4d + 3d = 7d so 7d + 15 would be the expression for both except it would only be 3d + 4d = 7d and 7d + 15 is the same as the first expression that I got from evaluating 4d + (15 + 3d).

Answer:

x=-4

Step-by-step explanation:

3x-5=7x+11    Add like terms

   +5     +5

3x=7x+16       Do it again...

-7x   -7x

-4x=16        Now divide

x=-4

Answer:

The answer is x=-4

Step-by-step explanation:

3x-5=7x+11

1) you have to move the number that has a variable with it onto one side(3x and +7x) and the numbers that do not have a variable move them onto the other side (-5 and +11),but if you move them you have to change the sign like the underlined numbers below

3x-7x=5+11

2) you have to subtract 3x and-7x which it equals  -4x and then you have to add 5 and 11 which it equals 16

Equation now -4x=16

3) you have to divide -4x into -4x and also divide -4x into 16 which you will get x=-4

Hope it helps out! :)

Step-by-step explanation:

add the the ones above 80% and higher

maybe try -5 since the rise/run is 5/1 and the slope is negative

The slope of the graphed line is m = -5

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the first point be P ( 0 , 2 )

Let the second point be Q ( 2 , -8 )

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = ( 2 - ( -8 ) ) / ( 0 - 2 )

m = 10 / -2

m = -5

Hence , the slope is m = -5

Answer:

Height, h = 9 m

Step-by-step explanation:

Given that,

The volume of a water tank, V = 254.34 m³

The diameter of the tank, d = 6 m

We need to find the height of the clinder. The volume of a cylinder is given by :

[tex]V=\pi r^2h\\\\h=\dfrac{V}{\pi r^2}\\\\h=\dfrac{254.34}{3.14\times (3)^2}\\\\h=9\ m[/tex]

Answer:

Step-by-step explanation:

Answer: All real numbers are solutions.

Step-by-step explanation:

Let's solve your equation step-by-step.

2(3x−1)=6x−2

Step 1: Simplify both sides of the equation.

2(3x−1)=6x−2

(2)(3x)+(2)(−1)=6x+−2(Distribute)

6x+−2=6x+−2

6x−2=6x−2

Step 2: Subtract 6x from both sides.

6x−2−6x=6x−2−6x

−2=−2

Step 3: Add 2 to both sides.

−2+2=−2+2

The second to last option

Step-by-step explanation:

imagine that the diagram only shows part of each line, or edge. instead, they extend forever in both directions. imagining RQ extending to both sides lets you find other "extended" intersecting lines. in this case, QU and SR

here is an example in ascii art:

___________

|                         |

|___________|

Imagine that the separated lines are instead all sides of a rectangle. My ascii is limited.

Nothing here intersects

__|______________|__

now you can see intersecting lines. so you can answer the question correctly.

Answer:

5. k=−3

6.  x=4

7. n=−108

Step-by-step explanation:

5. -14k+29=71

Subtract 29 from both sides

-14k+29-29=71-29

Simplify

-14k=42

Divide both sides by -11

-14k/-14=42/-14

6. -33=19-13x

Subtract 29 from both sides

-14k+29-29=71-29

Simplify

-14k=42

Divide both sides by -14

-14k/-14=42/-14

Simplify

k=-3

7. 8+n/25=-4

Multiply both sides by 25

25(8+n)/25 = 25 (-4)

Simplify

8+n=-100

Subtract 8 from both sides

8+n-8=-100-8

Simplify

n=-108

Answer:

  x = -2 because that is the value that makes the equation true

Step-by-step explanation:

Minus signs are everywhere. They can all be eliminated by multiplying both sides of the equation by -1.

  -1(-x -6 -x) = -1(-2)

  (-1)(-x) +(-1)(-6) +(-1)(-x) = 2 . . . . . distribute the -1

  x + 6 + x = 2 . . . . . . . . simplify

  x + x + 6 = 2 . . . . . . . . rearrange

  (1 +1)x +6 = 2 . . . . . . . . factor, using the distributive property

  2x +6 = 2 . . . . . . . . . . . simplify

  2x +6 -6 = 2 -6 . . . . . . subtract 6 from both sides

  2x = -4 . . . . . . . . . . . . . simplify

  (2x)/2 = (-4)/2 . . . . . . . divide both sides by 2

  x = -2 . . . . . . . . . . . . . . simplify

x is -2 because that is the value we get when we apply the properties of equality to the equation. We can check to see if it works in the original equation.

Check

-x -6 -x = -2

-(-2) -6 -(-2) = -2 . . . . put -2 where x is

2 -6 +2 = -2 . . . . . . . . simplify the signs

-4 +2 = -2 . . . . . . . . . . add the first two terms (could do all at once)

-2 = -2 . . . . . . . . yes, the value of x=-2 makes the equation true

Additional comment

The properties of equality we're concerned with here are the multiplication property of equality, the addition property of equality and the division property of equality. Respectively, these tell us that multiplying, adding, or dividing both sides of the equation by the same number doesn't change the value of the variable.

These properties are essential to understanding how algebra works.
