please help me with this and explain your answer

Work Shown:

x = 0.212121...

100x = 21.212121....

Subtract the equations straight down. This means we subtract the left hand sides together, and the right hand sides are handled separately.

After those sets of subtractions, we are left with 99x = 21.

This solves to x = 21/99 when dividing both sides by 99 to isolate x.

Therefore, 21/99 = 0.212121...

Hi,

Answer is $0.19

Step-by-step explanation:-

We know that:-

15 dimes = $1.50

20 nickels = $1.00

8 quarters = $2.00

half dollar = $0.50

19 pennies = $0.19

Total = $5.19

Since Billy spended $5, so,

$5.19 - $5 = $0.19

Hope it helps you...

hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

Answer:

no we cannot add them, though we can multiply or divide them. You cannot add them because they have different variables, we need the same variables to add or subtract those.

Answer:

m = 65

Step-by-step explanation:

Given

- 13 = [tex]\frac{m}{-5}[/tex] ( multiply both sides by - 5 )

65 = m

Step-by-step explanation:

3p²-7p-6

Now, 9-2=7 and 9×2=18

3p²-9p+2p-6

By taking out common, we get

3p(p-3)+2(p-3)

(3p+2)(p-3)

Answer:

(3p + 2)(p - 3)

Step-by-step explanation:

[tex]3p^2-7p-6\\(3p+2)(p-3)[/tex]

Answer:

Hi! I'm happy to help.

A rational number is a number that repeats, or stops.

First of all, 8/5, in fraction and decimal form (1.6), stops, So it is Rational.

Next, we have pi. This number, doesn't ever stop, or repeat. ( 3.1415926535 897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679...) So, pi, is Irrational.

Next, we have 0. This number stops, so it is Rational.

Next, we have[tex]\sqrt{1}[/tex], the square root of 1, is 1, because 1 squared is one. 1 stops, so it is Rational.

Next, we have 4.46466... This number doesn't stop, and it doesn't seem to repeat, so it is Irrational.

Next, we have -6. -6 stops, so it is Rational.

Finally, we have [tex]\sqrt{2}[/tex]. The square root of 2 is 1.41421356237...

This number doesn't stop, and doesn't repeat, so it is Irrational.

To sum it up: Number 1, 3, 4, and 6 are Rational, and Number 2, 5, and 7 are Irrational.

I hope this was helpful, keep learning! :D

Answer:

y= -6/5x +3

Step-by-step explanation:

y = mx + b is the formula for every linear equation. m is the slope (comment if you don't know how to find the slope), and b is the y-intercept. You just have to find those terms and plug them in.

Here is the proof

Answer:

35 Degrees

Step-by-step explanation:

Angle JKL is reffering to the whole angle. The angle is split into two, it gives us the measurement for angle 1 which is 38 degrees. To find the answer we simply subtract angle m from angle JKL. 73-38 = 35... So angle 2 is 35 degrees.

Integers.

The integers are the whole numbers, their opposites, and 0 . From the given numbers, −7 and 8 are integers. Also, notice that 64 is the square of 8 so −√64=−8 . So the integers are −7,8,−√64 − 7 , 8 , − 64 .

Answer:

3x - 13

Step-by-step explanation:

The perimeter is just the distance around the triangle. We have all three sides, so we can just add them together to get the total distance.

(x-6) + (x+2) + (x-9)

Group:

x + x + x - 6 + 2 - 9

3x - 13

Answer:

x = 21

Step-by-step explanation:

72+46+(2x+20)=180

118+20+2x=180

138+2x=180

138-138+2x=180-138

2x=42

2x/2=42/2

x=21

Answer:

6 cm

Step-by-step explanation:

Let each side of the equilateral triangle be a.

Given, area of an equilateral triangle = 9√3 cm2

Area of an equilateral triangle = (√3)/4 × (Side)²

=> (√3)/4 × a² = 9√3

[tex] {a}^{2} = \frac{9 \sqrt{3} }{ \frac{ \sqrt{3} }{4} } = \frac{9 \sqrt{3} }{ \sqrt{3} } \times 4 = 9 \times 4[/tex]

=> a² = 36

[tex] \sqrt{ {a}^{2} } = \sqrt{36} \\ a = (+ - )6[/tex]

∴ Side = 6 cm  [taking positive square root because side is always positive]

Answer:

y = 3x - 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{1}{3}[/tex] x - 4 ← is in slope- intercept form

with slope m = - [tex]\frac{1}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{3} }[/tex] = 3 , then

y = 3x + c ← is the partial equation

To find c substitute (3, - 1 ) into the partial equation

- 1 = 9 + c ⇒ c = - 1 - 9 = - 10

y = 3x - 10 ← equation of perpendicular line

Answer:

70 pi cm

219.80 cm

219.9114858 cm

Step-by-step explanation:

The circumference of a circle is given by

C = pi*d

C = pi * 70cm

Using 3.14 for pi

C = 219.80cm

Using the pi button

219.9114858cm

Circumference of circle = 2πr

Hence , r is 35 cm

⇛Circumference of circle = 2πr

⇛Circumference of circle = 2*3.14*35

⇛Circumference of circle = 6.28*35

⇛Circumference of circle = 219.8 cm

Hence , Circumference of circle is 219.8 cm

Answer:

I think the two digit number formed would be
