Answer:<em><u> 2x - 4(x + 1) = 3x= -4/5</u></em>

<em><u /></em>

2x−4(x+1)=3x

2x+(−4)(x)+(−4)(1)=3x(Distribute)

2x+−4x+−4=3x

(2x+−4x)+(−4)=3x(Combine Like Terms)

−2x+−4=3x

−2x−4=3x

Step 2: Subtract 3x from both sides.

−2x−4−3x=3x−3x

−5x−4=0

Step 3: Add 4 to both sides.

−5x−4+4=0+4

−5x=4

Step 4: Divide both sides by -5.

<u><em>2x - 4x – 4 = 3x= -4/5</em></u>

2x−4x−4=3x

2x+−4x+−4=3x

(2x+−4x)+(−4)=3x(Combine Like Terms)

−2x+−4=3x

−2x−4=3x

Step 2: Subtract 3x from both sides.

−2x−4−3x=3x−3x

−5x−4=0

Step 3: Add 4 to both sides.

−5x−4+4=0+4

−5x=4

Step 4: Divide both sides by -5.

<em><u>-2x - 4 = 3x= -4/5 as well</u></em>

Answer:

Perimeter = 21 units

Volume = 110 cubic units

Step-by-step explanation:

Let the center of circle be (x,y).

(x+2)^{2} +(y-7)^{2} = (x)^{2}+(y+2)^{2}

4x - 18y = - 45

(x)^{2}+(y+2)^{2}=(x-2)^{2}+(y-2)^{2}

4x + 8y = 4

x + 2y = 1

Solving these 2 equations,

4 - 26y = -45

y = \frac{49}{26}

x = \frac{-36}{13}

radius = 3.35

Perimeter = 2\pi r = 21 units

Volume of cylinder = \pi r^{2} h

We have to add the volumes of the cylinders.

Volume of smaller cylinder = \pi \times 2^{2} \times 2 = 8\pi

Volume of larger cylinder = 27 \pi

Total volume = 35\pi = 110 cubic feet

Difference between 1 8/10 and 2 2/5
Eva8 [605]
The first step to solving this is converting these mixed numbers into improper fractions. You would do that by multiplying the denominator by the whole number and adding the numerator to that number; this number replaces the numerator. It would look something like this:

1 8/10   -->   18/10
2 2/5   -->   12/5

Now, to subtract the second fraction from the first one, the denominators of both fractions must be the same. We can make them the same by multiplying the second fraction by 2:

12/5 * 2/2 = 24/10

Now we can set up the equation as:

18/10 - 24/10 = -6/10   -->   -3/5

The answer is negative 3/5.

I hope this helps.

What is an equation of the line that passes through the points (4,3) and (7,3)​
Vika [28.1K]

Answer:

y = 3

Step-by-step explanation:

find out the slope

m = (3-3)/(4-7)

m = 0

so the line is horizontal

passing through the point (x,3)

x can be any value

so the equation is

y = 3
