The unknown number will be 5 if we add two to twice a number, the result is twelve.

Let the unknown number be x.

Then the twice of the known number be 2x.

According to the given question.

If we add two to twice a unknown number, the result is twelve.

So, from the given scenario we can say that

2 + 2x = 12

Now we have a linear equation in one variable 2 + 2x = 12 and we have to solve it for x which gives us the unknown number.

Therefore,

2 + 2x = 12

⇒ 2x = 12 - 2   (subtracting 2 from both the sides)

⇒ 2x = 10

⇒ x = 10/2

⇒ x = 5

Hence, the unknown number will be 5 if we add two to twice a number, the result is twelve.

Answer:

Step-by-step explanation:

-12 = 4(-6 + f)

-12 = (-6 * 4 + f * 4)

-12 = (-24 + 4f)

-12 = -24 + 4f

Solving for variable 'f'.

Move all terms containing f to the left, all other terms to the right.

Add '-4f' to each side of the equation.

-12 + -4f = -24 + 4f + -4f

Combine like terms: 4f + -4f = 0

-12 + -4f = -24 + 0

-12 + -4f = -24

Add '12' to each side of the equation.

-12 + 12 + -4f = -24 + 12

Combine like terms: -12 + 12 = 0

0 + -4f = -24 + 12

-4f = -24 + 12

Combine like terms: -24 + 12 = -12

-4f = -12

Divide each side by '-4'.

f = 3

Simplifying

f = 3

The required amount to be held this week for federal tax is $12.75.
               

Here,
Last week's earnings = $240
Difference with marked amount = $240 - $195 = $45
This comes under type 2
So tax = 14 + 15% of 45
   tax = 14.40 + 6.75
   tax = $21.15

This week's earnings = $325
The difference with marked amount = $325 - $195 = 130
Tax = 14 + 15% of 130
Tax = 14.40 + 19.5
Tax = 33.9
the amount held this week = 33.9 - 21.15
                                         = $12.75

Thus, the required amount to be held this week for federal tax is $12.75.

Using the Pythagorean Theorem, the length of CD, to the nearest hundredth, is: 11.62.

The measure of the longest side of a right triangle when squared will be equal to the sum of the squares of the other smaller sides of the right triangle.

Given the following:

Side AB = 6

Side AC = 12

Based on the perpendicular bisector theorem, AD = 1/2(AB) = 1/2(6) = 3.

Using the Pythagorean theorem, we have:

Length of CD = √(AC² - AD²)

Length of CD = √(12² - 3²)

Length of CD = √(144 - 9)

Length of CD = 11.62

Thus, using the Pythagorean Theorem, the length of CD, to the nearest hundredth, is: 11.62.

The probability of getting a green marble and rolling an even number is

4/29.

A compound event is one that includes more than one sample point.

For the given question, we must multiply the probability of selecting a green marble and going to roll an even number.

The total marbles contained in the jar are;

The formula for probability is;

P(event) = favourable outcome/total outcome

There are six sides to a die/number cube. Each has a 1/6 chance of happening.

There are three even numbers in this situation. The probability of an even number is:

P(even) = 3/6 = 1/2

The probability of selecting the green marble;

P (green marble) = 8/29

We must now determine the likelihood of both events occurring. So multiply both  probabilities to get the following answer:

8/29 × 1/2 = 4/29

The probability of selecting a green marble as well as rolling an even number are 4/29.

Answer: 1

Step-by-step explanation:

The ones place is the place furthest to the right before the decimal. In this case, the decimal is implied because 431 is a whole number. 431 can also be written as 431.0 which more clearly shows this.

The ones place contains the value 1.

In case you need it later,

The tens place is 3 and the hundreds place is 4.

The equation that is shown by the graph is y = -x + 4

From the graph, we have the following observation:

The above means that the graph represents a linear equation

The points on the graph are

(0, 4) and (4, 0)

Calculate the slope using

m = (y2 - y1)/(x2 - x1)

This gives

m = (0 - 4)/(4 - 0)

Evaluate

m = -1

The linear equation is represented as

y = mx + c

So, we have

y = -x + c

Where c = y, when x = 0

So, we have:

c = 4

This means that

y = -x + 4

Hence, the equation that is shown by the graph is y = -x + 4

Answer:

the two prime factors is (113) (97)

Step-by-step explanation:

The computation of the two prime factors is  is shown below:

The given expression is

105^2 - 8^2

Here we used the formula i.e.

a^2 - b^2 = (a + b) (a - b)

where,

a = 105

b = 8

Now

= (105 + 8) (105 - 8)

= (113) (97)
