0= 8-2x divided by 5

Stells [14]

Answer:

Step 1: Simplify both sides of the equation.

0= 8− $\frac{2x}{5}$

0 = 8 + $\frac{-2}{5}x$

0 = $\frac{-2}{5}x+8$

Step 2: Flip the equation.

$\frac{-2}{5} x + 8=0$

Step 3: Subtract 8 from both sides.

$\frac{-2}{5} x+8-8=0-8$

$\frac{-2}{5} x=-8$

Step 4: Multiply both sides by 5/(-2).

$(\frac{5}{-2} ) *( \frac{-2}{5} x) = (\frac{5}{-2} )*(-8)$

<h2>Therefor, the answer is x=20</h2><h2 />

A barrel of crude oil contains about 5.61 cubic feet of oil. How many barrels of oil contained in 1 mile (5280 feet) of a pipeli

8_murik_8 [283]

1)volume of the pipeline

The pipeline is a cylinder, therefore;
Volume (cylinder)=πr²h
r=radius
h=height of the cylinder

diameter=6 in*(1 ft / 12 in)=0.5 ft
raius=diameter / 2=0.5 ft / 2=0.25 ft.
height=5280 ft

Volume (pipeline)=π(0.25 ft)²(5280 ft)=330π ft³≈1036.73 ft³.

2) we calculate the number of barrel
1 mile of oil in this pipeline is 330π ft³ of oil.

1 barrel of crude------------------5.61 ft³
x----------------------------------330π ft³

x=(1 barrel*330π ft³) / 5.61 ft³=184.8 barrels

3) we calculate the price.

1 barrel---------------$100
184.8 barrels---------- x

x=(184.8 barrels * $100) / 1 barrel=$18,480

Solution: ≈$18,480

Answer: $\frac{1}{b^6}$ or $b^{-6}$

Step-by-step explanation:

$\frac{b^-2+2}{b^4+2}$ Add the exponent two to both sides. After adding -2 and 2 you get 0 and any number raised to the zero power is one. And 4 plus two is 6
