Answer:

The similarities are

1) Both diagrams consists of an horizontal line l for the upper diagram and k for the lower diagram

2) Both diagrams have a vertical plane Z for the upper diagram and A for the lower diagram

3) Both diagrams have rays, which are C for the upper diagram and G and H for the lower diagram

The differences are

1) The upper diagram has only one plane, while the lower diagram has two planes, seemingly rotated at an angle of about 90° to each other

2) The upper diagram has only one line, l, while the lower diagram has two lines, l and GH

Answer:

x = 6

One-fourth x + one-half = one-third x

Step-by-step explanation:

1/4 x + 1/2 = 1/3 x

1/4 x - 1/3 x = - 1/2

(3x - 4x)/12 = -1/2

-x/12 = -1/2

-x = -12/2

-x = -6

x = 6

Answer:

Mark owes Kira $2.

Step-by-step explanation:

The correct answer is “Mark owes Kira $2” because first Kira owes $5 to the Mark and then Mark gives $7 to Kira. Here it can be seen that Mark is giving $2 extra and $5 is the amount which he is refunding. So the net amount $2 that the Mark gives to Kira. Therefore, the statement “Mark owes Kira $2” is justified and correct.

Answer:

1.0346 x [tex]10^{22}[/tex]

Since the exponent of the scientific notation is positive, move the decimal point  22  places to the right.

10,346,000,000,000,000,000,000

The standard notation will be 10346000000000000000000.

It is given that total distance from earth to sun is 1.0346 × [tex]10^{22}[/tex]miles.

What will be the standard notation for this ?

What do you mean by the standard notation of a number ?

Standard notation of a number is when a number is written with only number digits i.e., the standard notation for 2 × [tex]10^{2}[/tex] will be 200.

The total distance from earth to the sun would be written as ;

1.0346 x [tex]10^{22}[/tex] miles.

We need to put the decimal point 22 places right ;

So , It can be written as ;

10346000000000000000000

Thus , standard notation will be 10346000000000000000000.

Answer:

You have the correct answer

y = -3x + 6

Step-by-step explanation:

to see if you chose the correct equation just substitute the x value in for x and solve the equation to see if you get the correct y value

ex:

-2 , 12

y = -3x + 6

y = -3 (-2) + 6

y = 6 + 6

y = 12

Answer:

$1,257.63

Step-by-step explanation:

A= p(1+r/n)^nt

P = principal = $847

r= interest rate = 2.2%

n= 360 per year

t= 18 years

A= p(1+r/n)^nt

= 847(1+0.022/360)^360*18

= 847(1+0.000061)^6,480

= 847(1.000061)^6,480

=847(1.4848)

= $1,257.63

Total balance in 18 years = $1,257.63

Answer:

A

Step-by-step explanation:

So we have the equation:

[tex]-8x+4=36[/tex]

Subtract 4 from both sides:

[tex]-8x=32[/tex]

Divide both sides by -8:

[tex]x=-4[/tex]

And we're done!

The answer is A

Answer:

A. x = -4

Step-by-step explanation:

We are given the equation:

-8x+4=36

We want to solve for x. Therefore, we must isolate x on one side of the equation.

4 is being added to -8x. The inverse of addition is subtraction. Subtract 4 from both sides of the equation.

-8x+4-4=36-4

-8x=36-4

-8x=32

x is being multiplied by -8. The inverse of multiplication is division. Divide both sides of the equation by -8.

-8x/-8=32/-8

x= 32/-8

x=-4

Let’s check our solution. Plug -4 in for x and solve.

-8x+4=36

-8(-4)+4=36

32+4=36

36=36

This checks out, so we know our solution is correct.

The solution to the equation is A. x=-4

Answer:

PMN = 74°

Step-by-step explanation:

1. 6x + 5 + 4x + 18 = 163°

2. Combine like terms

3. 10x + 23 = 163°

4. Subtract 23 from both sides.

5. 10x = 140°

6. Divide 10 from both sides.

7. x = 14°

8. Now substitute the x in the equation for PMN with 14.

9. 4(14) + 18

10. Simplify

11. 56 + 18

12. Answer: 74°

Answer:

Answer:

[tex]\large\boxed{23}[/tex]

Step-by-step explanation:

Six times a number is decreased by fourteen, the result is 124.

Write an equation that represents this

(6 * x) - 14 = 124

Multiply 6 by x to remove the parenthesis

6x - 14 = 124

Add 14 to both sides of the equation

6x = 138

Divide both sides of the equation by 6

x = 23

The unknown number is [tex]\large\boxed{23}[/tex]

Hope this helps :)

Answer:

138
