Answer: The diameter of circle is 2 yards.

Step-by-step explanation:

We know that , the circumference of a circle = \pi d ... (i), where d= diameter of circle.

Given : Circumference of circle = 6.28 yards

Put this in (i), we get

6.28=(3.14)d\ \ \ [\text{Use}\pi=3.14]\\\\\Rightarrow\ d=\dfrac{6.28}{3.14}\\\\\Rightarrow\ d=2\text{ yards}

Hence, the diameter of circle is 2 yards.

alexdok [17]

Answer:

  1. x < 2.5
  2. x > 2.5

Step-by-step explanation:

One way to do this is to try a number for x and see if it makes the inequality true. A suitable number here is x=0. This value of x is less than 2.5.

<h3>1.</h3>

For x=0, you have ...

  5 > -5 . . . . . true; the solution space is x < 2.5

__

<h3>2.</h3>

For x=0, you have ...

  -25 > -5(2.5)

  -25 > -12.5 . . . . . false; the solution space is x > 2.5

_____

<em>Alternate solution</em>

<h3>1.</h3>

Subtract 5:

  -4x > -10

Divide by -4

  x < 2.5

__

<h3>2.</h3>

Divide by -5:

  5 < x +2.5

Subtract 2.5

  2.5 < x

  x > 2.5

19 + x/2 = 4<br> How do I do this
GuDViN [60]

Answer: x = -30

Steps:  19 + x/2 = 4

Subtract 19 from both sides: 19 + x/2 - 19 = 4 - 19

Simplify: x/2 = 15

Multiply both sides by two: x/2 (2) = -15 (2)

Simplify: x = -30
