Answer:

scientific notation = 2.226 * 10^8

Standard form = 222600000

As it is 22.26 * 10^7

Step-by-step explanation:

(5.3x10^4)(4.2x10^3)

Since all the numbers are being multiplied by each other, one can use the associative property to change the order in which they are multiplied.

5.3 x 10^4 x 4.2 x 10^3

= 5.3 * 4.2 * 10^4 * 10^3

= 22.26 * 10^7

Either convert back to scientific notation, standard form or keep as it is.

scientific notation = 2.226 * 10^8

Standard form = 222600000

As it is 22.26 * 10^7

Answer:

(x,y)=(-1,-4)

Step-by-step explanation:

-4x + y = 0

+4x         +4x

y=4x

-5x - 2y = 13

+5x          +5x

-2y = 5x+13

-2(4x) = 5x+13

-8x=5x+13

-5x -5x

-13x/-13=13/-13

x=-1

Thus:

y=4x

y=4(-1)

y=-4

Answer:57/100

Step-by-step explanation:

First, convert 3/10 into hundreths to get a denominator equal to the other:

3/10 km = 30/100km

Add the numerators: 27+30=57

Place numerator over common denominator: 57/100

y = x + 8

Subtract 8 from both sides

y - 8 = x

Answer:

x= y-8

The answer would be -7/12

Step-by-step explanation:

What you would do is

a/b×c/d=ac/bd

this would be the formula

so what you would do is -7 (which is the numerator X the other numerator which equals -7 times 1= -7

then you would do 2 X6= which is 12 so the answer would be 7/12 because you can't simplify it anymore

Answer:

67/24

Step-by-step explanation:

Remember PEMDAS

First you solve the parenthesis which is 11/12.

Then do exponents 2^4=16

For division do left to right so 2/3 ÷ 16 = 1/24

and the other division is 11/12 ÷ 1/3 = 11/4

Add the two 1/24 + 11/4 = 67/24

67/24 is the answer

Answer:

[tex]a=\frac{K}{4+9b}[/tex]

Step-by-step explanation:

[tex]K=4a+9ab[/tex]

Switch sides:

[tex]4a+9ab=K[/tex]

Factor out a:

[tex]a\left(4+9b\right)=K[/tex]

Divide both sides by: [tex](4+9b)[/tex]

[tex]\frac{a\left(4+9b\right)}{4+9b}=\frac{K}{4+9b}[/tex]

[tex]a=\frac{K}{4+9b}[/tex]

Answer:

Step-by-step explanation:

1. 13x + 2 = 4x + 38

   9x + 2 = 38

    9x = 36

     x = 4

2. 6(2/3 + q/6 = 5/6q + 1/3)

      4 + q = 5q + 2

    4 - 4q = 2

     -4q = -2

       q = 2/4= 1/2

3. 6n + 24 = -18

    6n = -42

     n = -7

4. -11 + 3b + 15 = 7

   3b + 4 = 7

    3b = 3

    b = 1

5. 5 + 2n + 2 = 2n

   2n + 7 = 2n

   0 ≠ 7

6. 7 - 3r = r - 8  - 4r

  7 -3r = -3r - 8

  0 ≠ -15

7. 14v + 6 = 10 + 14v - 4

  14v + 6 = 14v + 6

  0 = 0

  infinitely many solutions

8. 5h - 7 = 5h - 10 + 3

   5h - 7 = 5h - 7

    0 = 0

   infinitely many solutions

9. a. 10x + 10 (triangle)

    b. 4x + 2x + 26 = 6x + 26 (rectangle)

      10x + 10 = 6x + 26

     4x + 10 = 26

     4x = 16

      x = 4

The answer is D.

Turning fractions into decimals will help you eliminate answers!!

How I got D:

-2 3/4 can be turned into -2.75 by dividing 3/4.

-2 3/4 is the smallest number out of all of them so it has to be first.

-2.67 is the second smallest value.

3/5 is .60 making it the third smallest value.

4 is the second largest value.

17/4 is 4.25, which is the largest.

A is not correct because -3/5 is not the smallest number.

B Is not correct because the largest number is 17/4.

C is not correct because -2.67 is not the smallest number.

The angle "b" and the angle "d" are both the same angle measure. In other words, they are opposite angles that share the black dot in the middle. Angle "a" and angle "c" are both opposite angles which make them the same. They can also be called congruent angles. Even if they are facing a different direction, they are the same.

Therefore, the answer is 130 degrees

Best of Luck!

answer:

130 degrees

explanation:

the angles "a" & "c" are opposite (also called congruent) so they are the same.

[tex]B=\frac{h+D^{2}5g}{D^{2} }[/tex]

h = D²(B - 5g)

h = D²B - D²5g

h + D²5g = D²B

B = (h + D²5g)/D²

Step-by-step explanation:

If two lines have the same slope and the same y-intercept, there are infinite solutions.

If two lines have the same slope and different y-intercepts, there are zero solutions.

Otherwise, if the two lines have different slopes, then there is one solution.

The slope of the first line is 3/8.  The slope of the second line is 16/32 = 1/2.  The slopes are different, so there is only one solution.

The solution of the given system of equations is (x, y) = (8.75, 2).

Given: System of equations

3x - 8y = 10                           …(1)

16x - 32y = 75                       …(2)

Consider equation (2).

⇒ 16x - 32y = 75

Dividing both sides by 16, we get:

⇒ x - 2y = 75/16

⇒ x = 2y + 75/16                  …(3)

Now, substitute the value of x = 2y + 75/16 in equation (1), we get:

⇒ 3(2y + 75/16) - 8y = 10

⇒ 6y + 225/16 - 8y = 10

⇒ 2y = 225/16 - 10

⇒ 2y = (225 - 160)/16

⇒ 2y = 65/16

⇒ y = 65/32

⇒ y ≈ 2

Now, put the value of y = 65/32 in equation (3), we get:

⇒ x = 2(65/32) + 75/16

⇒ x = (65/16) + (75/16)

⇒ x = 140/16

⇒ x = 8.75

Therefore, the solution for the given simultaneous equation is;

(x, y) = (8.75, 2)
