Answers

Answer:

(-∞, 6]

Step-by-step explanation:

Step 1: Write inequality

5x - 10 ≤ 20

Step 2: Solve for x

Add 10 to both sides: 5x ≤ 30Divide both sides by 5: x ≤ 6

Here we see that any value less than or equal to 6 would work.

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

Answers

10 inches because diameter is double the radius

Answer:

What is the approximate circumference of the pizza?

Answers

Answer:

47.1cm

Step-by-step explanation:

multiply 15 cm by 3.14

Given parameters:

 Radius of the pizza  = 15cm

  [tex]\pi[/tex]   = 3.14

Unknown:

Approximate circumference of the pizza = ?

Solution:

 The pizza is circular and we take the circumference of a circle to find that of the pizza;

  Circumference of a circle  = 2  [tex]\pi[/tex] r

Input the parameters and solve;

           Circumference of a circle  = 2 x 3.14 x 15  = 94.2cm

The circumference of the pizza is  94.2cm

Answers

Answer and Step-by-step explanation: An equation represents proportional relationship when dividing the quantities of the equation results in a quotient that is always the same. For example, in general:

Equation: y = mx

[tex]\frac{y}{x}[/tex] = m

m is a constant value, which means is the same.

A. Equation: 120 - x = L

Equation from alternative A is NOT proportional since the division of the quantities doesn't result in a constant.

B. Equation: 1.08p = t

Dividing total cost per item's price, will always give the sales tax, which is constant. So, this equation IS proportional.

[tex]\frac{t}{p}=1.08[/tex]

C. Equation: [tex]x=\frac{m}{4}[/tex]

This equation is proportional because dividing marbles per how much each sister gets, always gives the number of sisters:

[tex]\frac{m}{x}=4[/tex]

D. Equation: [tex]V=12s^{2}[/tex]

This equation is NOT proportional because side length is squared, so it is not constant linearly.

Answer:

Step-by-step explanation:

A. Equation: 120 - x = L

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

Select the correct answer.

Answers

Answer:

Accounts receivable in January = $68,432.60

Accounts receivable in February = $55,929.20

Accounts receivable in March = $55,958.95

Step-by-step explanation:

65% of sales collected in the month of sales + 25% in the following month + 10% in second month after sales.

In January, total accounts receivable will be the amounts outstanding or unpaid by the end of January. By the end of January, a total of 10% of December sales & 35% of January sales remain outstanding.

Accounts receivable in January = 35% of January sales + 10% of December sales

Accounts receivable in January = (35% * $124298) + (10% * $249283)

Accounts receivable in January = $43504.3 + $24928.3

Accounts receivable in January = $68432.60

In February, total accounts receivable will be the amounts outstanding or unpaid by the end of February. By the end of February, a total of 10% of January sales & 35% of February sales remain outstanding.

Accounts receivable in February = 35% of February sales + 10% of January sales

Accounts receivable in February = (35% * $124284) + (10% * $124298)

Accounts receivable in February = $43,499.4 + $12,429.8

Accounts receivable in February = $55,929.20

In March, total accounts receivable will be the amounts outstanding or unpaid by the end of march. By the end of March, a total of 10% of February sales & 35% of March sales remain outstanding.

Accounts receivable in March = 35% of March sales + 10% of February sales

Accounts receivable in March = (35% * $124373) + (10% * $124284)

Accounts receivable in March = $43530.55 + $12428.4

Accounts receivable in March = $55,958.95
