Answer:4

Step-by-step explanation:

Answer 2

Answer:

x=4

Step-by-step explanation:

8+x=12

We simplify the equation to the form, which is simple to understand  

8+x=12

We move all terms containing x to the left and all other terms to the right.  

+1x=+12-8

We simplify left and right side of the equation.  

+1x=+4

We divide both sides of the equation by 1 to get x.  

x=4

Gabby bought a backpack and 3 notebooks for $40.66. What is the total tax if the rate is 8%?

Answers

Answer:

It's $3.25 in tax

Step-by-step explanation:

Answer:

$3.24

Step-by-step explanation:

You would first have to figure out the cost of each notebook with tax so you would divide 40.66 by 3

40.66/3 = 13.55

So each notebook costs $13.55 with tax. Now, I multiplied 13.55 by 0.08. I would multiply it by 0.08 because 8% in decimal form is 0.08.

13.55*0.08 = 1.08

I got the answer 1.08. 1.08 is the tax for each notebook so I would multiply it by 3 to figure out the total tax.

1.08*3 = 3.24

Hence, the total tax is $3.24.

Susan works as a plumber. She takes calls and goes to people's houses to fix things. She charges $15 flat fee just for coming to your home and $30 for every hour she is there repairing. Susan also has a competitor, Carla. She doesn't work as much as Susan and only charges $20 no matter what amount of time she is repairing. The inequality is 30x+15>20. The answer to this solution is x>1/6. You solve this by moving the constant to the right and changing it's sign, subtracting the two numbers, and dividing both sides by 30x to get x>1/6. On the number line it will appear as a closed circle on 1/6 on the number line (less than one) and an arrow going right.

Use the table to answer the following questions.

Time (hours) Distance (miles)
2 90
3 135
5 225
6 270
1. Find the constant of proportionality.

2. Use the constant of proportionality to write a unit rate for the data in the table.

3. Write an equation to represent the relationship between time, t, and distance, d.

Answers

Answer:

Sure, here are the answers to your questions:

The constant of proportionality is 45. This is because the ratio of distance to time is always 45. For example, 90/2 = 45, 135/3 = 45, 225/5 = 45, and 270/6 = 45.

The unit rate is 45 miles per hour. This is because the constant of proportionality is 45, and the units of time are hours and the units of distance are miles.

The equation that represents the relationship between time, t, and distance, d, is d = 45t. This is because the constant of proportionality is 45, and the equation for a direct proportion is y = kx, where y is the distance, x is the time, and k is the constant of proportionality.

Here are the steps that I used to solve the problem:

I first looked at the table and noticed that the ratio of distance to time was always the same. This is a clue that the relationship between distance and time is proportional.

I then calculated the constant of proportionality by dividing the distance by the time for each pair of values. For example, I divided 90 by 2 to get 45, 135 by 3 to get 45, 225 by 5 to get 45, and 270 by 6 to get 45.

I then used the constant of proportionality to write a unit rate. The unit rate is the constant of proportionality divided by the units of time. In this case, the constant of proportionality is 45 and the units of time are hours. Therefore, the unit rate is 45 miles per hour.

I then used the constant of proportionality to write an equation. The equation for a direct proportion is y = kx, where y is the distance, x is the time, and k is the constant of proportionality. In this case, the constant of proportionality is 45, so the equation is d = 45t.
