Solve for the following equation for “f”

Answer:

Step-by-step explanation:

Let Colin - x, Dan - y, David - z.

We have:

Substitute and solve for z:

Now find x and y:

Answer:

£12

Step-by-step explanation:

Let the David's money be x

If David gets = x

Dan will get = 3x

Colin gets = 3x x 2

= 6x

So, the total money can be write as

[tex]x + 3x + 6x = 10x[/tex]

So, now let's find the amount of money which David have

[tex]10x = 20 \\ \frac{10x}{10} = \frac{20}{10} \\ x = 2[/tex]

So, David will get £2

And now let's find the amount of money which Colin will get

[tex]6x = 6 \times 2 \\ = 12[/tex]

He will get £12

Hope this helps you.

Company B is likely to get an offer of $43,000 or more.

Here we will use a normal distribution and calculation to calculate z-score for each company.

z-score for the company A = (43,000 - 41,000) / 1000

                                             = 2000/1000= 2

z-score for the company B = (43,000 - 41,000) / 5000

                                             = 2000/5000

                                             0.4

Now we will consult z-tables for Probability(P)

P(x > 43000 ) for A = 1- P( x < 43000) = 1 - 0.9772 = 0.0228

P(x > 43000) for B = 1 - P(x< 43000) = 1 - 0.7734 = 0.2266

Therefore the probability is greater with company B that will likely get an offer of $43,000 or more.

Answer:

x = 0

Step-by-step explanation:

−7(x−3)−27=−6

(-7*x -7*-3) - 27 = -6

-7x + 21 - 27 = -6

-7x - 6 = -6

-7x = 6 - 6

-7x = 0

x = 0

check:

-7(0-3) - 27 = -6

-7*-3 -27 = -6

21 - 27 = -6

32

Step-by-step explanation:

Since the perimeter of the square is equal to the angle x, then we can simply just solve for the perimeter. In this case, it will be 8 + 8 + 8 + 8, which equals 32.

Remember: The lengths of the square are all equal.

Step-by-step explanation:

So my way of doing it is to simply put 20% in decimal so

20= 0.20

Then multiply that by 70

0.20× 70 = 14%

There are probably other ways to do it but I find this way easier

Answer:

128 pieces can be made after cutting the chain

Solution:

Given that, Amy cut 32 ft of chain into pieces that were each 1/4 ft long

To find: Number of pieces after cutting the chain

From given,

total length of chain = 32 feet

length of 1 piece = 1/4 feet

Thus the number of pieces after cutting the chain can be found by dividing the total length of chain by length of 1 piece

number of pieces = total length of chain/length of 1 piece

Substituting the values, we get

number of pieces =  [tex]\frac{32}{1/4}[/tex]

number of pieces = 32 x 4 =128

Thus 128 pieces can be made after cutting the chain

Answer:

(-4,0)

Step-by-step explanation:

1. First, let's graph f(x) = |x + 4|.

(The image is below the explanation).

2. As you can see, the line at first starts going down, but then the turning point occurs at (-4,0). The graph then continues to go upwards.

Therefore, the answer is (-4, 0).

Answer:

yes -2 is less then 18 because negative is below zero

Answer: Yes, -2 is less than 18.

Step-by-step explanation:

A negative number will always be less than a positive number, so, yes, -2 is less than 18.

$6462.5

Simple Interest = (Principal × Rate × Time) / 100

SI = (P×R×T) / 100

P = 5500

R = 3.5

T = 5

[substitute the values into the formula]

SI = (5500 × 3.5 × 5) / 100

SI = 96250 / 100

SI = 962.5

Total = Principal + Simple Interest

T = P + SI

T = 5500 + 962.5

T = 6462.5

The total value of the account after 5 years will be $6462.5

Answer:

0.73

Step-by-step explanation:

the probability that it is not X is 1-0.4 = 0.6

The probability that it is not Y is 1-0.5 = 0.5

The probability that it is not Z is 1-0.1 = 0.9

So the probability that it is not any of these is

0.6x0.5x0.9 = 0.27

So the probability that it is X Y or Z is 1-0.27 = 0.73

Answer:

-2

Step-by-step explanation:

As per the provided information in the given question, we have a linear equation. We have to find the value of x.

Basically, transposition method is used to solve a linear equation in one variable containing constants and variables. We just transpose the values from RHS to LHS by changing its arithmetic operators. In this way, we solve for the unknown value. During transposing the values, ( + ) changes to ( – ) and vice-versa ; ( × ) changes to ( ÷ ) and vice-versa.

Now, coming back to the question. We have,

[tex]\longmapsto \rm { 3x = \dfrac{x}{2}- 5} \\ [/tex]

Taking the LCM in RHS and performing subtraction.

[tex]\longmapsto \rm { 3x = \dfrac{x - 10}{2}} \\ [/tex]

Transposing 2 from RHS to LHS. Its arithmetic operator will get changed.

[tex]\longmapsto \rm { 3x \times 2 = x - 10} \\ [/tex]

Performing multiplication in LHS.

[tex]\longmapsto \rm { 6x = x - 10} \\ [/tex]

Transposing x from RHS to LHS. Its arithmetic operator will get changed.

[tex]\longmapsto \rm { 6x - x = - 10} \\ [/tex]

Performing subtraction of the terms in LHS.

[tex]\longmapsto \rm { 5x = - 10} \\ [/tex]

Transposing 5 from LHS to RHS. Its arithmetic operator will get changed.

[tex]\longmapsto \rm { x = \cancel{\dfrac{- 10}{5}}} \\ [/tex]

Dividing –10 by 5.

[tex]\longmapsto \underline{\boxed{\bf { x = - 2}}} \; \bigstar \\ [/tex]

Therefore, the value of x is –2.
