n = 27

Answer:

n = 27

Step-by-step explanation:

(2n + n)÷9 = 9

multiply both side by 9

(2n + n) = 81

3n = 81

Divide both sides by 3

3n/3 = 81/3

n = 27

Answer:

22, 23, 24, and 25.

Step-by-step explanation:

The sum of four consecutive integers is 94, and we want to determine the integers.

Let x be the first integer. Since they are consecutive, the second will be (x + 1), the third (x + 2), and the fourth (x + 3).

They sum to 94. Hence:

[tex]\displaystyle x + (x+1) + (x+2) + (x+3) = 94[/tex]

Solve for x. Combine like terms:

[tex]4x + 6= 94[/tex]

Subtract:

[tex]\displaystyle 4x = 88[/tex]

And divide. Hence:

[tex]\displaystyle x = 22[/tex]

Therefore, the first term is 22.

Then the four integers are 22, 23, 24, and 25.

Answer:

= -2

Step-by-step explanation:

6t + 3 (1 - 2t) - 5

= 6t + 3 - 6t - 5

6t and -6t cross out as they equal 0, so we are left with only +3 and -5

+3 - 5 = -2

= -2 ---> final solution

Step-by-step explanation:

if AD =17,then Dc is also 17 because from the diagram,it is given that AD=DC.

And because AD and DC are equal,it means AC = AD +DC,therefore AC = 17+17,AC =34

AC=2y-6

therefore

34=2y-6

28=2y and y=14

Answer:

Step-by-step explanation:

First:

F=m.a

=4*7

=28N

Second:

F=m.a

28=m.2. (force is constant,so F=28N)

28/2=m

m=14kg.

Answer:

First:

F=m.a

=4*7

=28N

Second:

F=m.a

28=m.2. (force is constant,so F=28N)

28/2=m

m=14kg.

Answer:

r = 9

Step-by-step explanation:

These are vertical angles, therefore, the measurements is the same. Set the two measurements equal to each other:

7r - 5 = 6r + 4

Isolate the variable, r. Note the equal sign, what you do to one side, you do to the other. Add 5 and subtract 6r from both sides of the equation:

7r (-6r) - 5 (+5) = 6r (-6r) + 4 (+5)

7r - 6r = 4 + 5

Simplify:

7r - 6r = 4 + 5

r = 9

9 is your value for r.

Answer:

w = -13

Step-by-step explanation:

4w - 41 = 7(w-2)

Open the bracket

4w -41 = 7w -14

Collect like terms

4w - 7w = 41 - 14

-3w = 27.

Divide both side by -3

w = -9

Answer: w = 5

Step-by-step explanation:

4w-41=-7w+14

4w+7w=14+41

11w=55

W = 55/11

W = 5

Answer:

x = 4/7

Step-by-step explanation:

x^3 = 64/ 343 // - 64/ 343

Answer:b

Step-by-step explanation:

The area of the quadrilateral with the given coordinates is 27 square units.

The coordinates of the quadrilateral are A(0, 4), B(5, 2), C(3, -3) and D(-2, -1).

We need to find the area of the quadrilateral with the given coordinates.

The formula to find the area of the quadrilateral with coordinates ( x₀, y₀ ), ( x₁, y₁ ), ( x₂, y₂ ), ( x₃, y₃ ) is (1/2) × ( x₀y₁ - x₁y₀ + x₁y₂ - x₂y₁ + x₂y₃ - x₃y₂ + x₃y₀ - x₀y₃ ).

Now, Area=1/2×(0×2-5×4+5×(-3)-3×2+3×(-1)-(-2)×(-3)+(-2)×4-0×(-1))

=1/2×|(-20-15-6-3-6-8)|=27 square units.

Therefore, the area of the quadrilateral with the given coordinates is 27 square units.
