Answer:

x = 32

Step-by-step explanation:

If x and y vary inversely, then xy = k where k is the constant of proportion

4(8) = 32 = k

Now, xy = 32

1(x) = 32

x = 32

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

$X=288.5ft$

From the question we are told that:

Number of tables $n=36$

Length of table $l=8$

Extension $e=3 inch =>0.25feet$

Generally, the equation for the Total length tables is mathematically given by

$l_t=n*l\\\\l_t=36*8$

$l_t=288ft$

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

$X=l_t+2(e)\\\\X=288ft+2(0.25)$

$X=288.5ft$

In conclusion

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

$X=288.5ft$

Answer:

EF=6

Step-by-step explanation:

E is the midpoint, so DE = EF

DE = 15-3x

EF = x+ 3

Since DE = EF,

15 - 3x = x + 3

-4x = -12

x = 3

If x = 3,

DE = 15 - 3*3, 15 - 9 = 6

EF = x+ 3, so EF = 3 + 3 = 6
