How to solve 3x - 1/2 = 8 1/2 please no links and do it step by step

Answers

Answer 1

Answer:

[tex]x=\frac{3}{2}[/tex]

Step-by-step explanation:

Step 1.  Put each term in [tex]3x-\frac{1}{2}[/tex] over the common denominator 2.

[tex]\frac{6x}{2}-\frac{1}{2}[/tex]

Therefore we have [tex](\frac{6x}{2}-\frac{1}{2})=4[/tex]

Step 2.

Combine [tex]\frac{6x}{2}-\frac{1}{2}[/tex] into a single fraction.

[tex]\frac{6x-1}{2}[/tex]  

Therefore we have [tex](\frac{1}{2}(6x-1))=4[/tex]  or [tex]\frac{6x-1}{2}=4[/tex]

Step 3.

Multiply both sides by a constant to simplify the equation.

Multiply both sides of [tex]\frac{6x-1}{2}=4[/tex]  by 2:

[tex]\frac{2*(6x-1)}{2}=4*2[/tex]

Step 4.

Cancel the common terms in the numerator and denominator of   [tex]\frac{2*(6x-1)}{2}[/tex]

Then we get [tex]\frac{2}{2}*(6x-1)[/tex]  which simplifies to [tex](6x-1)[/tex]

So all together we have [tex](6x-1)=2*4[/tex]

Step 5.

Multiply 2 and 4 together and remove the parenthesis.

[tex]6x-1=8[/tex]

Step 6.

Isolate terms with the variable x to the left hand side.

So add 1 to both sides:

[tex]6x+(1-1)=8+1[/tex]

Evaluate   [tex]1-1=0[/tex]  which cancels out

Step 7.

Add the like terms on the right side:

[tex]6x=9[/tex]

Step 8.

Divide both sides by a constant to simplify the equation.

Divide both sides of [tex]6x=9[/tex]  by 6.

[tex]\frac{6x}{6} =\frac{9}{6}[/tex]

Any non-zero number divided by itself is 1.

[tex]x=\frac{9}{6}[/tex]  which simplifies to [tex]x=\frac{3}{2}[/tex]

The following scatter plot shows the correlation between the number of hours twelve teenagers spent in the mall and the number of dollars they spent on food or drinks while at the mall. Use the line of best fit to estimate how much money a teenager will spend on food if he or she is at the mall for three hours.

$9

$11

$7

$5

Answers

The equation of the line of best fit is an illustration of a linear function

The teenager would spend $9 on food if he or she is at the mall for three hours.

How to determine the amount spent on food?

The equation of the line of best fit is given as:

y = 2x + 3

When the teenager spends 3 hours in the mall, it means that:

x = 3

So, we have:

y = 2 * 3 + 3

Evaluate the product

y = 6 + 3

Evaluate the sum

y = 9

Hence, the teenager would spend $9 on food if he or she is at the mall for three hours.

I have 35 quarters and dimes in
my pocket. How many of each do I have if I have $5.45??
HELP Me pls

Answers

Answer:

13 Quarters, 22 Dimes

Step-by-step explanation:

.10d + .25q = 5.45

.10 (35 - q) + .25q = 5.45

3.5 - 10q + .25q = 5.45

.25q - .10q = 5.45 - 3.5

.15q = 1.95

q = 13

Plug the value of q to solve for d, or the number of dimes.

d = 35 - q

d = 35 - 13

d = 22

What is Graph?

A graph contains data of which input maps to which output.

Analysis of this leads to the relations which were used to make it.

If we know that the function crosses x axis at some point, then for some polynomial functions, we have those as roots of the polynomial.

WE have given the  graph shows the population of a city n months after the establishment of a new automobile plant in the city.

We can see that at 4000 people, the graph increases and then become constant at the rate of 7000 people.

So we can conclude that the population of the city increases rapidly for the first four months and then slowly approached 7000 people.

What is a polynomial?

Polynomial is an equation written with terms of the form kx^n.

where k and n are positive integers.

There are quadratic polynomials and cubic polynomials.

Example:

2x³ + 4x² + 4x + 9 is a cubic polynomial.

4x² + 7x + 8 is a quadratic polynomial.

We have,

To find the product of the polynomials (3x² - 2x - 3) (5x² + 4x + 5), we can use the distributive property of multiplication to multiply each term in the first polynomial by each term in the second polynomial, and then combine like terms.

We can start by multiplying the first term in the first polynomial, 3x^2, by each term in the second polynomial:

3x² (5x² + 4x + 5)

= [tex]15x^4 + 12x^3 + 15x^2[/tex]

Next, we multiply the second term in the first polynomial, -2x, by each term in the second polynomial:

-2x(5x² + 4x + 5) = -10x³ - 8x² - 10x

Finally, we multiply the third term in the first polynomial, -3, by each term in the second polynomial:

-3(5x² + 4x + 5) = -15x² - 12x - 15

Putting these three results together, we have:

(3x² - 2x - 3) (5x² + 4x + 5)

= [tex]15x^4 + 2x^3 - 3x^2 + 12x^2 - 10x^3 - 10x - 15x^2 - 12x - 15[/tex]

Simplifying and collecting like terms, we get:

(3x² - 2x - 3)(5x² + 4x + 5)

[tex]15x^4 - 8x^3 - 6x^2 - 22x - 15[/tex]

Therefore,

The product of the polynomials is [tex]15x^4 - 8x^3 - 6x^2 - 22x - 15.[/tex]
