| x | = 2

| x | is absolute value of x, which may be +ve, or, -ve as well.

x can be 2, or - 2.

Answer:

First, we need to find how many books there are in each group;

If we look at group 1, they have 18 books.

If we look at group 4, they have 9 books. (We got this because they have 6 whole books, and they have half of a those 6 books which is 3 books in the other book symbol, so combined: 6 + 3 = 9)

18(group 1) - 9(group 4) = 9, group 1 read 9 more books.

Answer:

1. $56,000

2. $3,695

3. $1,644.48

Step-by-step explanation:

1. Equity = valuation - mortgage

              = $250,000 - $180,000

              = $70,000

80% = 80/100 = 0.8

Therefore, 80% of the equity = 0.8 × $70,000

                                                = $56,000

2. Total charges = jewelry charge + electronics charge

                            = $2,450 + $1,245

                            = $3,695

3.

First credit card:

Total payment = two years × monthly payments

                        = 2 × 12 × $252.04

                        = $6,048.96

Interest = total payment - balance

             = $6,048.96 - $5,000

            = $1,048.96

Second credit card:

Total payment = two years × monthly payments

                        = 2 × 12 × $381.72

                        = $9,161.28

Interest = total payment - balance

             = $9,161.28 - $7,500

             = $1,661.28

Home equity loan:

Total payment = two years × monthly payments

                        = 2 × 12 × $565.24

                        = $13,565.76

Interest = total payment - balance

             = $13,565.76 - $12,500

             = $1,065.76

Money saved = (total of interest from credit cards) - home equity loan interest

                      = ($1,048.96 + $1,661.28) - $1,065.76

                      = $1,644.48

Answer:

[tex](-3, 5)[/tex]

Step-by-step explanation:

Isolate x from the first equation:

[tex]x=\frac{11-4y}{3}[/tex]

Now, substitute it in  the second equation:

[tex]\begin{bmatrix}2\cdot \frac{11-4y}{3}+y=-1\end{bmatrix}[/tex]

This gives you:

[tex]\begin{bmatrix}\frac{22-5y}{3}=-1\end{bmatrix}[/tex]

So, you conclude: y = 5

Next, we substitute y = 5 into [tex]x=\frac{11-4y}{3}[/tex]

So, we get:

[tex]x=\frac{11-4\cdot \:5}{3}[/tex]

Then:

[tex]x=-3[/tex]

An Algebraic Expression that models the situation is [tex]4750+p-c-d+r[/tex]

Step-by-step explanation:

Beginning balance of Jennifer=$4750

Now she deposits a paycheck = p

So, New balance = 4750+p

Now she writes a check = c

Remaining balance = 4750+p-c

Now she writes a check = d

Remaining balance = 4750+p-c-d

Now refunded some money (r) for returning a pair of shoes she bought.

New balance = 4750+p-c-d+r

Hence  an Algebraic Expression that models the situation is [tex]4750+p-c-d+r[/tex]

Answer:

so graph your first point. (x=2, y=1)

Step-by-step explanation:

Your 5/3 is your rise over run. So go up 5 from 2 you should be at 7 and over 3 from your 1  so your next point would be (x=7, y=4) now get a ruler and connect your two points. make sure to use a ruler to make your line straight.  

To graph a line with a slope of 5/3 and passes through the point (2, 1), we can use the slope-intercept form of a linear equation, which is given by:

y = mx + b

where:

- y and x are the coordinates of any point on the line

- m is the slope of the line

- b is the y-intercept (the point where the line crosses the y-axis)

Given the slope (m = 5/3) and the point (2, 1), we can substitute these values into the equation and solve for the y-intercept (b):

1 = (5/3)(2) + b

1 = 10/3 + b

To isolate b, we subtract 10/3 from both sides:

1 - 10/3 = b

-7/3 = b

Now we have the values of m and b, so we can write the equation of the line:

y = (5/3)x - 7/3

To graph the line, we plot the y-intercept at (0, -7/3), and then use the slope (5/3) to find additional points on the line.

Since the slope is positive, we can move up 5 units vertically and 3 units horizontally from the y-intercept to find another point. We repeat this process to find more points if needed.

Thus, using this, one can plot the graph.

Answer:

A 5/6 ÷ 1/12 = 10

Step-by-step explanation:

Let the full tank be represented with 'Y'

Feliz's car is 5/6 full

Whenever he drives To and From work he uses 1/12 of the full tank gas.

That is 1/12 of y

Since the tank was 5/6 full before his journey to and from work, the number of time he can use the gas will be

5/6 ÷ 1/12

5/6×12/1

= 10

Feliz can drive to or from work with his gas tank 10 times.

Newton's third law states that if object A exerts a force on object B, object B must respond with a force of equal size and in the opposite direction. This law reflects nature's symmetry: forces always exist in pairs, and one body cannot exert a force on another without experiencing one.

The distributive property of multiplication over addition can be used when you multiply a number by a sum. For example, suppose you want to multiply 3 by the sum of 10 + 2. 3(10 + 2) = ? According to this property, you can add the numbers and then multiply by 3.

The sequence a_n = -2 - 51n is an arithmetic sequence

The 11th term of the sequence is -563

The nth term of the sequence is given as:

a_n = -2 - 51n

Substitute 11 for n to calculate the 11th term of the sequence

a11 = -2 - 51 * 11

Evaluate the product

a11 = -2 - 561

Evaluate the difference

a11 = -563

Hence, the 11th term of the sequence is -563

============================================================

Explanation:

Think of "eighths" as the name of a coin type.

The fraction 5/8 means "5 eighths" which we can think of as "5 coins".

Similarly, 1/8 can be thought of as "1 coin" because of 1 in the numerator.

We have two coins of the same type (both "eighths") which means we can combine the coin counts to get 5+1 = 6 coins total.

In other words, 1/8 + 5/8 = (1+5)/8 = 6/8

This is why we add the numerators but keep the denominators the same. If the denominators were different, then we cannot combine the fractions until we get them to the same denominator (such as the LCD).

Having different denominators is like adding apples to oranges. Unless we can somehow get them to the same unit, then adding wouldn't make much sense.

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

After adding, we need to reduce the result.

The numbers 6 and 8 have the common factor 2.

Divide each by this common factor.

You can write it like this if you wanted:

[tex]\frac{6}{8} = \frac{6 \div 2}{8 \div 2} = \frac{3}{4}[/tex]

Or in short,

[tex]\frac{6}{8} = \frac{3}{4}[/tex]

If you cut a pizza into 8 slices, and eat 6 of them, then it's the same as eating 3 out of 4 total slices. That's one visual way to represent the fraction 6/8 turning into 3/4.

Answer:

1/6

Step-by-step explanation:

There are 4 primes. So the probability for the first draw is 4/9. Since the card is not replaced, the second probability is 3/8. 3/8 * 4/9 is 12/72, which simplifies into 1/6.

Answer:

1/6

Step-by-step explanation:

There are 4 possible primes: 2, 3, 5, 7

First card has 4/9 probability of being a prime. Second card has 3/8 probability of being a prime(since 3 prime cards left and 8 total cards left because we do not replace the first card). 4/9 * 3/8 = 1/6.

Another way to do this is using combinatorics. C(9,2) = 36 ways to choose 2 distinct cards, C(4,2) = 6 ways to choose two of the "prime" cards. 6/36 = 1/6.
