Let's choose two arbitrary points on the graph.

For example, let these be points with coordinates (1, 5) and (2, 8).

Substitute the coordinates of these points into the above formula and derive the equation of a straight line.

$\dfrac{x-1}{2-1} =\dfrac{y-5}{8-5}\\\\\dfrac{x-1}{1} =\dfrac{y-5}{3}\\\\3(x-1)=y-5\\3x-3=y-5\\y=3x-3+5\\y=3x+2$

You borrow $10,000 to buy a car. The simple interest rate is 3%. You pay the loan off after 6 years. What is the total amount you paid for the loan?

Answers

Answer:

The total amount of money needed to pay off the car after 6 years would be $11,800.

Step-by-step explanation:

Write down the facts:

The car costs $10,000The interest rate is 3%And you finished paying the loan off after 6 years

Interest = $10,000 * 0.03 * 6

This being $10,000, 3% interest rate and over 6 years.

Interest= $1800

This amount we found is the additional amount (interest) you have to pay with the $10,000. Now, to find the total amound we add the interest and $10,000.

Total amount = 10,000 + $1800

Total amount = $11,800

Therefore the total amount paid over 6 years (including the 3% interest rate) would be $11,800. I hope this helped!!!

$11800 is the answer

It will take them 8,100 minutes.
It will take them 8,745 minutes.

Answers

Answer:

It will take them 8,100 minutes.

Step-by-step explanation:

If it takes a group of 24 students 1,296 minutes to study for an upcoming test, it takes 54 minutes for each student. (=> 1,296/24 = 54)

150 x 54 minutes = 8,100 minutes.

Hello! :)

Answer:

$\huge\boxed{751}$

Let the smallest digit, or the units' digit, be equal to x:

Tens' digit is four more, therefore:

x + 4 represents the tens' digit.

Hundreds' digit is 2 more than the tens' digit, so:

2 + (x + 4), or x + 6 represents the hundred's digit.

These all sum up to 13, so write an expression to represent this:

x + (x + 4) + (x + 6) = 13

Combine like terms:

3x + 10 = 13

Subtract 10 from both sides:

3x = 3

Divide both sides by 3:

x = 1

Find the digits using the rules listed above:

Hundreds' digit: (1) + 6 = 7

Tenths' digit: (1) + 4 = 5

Units' digit: 1 = 1

Therefore, the number is:

751.

The answer is 751

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?

Answers

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

2.5(16 ÷ 3.2 – 10(0.2) + 3) – 5.2
What will be the next step?

Answers

Answer:

division of 16 by 3.2

Step-by-step explanation:

2.5(4^2 ÷ 3.2 – 10(0.2) + 3)– 5.2

2.5(16 ÷ 3.2 – 10(0.2) + 3) – 5.2

Next, he will perform multiplication and division inside parentheses, left to right.

2.5(5 – 10(0.2) + 3) – 5.2 . . . . . Bryan's next step

2.5(5 – 2 + 3) – 5.2

Then, he will finish evaluating inside parentheses by performing addition and subtraction left to right.

2.5(3 + 3) – 5.2

2.5(6) – 5.2

With parentheses evaluated, now we do multiplication and division, left to right.

15 – 5.2

Finally, addition and subtraction left to right.
