It’s not really that hard but I am just busy so please do this for me.

Step-by-step explanation:

the simplest way for me is

1. to convert both terms into full fractions (not mixed numbers).

2. then to bring both fractions to the same denominator.

3. and then do the actual calculation.

and if needed, we can

4. then convert the result back into mixed numbers.

1.

15 1/2 = (15×2 + 1)/2 = 31/2

1 11/20 = (1×20 + 11)/20 = 31/20

2.

we need to convert 31/2 into a fraction .../20, so that we can actually combine it with the 31/20.

how do we get from 2 to 20 ? by multiplying by 10.

in order to keep the value of the fraction unchanged, we need to do the same multiplication also to the numerator :

31/2 × 10/10 = 310/20

3.

310/20 + 31/20 = 341/20

4.

341/20 = (17×20 + 1)/20 = 17 1/20

to get this you do an integer division and note the remainder.

341/20 = 17 remainder 1

The student must earn a 74 on the final exam to pass the course with an average of 70.

The student's current average score is (64 + 69 + 73) / 3 = 66.

To find the score the student needs to earn on the final exam to maintain an average of 70, we can set up an equation:

(64 + 69 + 73 + x) / 4 = 70

Where x is the score the student needs to earn on the final exam.

Solving for x:

(64 + 69 + 73 + x) = 280

x = 280 - 64 - 69 - 73 = 74

So, the student must earn a 74 on the final exam to pass the course with an average of 70.

By applying the linear equation concept, it can be concluded that:

A. The slope of the line is 15

B. The standard form of the equation is 15x - y + 325 = 0

C. The function notation of the equation is g(x) = 15x + 325

D. The balance in the bank account after 12 days is $505

Linear equation is an equation that contains one or more variables, where each variable has the power of one.

The standard form of a linear equation is y - y₁ = m(x - x₁) or ax + by + c = 0, where m is the slope of the function.

Slope of the function represents the change in y (Δy) over the change in x (Δx). m = Δy / Δx

We have the following table:

x         0       5       10

g(x)   325   400   475

A. To find the slope of the line, we calculate the value of Δy  dan Δx:

Δy = y₂ - y₁

    = 400 - 325

    = 75

Δx = x₂ - x₁

     = 5 - 0

     = 5

m = Δy / Δx

   = 75 / 5

   = 15

B. To find its standard form, we can input the value of one point into y - y₁ = m(x - x₁):

            y - y₁ = m(x - x₁)

        y - 325 = 15 (x - 0)

        y - 325 = 15x - 0

15x - y + 325 = 0

C. function notation changes the y to g(x), so we get:

   15x - y + 325 = 0

15x - g(x) + 325 = 0

                  g(x) = 15x + 325

D. The balance in the bank account after 12 days can be calculated by substituting the value of x = 12 into the function:

g(x) = 15x + 325

      = 15 · 12 + 325

      = 180 + 325

      = $505

What is the linear equation in one variable?

A linear equation in one variable is an equation that can be written in the form: y = mx + b,where "x" is the independent variable, "y" is the dependent variable, "m" is the slope of the line, and "b" is the y-intercept.

Let the number of dogs be x.

1.48x - 20 = 1000
1.48x = 1020
x = 1020/1.48
x = 690

Answer: The values that make the denominator equal to zero for a rational expression are known as restricted values. How do you identify restrictions in rational expressions? The restriction is that the denominator can not be equal to zero. So in this problem, since 4x is in the denominator it can not equal zero.

The best way to report for (515 x 0.0025) is 25.86 and it is done using the concept of significant figures.

Given (515 x 0.0025) + 24.57

We are asked to report the answer in the best way. This can be done using the concept of significant figures.

We can see that 515 has 3 significant figures

0.0025 has 4 significant figures ( we have to consider the zeros after the decimal)

24.57 has 4 significant figures

Thus the best answer will have 4 significant figures.

