We have that the total length of paper needed to cover all the tables is

From the question we are told that:
Number of tables 
Length of table
Extension 
Generally, the equation for the Total length tables is mathematically given by


Therefore with an extension of 0.25ft at both end we have the Total length of tablecloths to be


In conclusion
The total length of paper needed to cover all the tables is

What you do to on side of an equation (=) you must do to the other to keep both sides equal.
r3-2+2=+2 (add 2 to both sides of the equation to simplify the left side)
which becomes
r3=2
r3/3 = 2/3 (divide both sides by 3) Note 3/3 =1 and 1 r is the same as r
which becomes
r=2/3 .
Answer:
-2
Step-by-step explanation:
4y - 7 = - 15
4y = -15 + 7
4y = -8
y = - 8 / 4
y = - 2
