I forgot how to solve this equation for both answers already :( I will be very much appreciated if I could get a step by step clear solution for both answers!

Based on the calculations, the number of books that were bought by Hugh are 4 books.

In order to determine the number of books that were bought by Hugh, we would substitute the value of the number of magazines into the given equation and then evaluate as follows:

3.95m + 8.95b = 47.65

3.95(3) + 8.95b = 47.65

11.85 + 8.95b = 47.65

8.95b = 47.65 - 11.85

8.95b = 35.8

b = 35.8/8.95

b = 4.

In conclusion, the number of books that were bought by Hugh are 4 books.

The required polynomial is [tex]x^{3}-7x^{2} -20x+96[/tex]

Polynomial : If in an expression all of variables, constants and exponents are present with mathematical operations like addition, multiplication, subtraction & division, then it is called polynomial.

If a polynomial has degree 3 as a highest degree, then the polynomial is called degree 3 polynomial or cubic polynomial.

A degree 3 polynomial having zeros α, β, γ and the coefficient of x³ equal a is,  a(x- α)(x- β)(x- γ)

Given, Zeros of the polynomial are -4, 3, 8 & coefficient of x³ equal 1.

Answer:

its 69.8

Step-by-step explanation:

For a solution to be the solution to a system, it must satisfy all the equations of that system. There exists no solution for the system of equations.

For a solution to be the solution to a system, it must satisfy all the equations of that system, and as all points satisfying an equation are in their graphs, so solution to a system is the intersection of all its equation at a single point(as we need a common point, which is going to be the intersection of course)(this can be one or many, or sometimes none)

For the three equations,

2x−2y+6z=16

3x+3y−4z=−5

x−y+3z=9

Solve the first equation for x,

2x−2y+6z=16

x = 8 + y - 3z

Now substitute the value of x in both the equations, if the two equations are satisfied, then the equation will have a solution, if it's not then no solution exists.

[tex]3\left(8+y-3z\right)+3y-4z=-5\\6y-13z+24=-5\\\\\\ 8+y-3z-y+3z=9\\ 8=9[/tex]

Answer:

  (x, y) = (16/3, -1/9)

Step-by-step explanation:

A system of two linear equations can be solved a number of ways. One of the easiest is by graphing. Algebraic methods usually work better when the equations are in standard or general form.

A graphing calculator can work with the given equations. The solution it shows in the first attachment is ...

  (x, y) = (16/3, -1/9)

An algebraic method of solving a pair of linear equations can start with them in general form. We can obtain that form by subtracting one side of the equation from both sides. Here, we choose to do that so the coefficient of x is positive.

First equation

  5(x -3y) -6 -(4x +1) = 0 . . . . . . . subtract (4x+1) from both sides

  5x -15y -6 -4x -1 = 0 . . . . . . eliminate parentheses

  x -15y -7 = 0 . . . . . . . . . . collect terms

Second equation

  3(x +6y) +4 -(9y +19) = 0 . . . . . . subtract (9y+19) from both sides

  3x +18y +4 -9y -19 = 0 . . . . . . eliminate parentheses

  3x +9y -15 = 0 . . . . . . . . . . . collect terms

  x +3y -5 = 0 . . . . . . . . . . . remove common factor of 3

We notice the coefficients of x and y are related by convenient factors, so we can use the "elimination method" to solve these equations. Subtracting the first from the second, we get ...

  (x +3y -5) -(x -15y -7) = 0 -0

  18y +2 = 0 . . . . . . collect terms

  y +1/9 = 0 . . . . . . . divide by 18, reduce the fraction

  y = -1/9

Using this in the second equation, we have ...

  x +3(-1/9) -5 = 0

  x = 5 1/3

The solution to the system of equations is (x, y) = (5 1/3, -1/9).

Using a system of equations, the meaning of point R is given as follows:

A number of books and their cost where both subscriptions cost the same.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable. In a graph, the solution to the system is the intersection point of the two equations.

In this problem, the point R is the point in which:

3y = 96.

That is, the point in which the prices are equal, hence:

The initial start-up fee for signing up with Rita's lawn mowing service is $20, using simultaneous equations.

Simultaneous equations are two or more algebraic equations that share variables like x and y and can be solved at the same time.

Let y = fixed cost (initial start-up cost)

Let x = variable cost per lawn mowing

Equation 1: Customer A = y + 10x = $370

Equation 2: Customer B = y + 7x = $265

Subtract equation 2 from equation 1 to get:

3x = $105

x = $35

Substitute x in any of the two equations to find the value of y, thus:

Customer A:

y + 10($35) = $370

y + #350 = $370

y = $20 ($370 - $350)

Thus, the initial start-up fee for signing up with Rita's lawn mowing service is $20, using simultaneous equations.

Compare 32/35 and 9/10.

Comparing 32/35 and 9/10 we have 32/35 is greater than 9/10, that is 32/35 > 9/10.

Fraction is the ratio of two numbers. The upper number is called Numerator and the Lower number is called the Denominator.

We know that if the denominators are the same for two fractions then which has the greatest numerator is a greater fraction than the other.

Given the fractions are 32/35, 9/10

To compare this two fractions we have to make denominators equal first.

LCM of 10,35 = 70

Calculating the fractions,

32/35 = (32*2)/(35*2) = 64/70

9/10 = (9*7)/(10*7) = 63/70

Since 64 > 63

So 64/70 > 63/70

The flavor of candy that is most likely to be picked is the flavor with the highest probability.

To find the highest probability, order the decimals from smallest to largest.  When ordering decimal numbers, always compare the digits immediately after the decimal point first, i.e. the 'tenth place'.

Therefore, from inspection of the table, the probabilities in order of smallest to largest are:  0.095 < 0.125 < 0.21 < 0.57

So the flavor with the highest probability of 0.57, and therefore the flavor that is most likely to be picked, is butterscotch.

It is important to note that the sum of angles in a triangle equals 180°

The given structure is a triangle, thus, the angles sum up to 180°

m ∠ A + m ∠ B + m ∠ C = 180°

m∠ A = 60°

m ∠ B = 60°
