Rearrange 2y = 3(2+x) make x the subject

Answer:

x =5

Step-by-step explanation:

Using the formula for calculating the distance between two points

D = √(x2-x1)²+(y2-y1)²

Given the points A(2, x) , B(x, 8) and AB = 3√2

On substituting the given values into the formula;

AB = √(x-2)²+(8-x)²

3√2= √(x-2)²+(8-x)²

square both sides

(3√2)²= (x-2)²+(8-x)²

18 = (x-2)²+(8-x)²

expand

18 = x²-4x+4+64-16x+x²

18 = 2x²-20x+68

2x²-20x+68-18 = 0

2x²-20x+50 = 0

x²-10x+25 = 0

Factorize

x²-5x-5x+16 = 0

x(x-5)-5(x-5) = 0

(x-5)(x-5) = 0

x-5 = 0 an x-5 = 0

x = 5

Answer:

3x+10

Step-by-step explanation:

Plug n(x) into the x of the m(x) and the answer is m(n(x)).

m(x) = 3x - 2

n(x) = x + 4

Plug in n(x) to m(x) as shown here

m(n(x)) = 3(x + 4) - 2

distribute the 3

m(n(x)) = 3x + 12 - 2

simplify

m(n(x))= 3x + 10

Given:

Aisha has 3 pizzas.

She is serving each person at a party 1/4 of a pizza.

To find:

The number of people she can serve at the party.

Solution:

Let the number of people be x.

Number of pizzas is 3. So, each person get [tex]\dfrac{3}{x}[/tex] part of pizza.

It is given that each person get 1/4 of a pizza.

[tex]\dfrac{1}{4}=\dfrac{3}{x}[/tex]

Using cross multiplication, we get

[tex]1\times x=3\times 4[/tex]

[tex]x=12[/tex]

Therefore, the number of persons in 12.

Now, divide the number line in four equal parts between each pair of consecutive integers.

Then, count the marked points from 0 to 3 excluding 0. These points represent number of persons.

Answer:

Step-by-step explanation:

3w + 12 + 2w = 27

5w + 12 = 27

5w = 15

w= 3

Step-by-step explanation:

Answer:

X = 5

Step-by-step explanation:

For the equilibrium position of the scale,

Weights on both the sides of the scale should be equal.

Weights on left side of the scale = Weights on the right side

Weights denoting X + Weights denoting (-1) = Weights denoting (X) + Weights denoting (1)

5(X) + 6(-1) = 3(X) + 4(1)

5X - 6 = 3X + 4

5X - 3x = 6 + 4

2X = 10

X = 5

Therefore, For X = 5, scale will be in the balanced position.

Step-by-step explanation:

Answer:

h = (A - 9)/6

Step-by-step explanation:

Step 1: Define

A = b² + 2bh

b = 3

Step 2: Substitute

A = (3)² + 2(3)h

Step 3: Evaluate and solve for h

A = 9 + 6h

A - 9 = 6h

(A - 9)/6 = h

Jk just trying to get brainly points

Answer: 13 hours

Step-by-step explanation:

Money earned per hour = $11.00

Amount he plans to earn = $143. 00

Number of hours he will have to work to reach his goal = 143.00/11.00 = 13.

Therefore, Bryon will have to work of 13 hours to earn $ 143.00

Answer:

13 hours!

Step-by-step explanation:

All I did was divide $143.00 by $11.00 and got 13!

Or you could multiply $11.00 by 13 to get $143.00

They give you the same answer!! :D

Answer:

The answer would be C.

Answer:

  real numbers, including the boundary lines

Step-by-step explanation:

The inequality symbols in this system both include the "or equal to" case, so the boundary lines of the "shaded area" are part of the solution set.

Ordinarily, weight is a continuous variable, so we presume the weights of almonds and cashews may be any real number. The problem statement gives no clarity in that regard, so it is entirely possible that the given nuts will only be delivered in packages with integer weights.

Based on our presumption, the solution set is best described as below.

_____

Additional comments

Each inequality gives rise to a "shaded region," as shown in the second attachment. The solution set will be the doubly-shaded region, limited to the first quadrant. (Quantities of nuts cannot be negative.) Strictly speaking, the answer choices are all incorrect.

Step-by-step explanation:

just because

Step-by-step explanation:

f(x) = x³ - ax² - 13x + b.

f(1) = 1³ - a(1)² - 13(1) + b = 0

=> 1 - a - 13 + b = 0, b - a - 12 = 0.

f(-3) = (-3)³ - a(-3)² - 13(-3) + b = 0

=> - 27 - 9a + 39 + b = 0, 12 - 9a + b = 0.

Therefore, b - a - 12 = 12 - 9a + b. 8a = 24, a = 3.

=> b - (3) - 12 = 0, b = 15.
