Answer:

The value of the x variable is 30.

Step-by-step explanation:

Since the triangles are similar, the corresponding sides of both triangles have a common ratio. The 18:12 ratio of side LK and QR is equal to 2:3, and the 21:14 ratio of sides JL and PQ is also equal to 2:3. Based on this, we know that 2/3 * x = 20, so we isolate the x variable by dividing both sides of the equation by 2/3 to get the answer: x = 30.

Answer:

I think it's 7x7 - 2x-4 + 3

Answer:

21 and 34

Step-by-step explanation:

This is a Fibonacci sequence. Basically, the next term is the sum of the 2 previous terms.

Notice the third term, it's the sum of 2 and 1.

Notice the fourth term, it's the sum of 3 and 2.

Each term follows the same pattern.

Hey there!

• Mean is the average (total) with the given set of numbers in your data plot

• Average is the sum of your total numbers that are divided by the total numbers in your data plot.

technically they're all divisible by said digit but when you put 6 it's the only one with a product of a whole number. hope this helps.

Answer:

x = 62

Step-by-step explanation:

The triangle is isosceles. That means two sides are equal. The angles opposite those equal sides are also equal.

Every triangle has 180 degrees.

The unmarked angle is also x.

x + x + 56 = 180             Combine the left

2x + 56 = 180                 Subtract 56 from both sides

2x = 180 - 56

2x = 124                         Divide by 2

2x/2 = 124/2

x = 62

Answer:

An ordinary angle is a measure of the length subtended by a one-dimensional subset of the plane. For example, an angle of 60∘ is subtended from a point by a 16 portion of a circle centered at that point. The 16 arc that subtends the angle is a one-dimensional subset of the two-dimensional plane.

Answer:

y = -3x + 2

Step-by-step explanation:

We will use the form y = mx + b

m is the slope

b is the y intercept

y = -3x +2

Answer:

Step-by-step explanation:

The slope is calculated using rise over run, or y2-x2/y1-x1

The clear coordinates are (-3, 2) and (1,4).

Let 4 be y2, 1 be x2, 2 be y1 and -3 be x1.

4-1/2--3 (2+3)

the slope is 3/5

Step-by-step explanation:In this section, we study how the graphs of functions change, ... 3. 4. 5 y = f(x). The Fundamental Graphing Principle for Functions says that for a point ...If the graph is transformed into the graph defined by y= f(2x–8), determine the domain of the transformed graph. y = f[2(x-4)} horizontal stretch by shift 4 ...

Following are the calculation to the method value:

Solution:

[tex]\to \cos (xy) = y-1\\\\\to \frac{d}{x} \ (\cos xy) = \frac{d}{dx}\ (y-1)\\\\\to -\ ( \sin xy) \frac{d}{dx} \ (xy) = \frac{dy}{dx}\\\\\to -\ ( \sin xy) ( x\ \frac{d}{dx} + y) = \frac{dy}{dx}\\\\\to - x \sin (xy) \ \frac{dy}{dx} -y\sin (xy) =\frac{dy}{dx}\\\\\to \frac{dy}{dx} (1+ x \sin \ xy) = - y \sin xy\\\\\to \frac{dy}{dx}=\frac{-y \sin xy}{1+x\sin xy }\\\\[/tex]

When [tex]\ x=\frac{\pi }{2} \ \ \ and \ \ \ y=1\\\\[/tex]

Answer:

1.3 < x < 37.7

Step-by-step explanation:

Given 2 sides of a triangle then the 3rd side x is in the interval

difference of 2 sides < x < sum of 2 sides , that is

19.5 - 18.2 < x < 19.5 + 18.2 , then

1.3 < x < 37.7

Answer: the first number is 9, the second is 4

Step-by-step explanation:

let n = 1st number

let n-5 = 2nd number

n+(n-5)=13

collect like terms: 2n-5=13

add 5 to both sides

2n=18

divide both sides by 2

n=9

n-5=4

Step-by-step explanation:

So the answer is that 19 7/10 as a decimal is 19.7.

Answer:

Step-by-step explanation:

We can form an equation from the two given points.

The standard form of an equation for a straight line is y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).

We can calculate the slope from the two given points, (10,0) and (0,-15). Slope is Rise/Run, where Rise is the change in y and Run is the change in x.

From the two given points, starting at (0,-15) and ending at (10,0):

Rise = (0-(-15)) = +15

Run = (10-0) = 10

Rise/Run (slope) = 15/10 or 1.5

The equation becomes y = (1.5)x + b

We know b, since it is the value of y when x=0. The point (0,-15) says -15 when x=0. You can also can find b by entering either of the two given points and solving for b. I'll pick (10,0):

y = (1.5)x + b

(0) = (1.5)*(10) + b

0 = 15 + b

b = -15

The equation is y = (1.5)x - 15

Answer:

$600

Step-by-step explanation:

1 week = $20

30 weeks = 20 x 30 = $ 600

The saving of 30 weeks would be an amount of 600 dollars.

In mathematics, Multiplication operations perform Multiplying values on either side of the operator.

For example 4×2 = 8

George makes $20 doing lawn work for 4 hours each week.

He has been saving this money for 30 weeks

The saving of one week = $20

The saving of 30 weeks = $20 × 30

Apply the multiplication operation to get

The saving of 30 weeks = $600

Alternative method :

According to the given situation, we can write a ratio as

one week : 20 dollars = 30 weeks : x dollars

⇒ 1 / 20 = 30 / x

Apply the cross-multiplication operation,

⇒ 1 × x = 30 × 20

Apply the multiplication operation to get

⇒ x = 600

Hence, the saving of 30 weeks would be an amount of 600 dollars.

Answer:

4

Step-by-step explanation:

So, since we already know x = 1, we just need to figure out what 3 x 1 is. (Since there's no space between the 3 and the x, 3x would be 3 times x.)

3 x 1 = 3.

So, our "new equation" is:

1 + 3

Add them together to find the answer:

1 + 3 = 4

4 is your answer.
