given that the measurement is in centimeters, find the circumference of the circle to the nearest tenth. (use 3.14 for pi)

Answer:

Sure.

Step-by-step explanation:

So X is a variable meaning its a letter that represents a number. When there are a number and a variable (or a letter) like this 2x or 9y it means you are going to multiply the number by the variable. In this case it is 7 times x is equal to 21 so all we have to do is find what times 7 is equal to 21 and that number is 3. So if 7*x=21 is 7*3=21 then x=3. If you have any questions ill be more than open to answering them, hopefully this helped. Have a good day/night.

Answer:

The solution to the graph are x = -2 and x = 2

Step-by-step explanation:

Here, we want to get the solution to the graph

As we can see, the graph is parabolic; which is a property of a quadratic polynomial

The solution refers to the value at which the graph plot crosses the x-axis

In other words, the solutions to the graph are represented by the point at which we have the graph crossing over the x-axis

We can see this happen at two points

These are the points x = -2 and x = 2

Answer:

Alright, lets get started.

Angle 3 and angle 4 are adjacent angles because they are having the common side.

They both are on straight line, so, their addition will be 180°.

Suppose angle 4 is x , hence

angle 4 + angle 3 = 180

Subtracting 89 from both sides

°

Hence angle 4 is 91°. : Answer

Answer:

  x = 1 or 5

Step-by-step explanation:

The notion of "cross-multiplying" is the idea that the numerator on the left is multiplied by the denominator on the right, and the numerator on the right is multiplied by the denominator on the left. This looks like ...

  [tex]\displaystyle \frac{x-1}{7}=\frac{2x-2}{3x-1}\ \longrightarrow\ (x-1)(3x-1)=(7)(2x-2)[/tex]

Then the solution proceeds by eliminating parentheses, and solving the resulting quadratic equation.

  [tex]3x^2-4x+1=14x-14\\\\3x^2-18x+15=0\qquad\text{subtract $14x-14$}\\\\x^2-6x+5=0 \qquad\text{divide by 3}\\\\(x-1)(x-5)=0\qquad\text{factor}\\\\x\in\{1,5\}[/tex]

Comment on "cross multiply"

Like a lot of instructions in Algebra courses, the idea of "cross multiply" describes what the result looks like. It doesn't adequately describe how you get there. The one and only rule in solving Algebra problems is "whatever is done to one side of the equation must also be done to the other side of the equation." If you multiply one side by one thing and the other side by a different thing, you are violating this rule.

What looks like "cross multiply" is really "multiply by the product of the denominators and cancel like terms from numerator and denominator." Here's what that looks like with the intermediate steps added.

  [tex]\displaystyle \frac{x-1}{7}=\frac{2x-2}{3x-1}\\\\\frac{x-1}{7}\times7(3x-1)=\frac{2x-2}{3x-1}\times7(3x-1)\\\\(x-1)(3x-1)=(2x-2)(7)\qquad\textit{looks like}\text{ cross multiply}[/tex]

Answer:

x = 4.3

Step-by-step explanation:

Given the question :

Fill in the empty slots by dragging tiles from the left to show the next step for solving the equation. Solve the equation 1.2x = 5.16 for x X=

Taking out the equation :

1.2x = 5.16

Divudse both sides by 1.2

1.2x/1.2 = 5.16 / 1.2

x = 4.3

Hence, x = 4.3

The value of x in the equation is equal to 4.3

Data;

To solve this problem, we need to first make x the subject of formula and this is done by dividing both sides of coefficient of x.

[tex]\frac{1.2x}{1.2} = \frac{5.16}{1.2}[/tex]

This can be further simplified as

[tex]x = \frac{5.16}{1.2} = 4.3[/tex]

The value of x in the equation is equal to 4.3

Answer:

15 inches

Step-by-step explanation:

Substitute the formula

Let 'x' be the other side

2 [ l + b ] = Perimeter

2 [ 12 + x ] = 58

    12 + x   = 58 divided by 2

           x    = 27 - 12

                 = 15
