Answer:

2.(b) w= 3

3. x= -3 or x= 3

Step-by-step explanation:

2.(b) Method 1:

[tex] \frac{2w - 1}{5} + w + 2 = 2w \\ \frac{2w - 1}{5} = 2w - w - 2 \\ [/tex]

Simplify:

[tex] \frac{2w - 1}{5} = w - 2[/tex]

×5 on both sides:

[tex]2w - 1 = 5(w - 2)[/tex]

Expand:

[tex]2w - 1 = 5w - 10[/tex]

Bring constants to 1 side, w terms to the other:

[tex]5w - 2w = 10 - 1[/tex]

Simplify:

[tex]3w = 9[/tex]

Divide both sides by 3:

[tex]w = 9 \div 3 \\ w = 3[/tex]

Method 2:

[tex] \frac{2w - 1}{5} + w + 2 = 2w[/tex]

Multiply by 5 throughout:

[tex]2w - 1 + 5(w + 2) = 5(2w)[/tex]

Expand:

[tex]2w - 1 + 5w + 10 = 4w[/tex]

Simplify:

[tex]7w - 9 = 4w[/tex]

+9 on both sides:

[tex]7w = 4w + 9[/tex]

-4w on both sides:

[tex]7w - 4w = 9[/tex]

Simplify:

[tex]3w = 9[/tex]

Divide by 3 on both sides:

[tex]w = 3[/tex]

3. [tex] \frac{6x - 12}{3} + 4 = \frac{18}{x} [/tex]

Multiply by 3x on both sides:

[tex] \frac{3x(6x - 12)}{3} + 3x(4) = \frac{3x(18)}{x} \\ x(6x - 12) + 12x = 3(18)[/tex]

Expand:

[tex]x(6x) - x(12) + 12x = 54 \\ 6x^{2} - 12x + 12x = 54 \\[/tex]

Simplify:

[tex]6 {x}^{2} = 54[/tex]

Divide by 6 on both sides:

[tex] {x}^{2} = 9[/tex]

-9 on both sides:

[tex] {x}^{2} - 9 = 0[/tex]

Factorise:

*Since a²-b²= (a +b)(a -b),

[tex] {x}^{2} - {3}^{2} = 0 \\ (x + 3)(x - 3) = 0[/tex]

Thus,

x +3= 0 or x -3= 0

x= -3 or x= 3

Answer:

w = 3

Step-by-step explanation:

(6x-12)/3 + 4 = 18/x

Simplify fraction

2x -4 +4 = 18/x

Combine -4+4=0 Divide by 2 to reduce

x = 9/x

Multiply both sides by x

x² = 9

x = 3, -3

Answer:

$231,228.00

Step-by-step explanation:

100,000 * 52 = 520,000

520,000 * 0.4 = 208,000

8 * 52 = 416

416 * 1.75 = 728

208,000

+ 22,500

+       728

___________

$231,228.00

Answer: 7.5428

Step-by-step explanation:

I used a calculator.

Answer:

The answer is 3 inch

Step-by-step explanation:

To start off, the equation you want to use the formula V=whl

Next, you simply plug in the values you already know, so you have 450=w*20*7.5

After you do that you multiply 20 times 7.5 to get which is 150, which leaves you with 450= w *150 to solve for w, you need to isolate it. To do that you divide 450 by 150. You are left with the answer of 3.

answer: x=0.025253

Step-by-step explanation:

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

(0.25)

Step 1: Simplify both sides of the equation.

Step 2: Divide both sides by 1.885714.

1.885714x

1.885714

x=0.025253

The value of x from the given ratios 2 2/7 :(0.6x)= 4/21 :0.25 will be 5.

An equation is an expression that shows the relationship between two or more numbers and variables.

[tex]2 \frac{2}{7}[/tex] :(0.6x) = 4/21 :0.25

Therefore, solve the mixed fraction, we get

16/7 :(0.6x) = 4/21 :0.25

Step 1: Simplify both sides of the equation.

16/7 :(0.6x) = 4/21 :0.25

(16/7) / (0.6x) = (4/21 ) / (0.25 )

Step 2: Divide both sides

(16/7) / (0.6x) = (4/21 ) / (0.25 )

Cross multiply:

(16/7) x (0.25 )= (4/21 ) x (0.6x)

4/7 = 2.4x /21

84 = 16.8x

Divide both sides by 16.8:

x = 5

Answer:

first side = 33

second side = 20

third side = 37

Step-by-step explanation:

first side = 2x-7

second side = x

third side = (2x-7)+4

(2x - 7) + x + (2x - 7) + 4 = 90

5x - 14 + 4 = 90

5x - 10 = 90

     +10  +10

5x = 100

x = 20
