5 pencils and 3 pens costs £11.
4 pencils and 6 pens costs £16.
Find the cost of a pencil.
Find the cost of a pen.

Answers

Answer 1

Answer:

The pencil is £1 and the pen is £2

Step-by-step explanation:

Let the pencil be p and let the pen be f.

5p + 3f = 11

4p + 6f = 16

the top one multiplies by two:

10p + 6f = 22

4p + 6f = 16    subtract

6p = £6

pencil = £1

Then you substitute the value of the pencil into the equation and find the value of the pen.

What do the differences between the points (as shown on the graph) represent?
Please answer

Answers

Answer:

Answer:

They represent the rise and run of the graph.

Step-by-step explanation:

Step-by-step explanation:

The difference between the x-axis of the points represents the "run" of the graph (or how much you should run along x-axis to get to the next point.)

The difference between the y-axis of of the points represents the "rise" of the graph (or how much you should rise up the y-xis to get to the next point).

The ratio of rise to run is the slope of the graph, which tells us  how many steps should we take on the y-axis for every step we move forward on the x-axis.

They represent the rise and run of the graph.  

The difference between the x-axis of the points represents the" run" of the graph( or how  important you should run along x-axis to get to the coming point.)  The difference between the y- axis of of the points represents the" rise" of the graph( or how  important you should rise up the y- x is to get to the coming point).  

The  rate of rise to run is the slope of the graph, which tells us how  numerous  way should we take on the y- axis for every step we move forward on the x-axis.

Answers

10 inches because diameter is double the radius

Answer:

10 Inches

Henry is three more than twice Nicholas’ age. Marcus is 9 less than six times Nicholas’s age. If Henry and Marcus are twins, how old is Nicholas?

Answers

Answer:

Step-by-step explanation:

Henry is 3 more than twice Nicholas' age. You can write this as :

H = 3 + 2N

Marcus is 9 less than 6 times Nicholas' age:

M = 6N - 9

Since Henry and Marcus are twins, this means H = N.

3 + 2N = 6N - 9

Add 9 to both sides

12 + 2N = 6N

Subtract 2N from both sides

12 = 4N

Divide both sides by 4 to find N.

N = 12/4 = 3

Find the value of x.
1)
59
(6x + 5)

Answers

Answer:

Is 59 equal to (6x + 5)?

If so than your answer is: x = 9 [The value of x is 9]

Explanation:

Given 59 = (6x + 5), x is the value that makes 59 = 59.

Therefore:

59 = (6x + 5)

*given*

59 =(6x + 5)

-5 -5

*subtraction property of equality*

54 = 6x

÷6 ÷6

*division property of equality*

9 = x

x = 9

*symmetric property of equality*

_________________________

To check just substitute, simplify, and make sure 59 = 59:

x = 9 → 59 = (6x + 5) → 59 = (6(9) + 5) → 59 = (54 + 5) → 59 = 59

As an accountant, you have calculated income taxes for a customer for the last 3 years. During those three years, the customer made a tax payment of $1,250, received a tax refund of $550, and made a tax payment of $925. The customer also paid a processing fee of $60 each year.

Answers

Answer:

The total amount customer paid during those 3 years  is $1685

Step-by-step explanation:

We are supposed to find the total amount customer paid during those 3 years

Customer made a tax payment = $1250

He received a refund of amount = 550

So, amount paid by him = 1250-550

Amount paid by him ==700

Now again He made a tax payment = $925

Processing fee = $60

So, Total Amount paid by him =700+925+60

Total Amount paid by him =1685

Hence the total amount customer paid during those 3 years  is $1685
