Answer:

x = -3

Step-by-step explanation:

  8-4*x-(20)=0

Pulling out like terms

  -12 - 4x  =   -4 • (x + 3)

   -4   =  0

  x+3 = 0

Subtract  3  from both sides of the equation :

                     x = -3

P is inversely proportional to V.<br> When V = 8, P = 5<br> Find a formula for Pin terms of V.
AveGali [126]

Answer:

P = \frac{40}{V}

Step-by-step explanation:

given P is inversely proportional to V then the equation relating them is

P = \frac{k}{V}

to find k use the condition when V = 8 , P = 5 , then

5 = \frac{k}{8} ( multiply both sides by 8 to clear the fraction )

40 = k

P = \frac{40}{V} ← equation of proportion

Brian is going camping and. is making a tent from fabric. How much fabric will he need? 6 ft. 12.5 ft. 8.5 ft.​
Alona [7]

Answer and explanation:

Depending on the type and size of tent you wish to make, an average tent should consume more than 12.5ft of fabric. You would require more than 10 yards of fabric to make a small tent that an adult human being can fit in.

1 yard = 3 ft

And so you would require about 30 ft of fabric to make your tent. Therefore the options listed may not be enough fabric to make a tent
