Answer:

8

Step-by-step explanation:

6x+1 = 9x-23

add 23 to both sides

subtract 6x from both sides

3x=24

x=8

Answer:

8 =x

Step-by-step explanation:

The angles are the same so

6x+1 = 9x-23

Subtract 6x from each side

6x+1-6x = 9x-6x-23

1 = 3x-23

Add 23 to each side

1 +23 = 3x-23+23

24 = 3x

Divide by 3

24/3 = 3x/3

8 =x

Answer:

x = - 2, x = 3

Step-by-step explanation:

Given

x² - x - 6 = 0

Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (- 1)

The factors are + 2 and - 3 , since

2 × - 3 = - 6 and 2 - 3 = - 1 , then

(x + 2)(x - 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 3 = 0 ⇒ x = 3

Answer:

the longest side of the first triangle is 32 cm

Step-by-step explanation:

Given;

dimension of the smaller triangle =  4.5cm 6cm and 8 cm.

the longest side of this smaller triangle = 8 cm

Perimeter of the first triangle = 74 cm

let the increase in dimension of the similar first triangle = x

the longest side of the first triangle = 8x

4.5x + 6x + 8x = 74

18.5x = 74

x = 74/18.5

x = 4

the longest side of the first triangle = 8 x 4 = 32 cm

Answer:

x = 30

Step-by-step explanation:

The exterior angle is equal to the sum of the opposite interior angles

4x-18  = 2x+6 + 36

Combine like terms

4x-18 = 2x+42

Subtract 2x from each side

4x-18-2x =2x+42-2x

2x-18 =42

Add 18 to each side

2x-18+18 = 42+18

2x= 60

Divide by 2

2x/2 = 60/2

x = 30

Step-by-step explanation:

Let :-

Given ratio :-

→ Sum of ratios = 4 + 3 + 5 = 12 .

According to Question :-

→ 3/12 × x = £21

→ x = £21 × 12/3

→ x = £ 84 .

Answer:

£84.

Step-by-step explanation:

There are 4 + 3 + 5 = 12 parts.

The second person got 3 parts so we can write:

3/12 x = 21      where x is the required amount of money

x = 21 * 12/3

= 21 * 4

= £84.

Answer:

10 cm

Step-by-step explanation:

From the diagram,

Applying,

lw = 5/2(bh)..................... Equation 1

Where l = length of the rectangle, w = width of the rectangle, b = base of the triangle, h = height of the triangle.

make w the subject of the equation

w = 5(bh)/2l............... Equation 2

From the diagram,

Given: l = 12 cm, b = 6 cm, h = 8 cm

Substitute into equation 2

w = 5(6×8)/(2×12)

w = 10 cm

Hence the width of the rectangle is 10 cm

Answer:

s = 25

Step-by-step explanation:

First we go from point (30, 50) to point (-10, 30).

Change in x: -10 - 30 = -40

Change in y: 30 - 50 = -20

Since a change in x of -40 results in a change in y of -20, we divide both changes by 4 to get:

a change of -10 in x results in a change of -5 in y.

Now we go from point (-10, 30) to point (-20, s).

The change in x is -20 - (-10) = -10

The corresponding chang ein y must be -5.

y = 30 - 5 = 25

Answer: s = 25

Answer:

Step-by-step explanation:

Area of dirt in the flower bed = area of flowerbed - area of 3 trapezoids

Area of flowerbed:

The flowerbed is in the shape of a parallelogram

The area of a parallelogram can be calculated by multiplying the base length times the height

Base length = 20ft

Height = 10ft

Area of flowerbed = 10 * 20 = 200ft^2

Area of rockbeds

The rockbeds are in the shape of trapezoids

The area of a trapezoid can be calculated using this formula

A = (a + b)/2 * h

Where a and b = bases and h = height

The rockbeds of base lengths of 2 and 4 and have heights of 3

So area of rockbeds = (4 + 2)/2 * 3

4 + 2 = 6

6 / 2 = 3

3 * 3 = 9

We then multiply that by 3 ( because there are three rockbeds )

9 * 3 = 27

Finally we subtract the areas

200 - 27 = 173

Answer:

B

Step-by-step explanation:

If you substitute in the value x = 1, and y = 4 (based on the point given), (2x)^2 is the only expression that makes it work.

Answer:

[see below]

Step-by-step explanation:

The bike's original price is 300 dollars. It has been discounted by 30%.

300 * 0.3 = 90

The price would be 90 dollars off.

300 - 90 = 210

$210 would be the subtotal.

There is also an 8% sales tax.

210 * 0.08 = 16.80

210 + 16.80 = 226.80

Hope this helps you!

Answer:

cost of the bike =$300

discount = 30%

Price of the bike ={ (30/100)×300}-300=210

Sales tax= 8%

Final cost =( 8/100)×210=16.80+210=226.80
