Answer:

$x=-7$

Step-by-step explanation:

$-x+8+3x=-6$

$8+3x-x=-6$

$8+2x=-6$

$8+2x-8=-6-8$

$2x=-14$

$2x/2=-14/2$

$x=-7$

Answer:

x = -7

Step-by-step explanation:

Move over all the numbers and variables to one side and equal them to zero. The equation should now look like this: -x+8+3x+6=0

Combine like terms! Add -x+3x to get 2x and add 8+6 to get 14.

The equation should now read: 2x+14=0

Subtract 14 from both sides to show: 2x = -14

Get x by itself! Divide both sides by 2 to get x = -7

Cylinder E has the following dimensions: h = 30 cm and r = 4 cm. Cylinder F has the same radius, but has a height of 5 cm . What

Anarel [89]

Answer:

1759.52cm^3

Step-by-step explanation:

Given data

Cylinder E

h = 30 cm and

r = 4 cm

The expression for the volume is

V= πr^2h

V= 3.142*4^2*30

V= 3.142*16*30

V=1508.16 cm^3

Cylinder F

h=5 cm

r = 4 cm

The expression for the volume is

V= πr^2h

V= 3.142*4^2*5

V= 3.142*16*5

V=251.36 cm^3

Hence the total volume is

=251.36+1508.16

= 1759.52cm^3

An automobile traveling at the rate of 30 ft/sec is approaching an intersection. When the automobile is 120 feet from the inters

Trava [24]

Answer:

Distance between automobile and the truck is 100 feet.

Step-by-step explanation:

Speed of the automobile towards the intersection = 30 ft per sec

Speed of the truck that crosses the intersection = 40 ft per sec.

Automobile is 120 feet apart when the truck passes through the intersection.

After 2 seconds distance traveled by the automobile = Speed × time

= 30 × 2

= 60 feet

So the distance of the automobile from the intersection = 120 - 60

= 60 feet

Distance traveled by truck in 2 seconds = 40 × 2

= 80 feet

Now distance between them can be calculated by Pythagoras theorem

Distance = $\sqrt{(60)^{2}+(80)^{2}}$

= $\sqrt{3600+6400}$

= $\sqrt{10000}$

= 100 feet

Therefore, after 2 seconds distance between the truck and the automobile will be 100 feet.

Solve Equation<br> 1. 6 - 4x = 6x - 8x + 2

Helga [31]

Answer:

X=2

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6−4x=6x−8x+2

6+−4x=6x+−8x+2

−4x+6=(6x+−8x)+(2)(Combine Like Terms)

−4x+6=−2x+2

Step 2: Add 2x to both sides.

−4x+6+2x=−2x+2+2x

−2x+6=2

Step 3: Subtract 6 from both sides.

−2x+6−6=2−6

−2x=−4

Step 4: Divide both sides by -2.

−2x/−2=−4/−2

Step 5 :Answer

X=2