(515 * 0.0025 ) + 24.57 = 25.8575 = 25.86

We have to round off the answer to 4 significant figures, thus it'll be 25.86 ( 5 becomes 6 because the figure next to 5 is 7, thus 5 will be rounded off to 6 )

Answer: y = -4x + 29

Step-by-step explanation:

To find the equation of the line passing through the points (-3, 17) and (2, -3), we can use the slope-point form of a line, which is given by:

y - y1 = m(x - x1)

Where (x1, y1) is a point on the line, m is the slope of the line, and (x, y) are the coordinates of any other point on the line. To find the slope of the line, we can use the formula:

m = (y2 - y1) / (x2 - x1)

Plugging in the coordinates of the two points, we have:

m = (-3 - 17) / (2 - (-3)) = -20 / 5 = -4

Next, we plug in the coordinates of one of the points and the slope into the slope-point form of a line:

y - 17 = -4(x - (-3))

Expanding the right side:

y - 17 = -4x + 12

Adding 17 to both sides:

y = -4x + 29

So the equation of the line passing through the points (-3, 17) and (2, -3) is: y = -4x + 29

Let x be the amount Pam has, then Dan has x - $3.00 and Sam has x + x - $3.00 + $1.00 = 2x + $1.00

The total amount of money they have is x + x - $3.00 + 2x + $1.00 = 31.00

So, 4x + $1.00 = 31.00

Subtracting $1.00 from both sides gives 4x = 30.00

Finally, dividing both sides by 4 gives x = $7.50

So Pam has $7.50, Dan has $7.50 - $3.00 = $4.50, and Sam has $7.50 + $4.50 + $1.00 = $13.00.

A matrix is a rectangular array of numbers, symbols, or expressions, arranged in rows and columns.

The order of a group generated by matrices a and b refers to the number of distinct matrices that can be produced by multiplying a and b a certain number of times.

To find the order of the group, we need to start by multiplying a and b and see if we get any new matrices. If we do, we keep multiplying those matrices until we get back to the original matrices a and b.

The order of the group is the number of distinct matrices we get in this process.

1.) 5/6 > 4/6

5.) 7/8 > 4/8
9.) 8/10 < 15/10
13.) 6/8 < 7/8

what is a fraction?

A fraction is a mathematical expression that represents a part of a whole or a division of one quantity into equal parts. It consists of two parts, a numerator and a denominator. The numerator represents the number of equal parts of the whole and the denominator represents the total number of parts the whole is divided into.

1.) 5/6 ___ 2/3

To compare these fractions, it's best to find equivalent fractions with a common denominator. A common denominator for 6 and 3 is 6. So, to make the denominator of 2/3 equal to 6, multiply both the numerator and denominator by 2:

2/3 * 2/2 = 4/6

Now, both 5/6 and 4/6 have a common denominator of 6. So, we can easily compare:

5/6 __ 4/6

5/6 is greater than 4/6, so the answer is 5/6 > 4/6

5.) 7/8 ___ 1/2

To compare these fractions, it's best to find equivalent fractions with a common denominator. A common denominator for 8 and 2 is 8. So, to make the denominator of 1/2 equal to 8, multiply both the numerator and denominator by 4:

1/2 * 4/4 = 4/8

Now, both 7/8 and 4/8 have a common denominator of 8. So, we can easily compare:

7/8 __ 4/8

7/8 is greater than 4/8, so the answer is 7/8 > 4/8

9.) 8/10 ___ 3/4

To compare these fractions, it's best to find equivalent fractions with a common denominator. A common denominator for 10 and 4 is 10. So, to make the denominator of 3/4 equal to 10, multiply both the numerator and denominator by 5/5:

3/4 * 5/5 = 15/10

Now, both 8/10 and 15/10 have a common denominator of 10. So, we can easily compare:

8/10 __ 15/10

8/10 is less than 15/10, so the answer is 8/10 < 15/10

13.) 3/4 ___ 7/8

To compare these fractions, it's best to find equivalent fractions with a common denominator. A common denominator for 4 and 8 is 8. So, to make the denominator of 3/4 equal to 8, multiply both the numerator and denominator by 2:

3/4 * 2/2 = 6/8

Now, both 6/8 and 7/8 have a common denominator of 8. So, we can easily compare:

6/8 __ 7/8

6/8 is less than 7/8, so the answer is 6/8 < 7/8

Hence, the equivalent fractions are
1.) 5/6 > 4/6

5.) 7/8 > 4/8
9.) 8/10 < 15/10
13.) 6/8 < 7/8
