What property was applied to solve the equation below?

0.36 x = negative 1.8
0.36 (divided by 0.36) x = negative 1.8 (divided by 0.36)
x = negative 5

Answers

Answer 1

Answer:

Division property

Step-by-step explanation:

The property which states that we can divide both side of the equation by the same non-zero number is called the division property of equality.

The goal of dividing an equation is to isolate the unknown variable on one side.

For example, let the equation be:

2×x=10

Since the unknown variable x is being multiplied by the number 2, to isolate the variable an inverse operation needs to be applied - division:

2×x÷2=10÷2

Careful! Never forget to write the same operation on both sides of the equation! When doing so, the solution of the equation stays the same, i.e. we get an equivalent equation.

Alexi bought 5 shirts. Given that each of them costs 12 dollars, we can say that the equation for their price is:

12 + 12 + 12 + 12 + 12 or just 5 x 12


Now, Alexi also bought socks. 3 pairs of them, in fact. Given that each pair was an astounding 2 dollars, we would get this equation:

2 + 2 + 2 or just 3 x 2


Of course, Alexi bought these things together, so they must pay for both things. The total price would be

5 x 12 + 3 x 2 or 66 dollars

A small tree that is 5 feet tall casts a 3-foot shadow, while a building that is 45 feet tall casts a shadow in the same direction. Determine the length of the building's shadow.

A: 9 feet
B: 10 feet
C: 15 feet
D: 27 feet

Answers

We can use proportions to find the length of the building's shadow. Let x be the length of the building's shadow. Then, we have:

5/3 = 45/x

To solve for x, we can cross-multiply and simplify:

5x = 135

x = 27

Therefore, the length of the building's shadow is 27 feet, which is option D.
the answer would be x=27

Answer:

x approximately equals 26.4

Step-by-step explanation:

\(C^{2}\) - \(B^{2}\) = \(A^{2}\)

\(29^{2}\) - \(12^{2}\) = 697

\(\sqrt{697}\) ≈ 26.4

Use the Pythagorean theorem
a^2 + b^2 = c^2
12^2 + b^2 = 29^2
144 + b^2 = 841
b^2 = 697
Find the square root of 697

A. 42 in2
B. 52 in2

D. 128 in2

Answers

Answer:

104in2

Step-by-step explanation:

The area, in square inches, of the painted face of the brick is Option C 104 \(in^{2}\).

Using the Quadrant system of the Number line

B (-4,2) lies in the 2nd quadrant.

C (-4,-11) lies in the 3rd quadrant

A (4,2) lies in the 1st quadrant

D (4,-11) lies in the 4th quadrant

Length of Side AB= Length of Side CD= Distance between x coordinate of A & B OR Between C & D i.e. 8 in

Length of Side BC= Length of side  AD= Distance between y coordinate of A & D OR Between B & C i.e. 13 in

Area of the Square ABCD= (length of Side AB or CD) X (Length of Side  BC or AD)

                                          = (8 x 13) \(in^{2}\)

                                          = 104 \(in^{2}\)

Given information:

The graph of computer production and advertising amount spent is given in the question.

Total number of computer sell = 40 millions

Cost of internet advertising = $5 million

Now , by looking the graph one can conclude that, Y coordinate of the graph is 40 million and the X coordinate of the graph is $5 million.

Hence, from the above conclusion one can write as:

Horizontal axis (X-axis) is the number of computers and the Vertical axis is (Y-axis) the advertising cost of computers.

I am currently 13 times as old as my granddaughter. Next year, I will be 11 times as old as my granddaughter. How old am I now?

Answers

Answer:

65 years old.

Step-by-step explanation:

Define the variables:

Let x be the age of the granddaughter.Let y be the age of the grandparent.

Given:

I am currently 13 times as old as my granddaughter. Next year, I will be 11 times as old as my granddaughter.

Create two equations with the given information and defined variables:

\(\begin{cases}y = 13x\\y + 1 = 11(x + 1)\end{cases}\)

Substitute the first equation into the second equation and solve for x:

\(\implies 13x+1=11(x+1)\)

\(\implies 13x+1=11x+11\)

\(\implies 2x=10\)

\(\implies x=5\)

Substitute the found value of x into the first equation and solve for y:

\(\implies y=13(5)\)

\(\implies y=65\)

Therefore, the age of the grandparent now is 65 years.

Given statements:

I am currently 13 times as old as my granddaughter. Next year, I will be 11 times as old as my granddaughter.

Let us represent the character's age by variables. Assuming that the grandparent's age is G and the granddaughter's age is D. Now, using the obtained variables and the statements, create two equations that represents the provided statements. Then, we can compare the equations and simplify if needed to determine the value of the variables.

    \(\implies \left[\begin{array}{ccc} \text{G = 13D} \\ \text{G + 1 = 11(D + 1)}\\\end{array}\right]\)

Since G = 13D is in the form of direct variation, we can substitute the value of G into the second equation to determine the value of D (the age of the granddaughter). Then, we can substitute the value of D into any of the two equations to determine the age of the grandparent.

⇒ G + 1 = 11(D + 1)⇒ G + 1 = 11(D + 1)                                                                      [G = 13D]⇒ 13D + 1 = 11(D + 1)

To solve for D, simplify both sides of the equation by using the distributive property. We need to simplify both sides of the equation so that we can isolate the variables on the other side of the equation.

⇒ 13D + 1 = 11(D + 1)⇒ 13D + 1 = 11D + 11

Isolate the variables on one side. This step is necessary because it can cancel out the extra variable and simplify the other variable. To do this, you can either add or subtract on both sides of the equation.

Note: I am subtracting 11D on both sides of the equation since it is my preference. But you can also subtract 13D on both sides of the equation.

⇒ 13D + 1 - 11D = 11D + 11 - 11D⇒ 1 + 2D = 11

To further isolate 2D, we need to subtract 1 on both sides of the equation to cancel out the 1 on the left-hand side of the equation. Then, we have:

⇒ 1 + 2D - 1 = 11 - 1⇒ 2D = 10

But the variable is still not completely isolated since there is a coefficient being multiplied to D. To isolate the coefficient from the variable, we will need to divide the coefficient (2) on both sides of the equation.

⇒ 2D = 10⇒ 2D/2 = 10/2

Then, simplify both sides of the equation. Eventually, we will have a variable on one side and a numerical value on the other side.

⇒ 2D/2 = 10/2⇒ D = 5

Now we know the age of the granddaughter, we can substitute the age of the granddaughter into one of the equations and simplify it to determine the age of the grandparent. I am going to choose G = 13D since it is easier to simplify. Then, we will substitute the value of D into the equation.

⇒ G = 13D ⇒ G = 13(5)⇒ G = 65 years

Therefore, the age of the grandparent is 65 years.
