which of these is a composite number? 4 2 6 8

Answer:

b = 1

Step-by-step explanation:

8 = b - 1 + 8b

combine like terms

8 = 9b - 1

add 1 to both sides of the equation

8 + 1 = 9b - 1 + 1

8 + 1 = 9b

9 = 9b

divide both sides of the equation by 9

9/9 = 9b/9

1 = b

Answer:

b = 1

Step-by-step explanation:

Given

8 = b - 1 + 8b, that is

8 = 9b - 1 ( add 1 to both sides )

9 = 9b ( divide both sides by 9 )

1 = b

Answer:

x=4

Step-by-step explanation:

It's a parallel line so the equation is

100+19x+4=180

19x=180-100-4

19x=76

x=76/19

x=4

Answer: x = 4

Step-by-step explanation: The 2 angles are same-side interior angles, which are supplementary, and supplementary angles add up to 180, so we know that 19x + 4 = 80.

- 4. -4

19x = 76

/19. /19

X = 4

Answer:

12x - 15

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Given the inequality, y > -½, the graph that represents this would have a directed line starting from -½ and pointing to your right. It would also have an unshaded circle, or empty circle, signifying that -½ is not included among the set of possible values of y.

Thus, the right graph would be graph A.

Answer:

Albert by 5 more miles

Step-by-step explanation:

Tom:  50 * 2.5 = 125 miles

Albert:  65 * 2 = 130 miles

Albert drove for more miles

130-125 = 5 miles

Albert drove for 5 more miles

Answer:

More than 7

Step-by-step explanation:

Given that:

Joshua's goal is to sell more than 20 items at a farmer's market.

Number of items already sold = 6

So, number of more items to be sold > Total number of items to be sold - Number of items already sold > 20 - 6 > 14

Given that each customer buys 2 items.

Let [tex]c[/tex] be the number of customers.

So, number of items bought be the customers = Number of items bought by each customer multiplied by the number of customers = [tex]2c[/tex]

And as per the question statement,

Number of more items to be sold > 14 (as calculated in above step)

[tex]2c>14\\\Rightarrow \bold{c>7}[/tex]

Therefore, the answer is: More than 7 additional customers are required.

Answer:

Step-by-step explanation:

Hi!

We will find the monthly budget using proportions, like this:

15% = 0,15___________600$

100% = 1_____________x$

__________________________

x = (600*1)/0,15

x = 600/0,15

x = 4000

Their monthly budget is 4000$.

Hope this helps!

Answer:

189 cm²

Step-by-step explanation:

The area (A) of a rhombus is calculated as

A = [tex]\frac{1}{2}[/tex] × product of diagonals

   = [tex]\frac{1}{2}[/tex] × 18 × 21 = 9 × 21 = 189 cm²

Answer:

Lol I hope she didn't hit you yet. The answer is x=14 :)

Step-by-step explanation:

So the first thing that you would want to do is find what 9 is multiplied by to get 21. To do this, we can just do a simple algebraic equation: 9x=21. The answer is 7/3 because mAgIc. So now, we can also multiply 6 by 7/3. this would be 42/3 because of more MaGiC. 42/3 divides into 14 because im  just obviously a mage. lol I hope this helped.

Answer:

25 grams

Step-by-step explanation:

Pennies made after 1984 weigh 2.5 grams. How much would 10 pennies weigh?

From the above question:

1 penny = 2.5 grams

10 pennies = x grams

Cross Multiply

1 × x grams = 10 pennies × 2.5 grams

x grams = 25 grams.

Hence, the weight of 10 pennies is 25 grams

Answer:

0.151

Step-by-step explanation:

1.51=c10

we divide 10 by both sides

1.51/10 = c10/10

we cancel 10/10 and 1.51/10=0.151

so

c=0.151

Answer:

x = 48°

Step-by-step explanation:

x + x + 84° = 180°

2x = 180° - 84°

2x = 96°

x = 96°/2

x = 48°

Answer:

84+2a=180

2a=180-84

= 96

2a=96/2

=48

So, each angles are 48 degrees.

Answer:

20

Step-by-step explanation:

Answer:

Sorry no idea

Step-by-step explanation:

Answer:

x = 9.

Step-by-step explanation:

If you meant (x + 13) = 24, then we first must subtract 24 by 13.

24 - 13 = 9

Now, check your work by replacing the "x" with 9.

(9+ 13) = 24

24 = 24 <----- This is a true statement.

Therefore, x = 9.

Hope this helps! :D

Answer:

( 9, -35 )

Step-by-step explanation:

We can figure out how far the midpoint is from point A and just add the same values to the midpoint's coordinates to get the location of point B.

From A to Midpoint in the X direction:

+ 6

From A to Midpoint in the Y direction:

-15

The coordinate of the midpoint is:

( 3, -20)

3 + 6 = 9

-15 + (-20) = -35

The coordinates of B are:

( 9, -35 )
