The sales tax in one state is 5%. Write a function rule for finding the total cost of an item with selling price x. Then find the total cost of a CD player with a selling price of $110.
A. FX) 1.05x; $115.50
B. f(x) = 0.05x; $5.50
C. FX) 5 + x;$111.05
D. f(x) = x - 5; $108.95

Answer:

X=6

Step-by-step explanation:

5(x-1)+3x=7(x+1)

5x-5+3x=7x+1

8x-5=7x+1

8x-7x=1+5

X=6

So the answer is X=6

Answer:

D

Step-by-step explanation:

Answer:

Part A

x = 4

Part B

10 - 2x = 7 + 5x (x = 4)

6 - 5x = 3 + 2x (x = 4)

7 - 3x = 4 + 6x (x = 6)

6x - 2x² = 3x + 5x² (x = 3x/7) I'm not sure what step is next though

hope this helps.

Answer:

Remove parentheses.

y-10=-3\times -2y−10=−3×−2

2 Simplify 3\times -23×−2 to -6−6.

y-10=-(-6)y−10=−(−6)

3 Remove parentheses.

y-10=6y−10=6

4 Add 1010 to both sides.

y=6+10y=6+10

5 Simplify 6+106+10 to 1616.

y=16y=16

Answer:

2d≤24

Step-by-step explanation:

Total number of bottled juice bought = 24 bottles

Amount she drank each day = 2 bottles

To get the inequality to represent greatest number of days she can continue before she has to replenish her stock, we will say;

1 day = 2 bottles

d days = 24 bottles

Cross multiply

2 * d = 1 * 24

2d = 24

Since we want to know the greatest number of days she can continue before she has to replenish her stock, the equal to to sign will be replaced with less than or equal to sign as shown;

2d≤24

This shows that the maximum number of days she can continue before replenishing is 12days. It cannot exceed

Answer:

14 is the answer have a nice day

Answer: 17/18

Step-by-step explanation: Multiply the amount of containers and the amount of cups in each container. Subtract 3. This is 51 out of 54, simplify this and get 17 out of 18.

Answer:

the answer is 1/18

Step-by-step explanation:

6×9=54-3=51.

One third and two thirds are too large for the amount he ate, so is 17/18s.

The subtraction process for the operation, 9.318 - 4.265 gives;

A = 0.2, and B = 0.11

The given operation is a subtraction of 4.165 from 9.318,

The numbers can be arranged as follows;

AB

9.318

-4.165

The subtraction process is as follows:

Subtracting the numbers that have the same place values, gives;

Subtract the 0.005 from 0.008 to get 0.003 which

In the subtraction process, the 0.06 cannot be subtracted from the 0.01 on top of it.

To subtract, 0.1 is borrowed from 0.3 to give 0.3 - 0.1 = 0.2 and the borrowed 0.1 is added to 0.01 to give, 0.1 + 0.01 = 0.11

Therefore;

A = 0.2 and B = 0.11

The subtraction process is therefore;

Answer:

B. [tex] n = 16p [/tex]

Step-by-step explanation:

number of ounces = n

number of pounds = p

There are 16 ounces in 1 pounds (unite rate: 1 pounds = 16 ounces)

Therefore, there would be n ounces in p pounds

Set a proportion to find n.

16 : 1 = n : p

[tex] \frac{16}{1} = \frac{n}{p} [/tex]

Multiply both sides by p

[tex] \frac{16}{1} \times p = \frac{n}{p} \times p [/tex]

[tex] \frac{16 \times p}{1} = n [/tex]

[tex] 16p = n [/tex]

Answer:

3 cm²

Step-by-step explanation:

Given that:

5/8 of rectangle = red

Let area of rectangle = x

Each piece = 1/16 of whole rectangle

Area of whole rectangle = 48 cm²

Area of each piece = 1/16 of 48

1/16 * 48cm²

= 48 / 16 cm²

= 3 cm²

Hence area of each piece = 3cm²

21, 24, 29

Step-by-step explanation:

To calculate the first 3 terms, substitute n = 1, 2, 3 into the rule, that is

a₁ = 1² + 20 = 1 + 20 = 21

a₂ = 2² + 20 = 4 + 20 = 24

a₃ = 3² + 20 = 9 + 20 = 29

Answer:

I got D

Step-by-step explanations

I did y2-y1/x2-x1

I did 40-25/5-2 which will equal to 15/3=5

then I did 25=2x+b

25=2(5)+b

25=10+b

subtract 10

then you will get 15

So it will be y=5x+15

Step-by-step explanation:

because 2 cups of flour turned to 20 cups is to 14 cups of sugar to 140 cups

so the ratio goes from 2: 14 to 20: 140

Given:

The kiddie pool is 7 feet long. The adult swimming pool is 42 feet long.

To find:

How many times as long as the kiddie pool is the adult swimming pool?

Solution:

Let adult swimming pool is x times the kiddie swimming pool.

[tex]42=x\times 7[/tex]

[tex]42=7x[/tex]

Divide both sides by 7.

[tex]\dfrac{42}{7}=\dfrac{7x}{7}[/tex]

[tex]6=x[/tex]

Therefore, adult swimming pool is 6 times the kiddie swimming pool.

Answer:

5/4

Step-by-step explanation:

First plot any2 points. Next count how many units it is High and Left/Right to get to the second point!

(Added your graph for further explaination :)

First, determine 2 points on the graph. I'd recommend to choose 2 points that are next to each other to make it easier.

Second, see how many units higher the first point you chose (on the left) is than the second point you chose (on the right). Say it is 3 units, then you mark a points 3 units above the first point.

Third, see how many units to the right the second point is to the first. If it is 5 units, you would go to the point you marked on the previous step, and move 5 units to the right. If you did it correctly, it should end up on the second point you chose. The segment you drew should kind of look like a box.

Now, make a proportion. Put how many units you rose in the second step at the top, and how many you ran at the bottom. Treat this like a fraction and simplify. You have your slope!

Going higher and to the right is the formula rise/run. How many units do you rise, how many do you go right? I recommend doing this when finding slope on a graph
