Find the diameter of a circle if its circumference is 53.38 inches. Use π ≈ 3.14. Round to the nearest hundredth

Answers

Answer:16.9

Step-by-step explanation:

We know that the formula for C= πd. So to find the diameter of a circle we work backwards from its circumference. Division is the opposite of multiplying, so we divide its circumference by π: 53.38 / 3.14 = 17. To fully check: C= πd = π(17) = 53.38. The diameter is 17 inches. Hope this helps!

HELP MEH Please write the coordinates of the x-intercept: y = 500

Answers

Well, there needs to be an equation.

Answer:

See explanation

Step-by-step explanation:

The x- intercept is where the line crosses the x- axis. Let y = 0 in the equation and solve for x

5(0) = 2x - 1, that is

0 = 2x - 1 ( add 1 to both sides )

1 = 2x ( divide both sides by 2 )

The x- intercept is ( , 0 )

The y- intercept is where the line crosses the y- axis. Let x = 0 in the equation and solve for y

5y = 2(0) - 1

5y = - 1 ( divide both sides by 5 )

y = -

The y- intercept is (0, -  )

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:

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.

How is solving a two-step equation similar to solving a one-step equation?

Answers

Answer:

Because it is the same concept, now u have to do more work.

For example

1+1 would be a one step equation

and

1+1(5) would be a two step equation

it's just a bit more.

Each step in solving an equation is like solving a one-step equation so solving a two-step equation is similar to solving a one-step equation

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 9 is an equation

We have,

Two steps equation.

Example:

2 + 3 - (3 x 4)

Step 1:

2 + 3 - 12

Step 2:

5 - 12

-7

One-step equation.

Example:

2 + 4

Step 1:

2 + 4

6

We see that,

Solving a two-step equation is similar to solving a one-step equation because, in the two-step equation, each of the two steps is like one step individually.

Thus,

Solving a two-step equation is similar to solving a one-step equation.
