If x=3 then y=21. What is the value of x when y=105

Answers

Answer 1

Answer:

0.6

Step-by-step explanation:

If Y=105 you would divide 105 by the original Y which was 21, therefore getting 5. With that 5 we would divide 3 by 5 because that's what we did with the Y and then we get 0.6. hope this helped! xx

Answers

Answer:

The three numbers are 19, 18, and 31.

Step-by-step explanation:

The three numbers are x, y, and z.

y=x-1

z=2y-5

z=x+12

2y-5=x+12

2(x-1)-5=x+12

2x-2-5=x+12

x=19

y=18

z=31

The three numbers are 19, 18 and 31

what is Algebra?

Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.

let the three numbers be x, y, and z.

So, according to question

The second of three numbers is one less than the first,

y = x-1

The third number is 5 less than twice the second,

z=2y-5

also, If the third number exceeds the first number by

12z=x+12

Now, equating the equations

2y-5=x+12

2(x-1)-5=x+12

2x-2-5=x+12

x=19

So, y=18 and z=31.

A gardener is installing fence around his garden. Let x represent the width of the garden, in feet. The perimeter of the garden is 8x + 8. Which expression represents the length of the garden?

1. 2x + 2

2. 3x + 4

3. 6x + 8

4. 8x + 8 – 2x

Answers

Answer:

2.        3x + 4

Step-by-step explanation:

What we know:

w=x

Perimeter (p) = 8x+8

Formula for perimeter  p =2(L+W)

8x+8 =  2(L+W)

L+W is half, so    

 L+W = 4x+4

Substract W on both sides;

L = 4x+4 -W    

We know that  W = x

So

L= 4x+4-x

4x-x= 3x

L= 3x+4

*x=-5,y=2

*x=4,y=3

please answer step by step

Answers

Answer: x=4 and y=-3

Step-by-step explanation:

To use elimination to solve system of equations, you want to make sure the equations are first in standard form.

2x+4y=-4

3x+5y=-3

We want to make sure either the x or the y are equal so we can eliminate them. Let's eliminate x.

2x+4y=-4            [multiply equation by 3]

3x+5y=-3            [multiply equation by 2]

6x+12y=-12

6x+10y=-6

We can now subtract the equations.

2y=-6                  [divide both sides by 2]

y=-3

Now that we know y=-3, we can plug it into an equation to solve for x.

2x+4y=-4            [plug in y=-3]

2x+4(-3)=-4        [multiply]

2x-12=-4             [add both sides by 12]

2x=8                   [divide both sides by 2]

x=4

The final answer is x=4 and y=-3.

Two rival dry cleaners both advertise their prices. Store A's prices are modeled by the expression 30x - 8, where x is the number of items brought in. Store B's prices are modeled by the expression 6(5x + 3), where x is the number of items brought in. When do the two stores charge the same rate?​

Answers

Store A's prices are represented by the expression 15x - 2.

Store B's prices are represented by the expression 3(5x + 7).

To find when the 2 stores charge the same rate , we set the expression equal and solve for x

15x - 2 = 3(5x+7)

15x -2 = 15x + 21

Subtract 15x on both sides

-2 = 21

We cannot solve for x

So , the price of two stores never be same

The temperature of a cup of hot chocolate and the length of time it sits. The amount of rainfall on Fridays.

Answers

Answer:

The correct option is;

The price of a pizza and the number of toppings added

Step-by-step explanation:

A positive correlation is one in which the variables being correlated, progress in the same direction, such that an increase in one variable will lead o an increase in the other variable;

The price of a pizza  depends on the size of the pizza and the price increases for each additional topping added, such that the price of the pizza will increase as the number of toppings is increased

The variable, the height of the candle and the variable, the length of time it stays on, are positively correlated because, the two variables depends on each other whereby the time it takes to completely burn a candle increases as the length of the candle increases, however, the candle can be put out depending on usage, even if it can stay lit for a longer period of time.

The last option matches the correct solution

Step-by-step explanation:

Equation Solving

We have the following equation:

[tex]\displaystyle V=\frac{4}{3}\pi r^3[/tex]

And it's required to solve it for r.

Solving this equation needs to perform some operations to have the r isolated from any other variables or constants.

It can be done by conveniently operating on both sides as follows:

Eliminate the denominator by multiplying by 3:

[tex]\displaystyle 3V=4\pi r^3[/tex]

Move [tex]4\pi[/tex] to the other side by dividing by [tex]4\pi[/tex]:

[tex]\displaystyle \frac{3V}{4\pi}= r^3[/tex]

Swapping sides to have r at the left side:

[tex]\displaystyle r^3=\frac{3V}{4\pi}[/tex]

Finally, take the cubic root and leave r alone:

[tex]\displaystyle r=\sqrt[3]{\frac{3V}{4\pi}}[/tex]

Which of the equations below can be solved by square roots? How would you solve the other equation? Explain your reasoning. Give the solutions to both equations. Equation A: x? - 9x = 0 Equation B : x2-9=0​

Answers

Answer:

Equation A is factoring, x=9 and x=0

Equation B is the square root, x=3

The equation A:  x² - 9 = 0 can be solved by square root method

The equation B: x²  -  9x = 0 can only be solved by factoring

The given equations are:

Equation A:    x²  -  9x = 0

Equation B:    x²  -  9 = 0

The equation x² - 9 can be rewritten as:

x²  -  3² = 0

This is a difference of two squares which can be further expressed as:

(x  -  3)(x + 3) = 0

x  - 3  =  0

x  =  3

x  +  3  = 0

x  =  -3

This shows that the equation x² - 9 = 0 has two roots x = -3 and x = 3

Also, from x² - 9 = 0

[tex]x = \pm\sqrt{9} \\\\x = \pm3[/tex]

For the equation x²  -  9x = 0

This can be factored as x(x - 9) = 0

x  = 0,  x = 9

This is not solved by the square root method.

Therefore, the equation x² - 9 = 0 can be solved by square root method
