Interpret the meaning of the expression 2x – 3. The expression 2x – 3 represents The variable x represents.

Step-by-step explanation:

Answer 2

Answer:

The x represents how many songs Sabrina has because if you are saying Nicolas has three less than twice as many as her then you are doubling the amount of songs Sabrina has and you're subtracting 3 from that to get how many songs Nicolas has. Let's say Sabrina has 29 songs. Now we are trying to find out how many songs Nicolas has. 2x-3. 2(29) - 3. 58-3. Nicolas has 55 songs if Sabrina were to have 29. I really hope this helped :)

Karl knows that 8 servings of Sour Patch kids have 3,600 calories.

1. If they eats 5 servings of Sour Patch kids, how many calories do they eat?

2. If they want to eat 675 calories of Sour Patch kids, how many servings should they eat?

3. Write an equation to represent the relationship between the number of calories (c) and the number of servings of Sour Patch kids (s).

Answers

Step-by-step explanation:

Find amount of calories in one serving

3,600 / 8 = 450

If they eats 5 servings of Sour Patch kids, how many calories do they eat?

5 * 450 = 2,250 calories

If they want to eat 675 calories of Sour Patch kids, how many servings should they eat?

675 / 450 = 1.5 servings

Write an equation to represent the relationship between the number of calories (c) and the number of servings of Sour Patch kids (s)

c = 450s

When you buy an item on which sales tax is charged,the total cost is calculated by the formula T=P+s/100p where T is the total cost,p is the items price,and s is the sales tax rate (as a percent). If you pay $14.77 for an item priced at $14, what was the tax rate ?

Answers

Given:

The formula for total cost is

[tex]T=p+\dfrac{s}{100}p[/tex]

where, p is the price of item and s is the sales tax rate (as a percent).

You pay $14.77 for an item priced at $14.

To find:

The the tax rate.

Solution:

You pay $14.77 for an item priced at $14. So,

Total cost (T) = $14.77

Price of item (p) = $14

Putting T=14.77 and p=14 in given formula, we get

[tex]14.77=14+\dfrac{s}{100}(14)[/tex]

[tex]14.77-14=\dfrac{s}{100}(14)[/tex]

[tex]0.77=\dfrac{s}{100}(14)[/tex]

Multiply both sides by 100.

[tex]77=14s[/tex]

Divide both sides by 14.

[tex]\dfrac{77}{14}=s[/tex]

[tex]5.5=s[/tex]

Therefore, the tax rate is 5.5%.

The population of a town is 24,721 and declines continuously at a rate of 2.9% each year. What is the approximate population of the town in 12 years? (5 points)


16,118


17,366


17,455


35,011

Answers

The starting population of the town is 24,721 and it's population growth rate is -2.9% per year (negative because it's declining, not growing).

Since the town loses 2.9% of its population per year, find what 2.9% of the town is and then multiply it by 12. Subtract that from the starting population to get your final answer.

So...

24,721 × 2.9% = 716.909 ≈ 717 people per year

717 × 12 = 8,604

24,721 - 8,604 = 16,117

Answer: a. 16,118

7x + 2y = 11
4x - 7y = -10 solve the system using an equivalent system (if you can pls put step by step !!!)

Answers

Answer:

x = 1, y = 2

Step-by-step explanation:

7x + 2y = 11 -----Equation 1

Equation 1 × 7:

49x + 14y = 77 -----Equation 2

-------------------------------------------------------------------------------------------------------------

4x - 7y = -10 -----Equation 3

Equation 3 × 2:

8x - 14y = -20 -----Equation 4

-------------------------------------------------------------------------------------------------------------

Equations 3 + 4:

49x + 14y + 8x - 14y = 77-20

49x + 8x = 77-20

57x = 57

x = 57 ÷ 57

x = 1

Substitute x = 1 into Equation 1.

7x + 2y = 11

7(1) + 2y = 11

7 + 2y = 11

2y = 11-7

2y = 4

y = 4 ÷ 2

y = 2
