to stretch and conform to irregularly shaped surfaces. Used to help wrap electrical wires to protect them from the elements.
Answer:
b
Step-by-step explanation:
Let x and y be the speeds of the two points. The circle is of length 120m that is Circumference of circle is 120m.When the points are moving in opposite directions, they meet in every 15 seconds.That is the points cover 120m in 15 seconds.As they are moving in opposite directions, so the relative speed will be equal to the sum of speeds of both points.Speed= Distance ÷Time = 120÷15=8m per seconds.
x+y=8
When going in the same direction, one point catches up to the second every 60 seconds.Speed= 120÷60=2 m per seconds
x-y=2.
Solving the two equations by elimination method:
x+y=8.
x-y=2
Adding the equations:
2x=10 ,x=5m / sec.
x+y=8
5+y=8
y=3m/sec.
Thus, the speed of the two points is 5 m/s and 3 m/s.
Answer:
Let's solve for a.
2(3x+4)=ax+b
Step 1: Flip the equation.
ax+b=6x+8
Step 2: Add -b to both sides.
ax+b+−b=6x+8+−b
ax=−b+6x+8
Step 3: Divide both sides by x.
ax
x
=
−b+6x+8
x
a=
−b+6x+8
x
