The length of the patio in the drawing is 2 centimeters.

A scale drawing is a smaller image in terms of dimensions of an original image / building / object. The scale drawing is usually reduced at a constant dimension

The length of the drawing = 20 / 10 = 2cm

The equation of the circle shown is:

[tex]x^2 + y^2 = 100[/tex]

The equation of a circle of center [tex](x_0, y_0)[/tex] and radius r is given by:

[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]

From the graph, it can be seen that the center of the circle is (0,0), thus [tex](x_0, y_0) = (0,0)[/tex] and the radius is of r = 10, hence the equation is:

[tex]x^2 + y^2 = 100[/tex]

Looking at the question, I'm assuming it has a mistake.

However, I will first attempt to solve it normally:

Simply combine like terms to get 5x = 180, and thus x = 36, and y = 72

The first mistake possibility is that the first equation should be 3x + 2y = 180

If that is the case, simply substitute in 2x for y, turning the equation into

3x + 2 (2x) = 180

3x + 4x = 180

7x = 180

Thus, x = 25.715 and y = 51.43

Another possible mistake is that the first equation should be 3y + 2x = 180

Solve similar to the first mistake

3 (2x) + 2x = 180

6x + 2x = 180

8x = 180

Thus, x = 22.5, and y = 45

Answer:

Larger number = 30
Smaller number = 8

Step-by-step explanation:

Let x = larger number

Let y = smaller number

x + y = 38 ————> (1)

x = y + 22 ————> (2)

Substitute for x using first equation

(y + 22) + y = 38

2y + 22 = 38

2y = 16

y = 8

Substitute for y using second equation

x = 8 + 22

x = 30

Answer:

x = 34

Step-by-step explanation:

5(x + 7) = 6x + 1

Distributive property

5x + 35 = 6x + 1

Subtract 5x from both sides

35 = x + 1

Subtract 1 from both sides

34 = x

Answer:

x = −21.25

Step-by-step explanation:

0.4(-0.2x - 3) = 0.5

distribute the .4

.4 * -0.2 = -0.08x and 0.4 * -3 = −1.2

we now have -0.08x - 1.2 = 0.5

next we add 1.2 to both sides

-0.08x - 1.2 + 1.2 ( these two 1.2's cancel out )  = 0.5 + 1.2 ( 0.5 + 1.2 = 1.7)

we then have -0.08x = 1.7

We then divide both sides by -0.08

-0.08/-0.08 = x

1.7 / -0.08 = −21.25

we're left with x = −21.25

Answer: 21.25

Answer:

9/12 = 4/x

Step-by-step explanation:

The height of the larger triangle is 9. The base of the larger triangle is 12. So let's make the ratio 9/12.

The height of the smaller triangle is 4. The base of the smaller triangle is x. So let's make the ratio 4/x.

Since both triangles are congruent, let's make these both equal each other to solve for x (if you need to).

Thus, it's 9/12 = 4/x.

The length and width of the terrace are 15 feet and 6 feet respectively.

The area of the terrace is 90 ft²

The scale of the plan is 2 inches : 6 feet.

Therefore, 2inches represents 6 feet.

According to the drawing;

Therefore,

The area can be found as follows:

where

l = length

w = width

Therefore,

area = 15 × 6 = 90 feet²

Answer:

Step-by-step explanation:

Let age of Jane = x

Mary's age = x + 1

Sum of both their ages = 15

x + x +1 = 15

2x + 1 = 15

Solution:

Subtract 1 from both sides

2x = 15- 1

2x = 14

Divide both sides by 2

x = 14/2

x = 7

Jane's age = 7

Mary's age = 8

Answer: The distance between 1 and 3 in the coordinate grid is 10 units right and 5 units up. distance between 6 and 15 is 6 units to the left and 9 units up.

Step-by-step explanation: I don't know if it's correct?

The distance between points (1, 3) and (6, 15) is 13 units.

The distance between two points is defined as the length of the line segment between two places representing their distance. Most significantly, segments that have the same length are referred to as congruent segments and the distance between two places is always positive.

The formula of the distance between two points is P(x₁, y₁) and Q(x₂, y₂) is given by: d (P, Q) = √ (x₂ – x₁)² + (y₂ – y₁) ².

To determine the distance between points  (1, 3) and (6, 15)

D = √( 6– 1)² + (15 – 3)².

D = √( 5)² + (12)².

D = √25 + 144.

D = √169.

D = 13

Hence, the distance between points (1, 3) and (6, 15) is 13 units.

Answer:

23 and 31

Step-by-step explanation:

substitute x = 2 into f(x) and x = 4 into g(x)

f(2) = 2(2) - 3 = 4 - 3 = 1

g(4) = 5(4) + 2 = 20 + 2 = 22

Then

f(2) + g(4) = 1 + 22 = 23

----------------------------------------------

substitute x = 8 into f(x) and x = 2 into g(x)

f(8) = 5(8) - 3 = 40 - 3 = 37

g(2) = 3(2) = 6

Then

f(8) - g(2) = 37 - 6 = 31
