Answer:

12a

Step-by-step explanation:

Because -9a and 9a would get rid of themselves the only "a-value" left is 12a. 10 and -10 also cancel each other out so 12a is all that is left.

Answer:

96 bales

Step-by-step explanation:

[tex]\frac{64}{4}[/tex] = [tex]\frac{x}{6}[/tex]

You must multiply 6 by 64, which is 384.

Then you divide that by 4, which is 96.

Therefore, the answer is 96.

Also, I lined up the bales in the same row and horses in the same row, so this way can help. It can also help if it's in the same column though, but I hope this helped you!

Answer:

3/x

Step-by-step explanation:

1 wall - x hours

y wall - 3 hours

y = (1*3)/x=3/x

The fraction of the wall that she paints in 3 hours is 3/x.

Here,

A painter paints a wall in x hours.

We have to find, the fraction of the wall that she paints in 3 hours.

What is fraction?

A fraction simply tells us how many parts of a whole we have.

Now,

Here, A painter paints a wall in x hours

1 wall = x hours

Let number of walls is z when she paints in 3 hours.

z wall = 3 hours

Hence, The fraction of the wall that she paints in 3 hours =( 1 x 3)/x

                                                                                        = 3/x

[tex]\bold{\dfrac{1}{12}}[/tex]

Step-by-step explanation:

The dice is rolled 3 times.

To find:

The probability that a 4 will come up exactly twice = ?

Solution:

Let 4 comes up exactly twice, let the third number be [tex]x[/tex].

The possible outcomes can be:

([tex]x[/tex], 4, 4) where [tex]x[/tex] can be any number between 1 to 6 , so 6 outcomes.

(4, [tex]x[/tex], 4) where [tex]x[/tex] can be any number between 1 to 6 , so 6 outcomes.

(4, 4, [tex]x[/tex]) where [tex]x[/tex] can be any number between 1 to 6 , so 6 outcomes.

So, the total number of favorable outcomes possible = 6 + 6 + 6 = 18

Total number of outcomes that can be possible at roll of 3 dice:

6 [tex]\times[/tex] 6 [tex]\times[/tex] 6  = 216

Formula for probability of an event E is given as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

[tex]P(\text{exact 2 fours}) = \dfrac{18}{216}\\\Rightarrow \bold{P(\text{exact 2 fours}) = \dfrac{1}{12}}[/tex]

Answer:

[tex]2.3x+1.4=8.5[/tex], width = 3.087 feet.

Step-by-step explanation:

Let as consider width of the door be x feet.

It is given that height of a door is 1.4 feet more than 2.3 times its width. So,

[tex]Height=2.3x+1.4[/tex]

The height of the door is 8.5 feet.

[tex]2.3x+1.4=8.5[/tex]

Therefore, the required equation is [tex]2.3x+1.4=8.5[/tex].

[tex]2.3x=8.5-1.4[/tex]

[tex]2.3x=7.1[/tex]

[tex]x=\dfrac{7.1}{2.3}[/tex]

[tex]x\approx 3.087[/tex]

So, the width of the door is about 3.087 feet.

Answer:

Hsu makes $35,950.50 and Alkena makes $48,418.50

Step-by-step explanation:

Create a system of equations, where h is the amount Hsu makes and a is the amount Alkena makes:

a + h = 84,369

a = h + 12,468

Solve by substitution by plugging in h + 12,468 as a:

h + 12,468 + h =  84,369

2h + 12,468 = 84,369

2h = 71,901

h = 35,950.50

Plug this into the equation, a = h + 12,468 , to solve for a

a = 35,950.50 + 12,468

a = 48,418.50

So, Hsu makes $35,950.50 and Alkena makes $48,418.50

If x and y may be any real number, there is no minimum value for C. It can approach negative infinity.

If C is a constant, and the domain of x is all real numbers, there is no minimum for y. It can approach negative infinity.

We're not sure what you want or what restrictions may exist. The given relation does not suggest any minimum. We'd have to say it Does Not Exist.

- A reflection can be done on a point, shape, or object

- A reflection flips a shape across a line

Step-by-step explanation:

A reflection is a rigid transformation, meaning that the object that you are reflecting does NOT change size or shape. A reflection is when you graphically "flip" an image across a line such as the x-axis or the y-axis.

Answer:

The Expression is equivalent to 12+3+ negative 7

Step-by-step explanation:

When you sub tract something for example 5-3 the three can be looked at as a negative number. 5-3=2 but 5+ (-3)=2 as well

The associative property indicates that the true statement about the expression is the option;

''The expression is equivalent to 12 + 3 + (negative 7) because of the associative property''

The associative property is related to the grouping of the numbers in an operation. According to the associative property changing the grouping of numbers does not change the result of addition and multiplication.

The associative property allows us to change the grouping of the addition operation, so we can rewrite the expression as follows; (12 + 3) + (negative 7), which simplifies to 15 + (negative 7) or 8. The commutative property on the hand, allows us to change the order of the addition operation. However, with regard to the question, it is not relevant because the expression involves addition and subtraction

Tip amount: $6.49

Final amount of the bill: $38.92

Step-by-step explanation:

We need to calculate the tip amount which is 20% of $32.43.

Then we will add the tip amount to $32.43.

To find a percent of a number, change the percent to a decimal by dividing the percent by 100 and multiply by the number.

20% of $32.43 =

= 0.2 * $32.43

= $6.486

We round off the tip amount to the nearest cent, $6.49

The tip amount is $6.49

To find the final amount of the bill, we add the tip amount to the bill amount.

$32.43 + $6.49 = $38.92

Answer:

18

Step-by-step explanation:

First, I'm assuming AB=4=4x-2 was a typo and it's supposed to be AB = 4x - 2

AB=BC

AB = 4x - 2 BC = 3x + 3

4x - 2 = 3x + 3

Solve for x Add 2 to each side

4x - 2 = 3x + 3

4x - 2 + 2 = 3x + 3 + 2

4x = 3x + 5 Subtract 3x from each side.

4x - 3x = 3x- 3x + 5

4x - 3x = 5

x = 5

Now plug back in to the original equations

AB = 4x - 2                  BC = 3x + 3

AB = 4 (5) - 2               BC = 3(5) + 3

AB = 20 - 2                  BC = 15 + 3

AB = 18                        BC = 18

So AB is 18

Step-by-step explanation:

The odd function from the following function is f(x) = 6x³ + 2x.

The function f(x) is said to be an odd function if the output value of f(-x) is the same as the negative of f(x) for all values of x in the domain of f.

f(-x) = -f(x)

The functions are given below.

f(x) = 3x² + x

f(x) = 4x³ + 7

f(x) = 5x² + 9

f(x) = 6x³ + 2x

f(x) = 3(-x)² + (-x) = 3x² - x

f(x) = 4(-x)³ + 7 = -4x³ + 7

f(x) = 5(-x)² + 9 = 5x² + 9

f(x) = 6(-x)³ + 2(-x) = -6x³ - 2x = - (6x³ + 2x)

= -1

B2 + B1 / 2

= (-6+(-2)) / 2

= -8 / 2

= -4

therefore, (-1,-4) is your midpoint.
