If the diameter of a circle is 25 inches, what is the radius of the circle?
sergij07 [2.7K]
Hello there, and thank you for posting your question here on brainly.

The diameter of a circle is how long it is from the left side of the circle to the right side.

The radius of a circle is the length of either the left or the right side to the middle.

So, the radius is half of a radius.

You can divide the known diameter by 2 to get your answer.

Its diameter is 25.

Divide 25 by 2.

25 / 2 = 12.5

Its radius is 12.5 in.

That would be answer choice A.

Hope this helped!! ☺♥

Solve this system by elimination <br> 10x+6y=14<br> -x-6y=-23
ludmilkaskok [199]

Answer:

(-1, 4)

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define systems</u>

10x + 6y = 14

-x - 6y = -23

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Elimination</em>

  1. Add 2 equations together:                    9x = -9
  2. Divide 9 on both sides:                          x = -1

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define original equation:                    -x - 6y = -23
  2. Substitute in <em>x</em>:                                     -(-1) - 6y = -23
  3. Multiply:                                                1 - 6y = -23
  4. Subtract 1 on both sides:                     -6y = -24
  5. Divide -6 on both sides:                      y = 4

Please answer what the answer for ? Is.
vitfil [10]

Answer:

5/8

Step-by-step explanation:

A.   2/3 × 4/5 × m = 1/3               B.      4/5 × 2/3 × m = 1/3

      8/15 × m = 1/3                                 8/ 15 × m  = 1/3                                    

                 m = 1/3 ÷ 8/15                                 m = 1/3 ÷ 8/15

                  m = 1/3 ×15/8                                 m = 1/3  × 15/8

                  m = 5/8                                          m = 5/8        

C.  2/3 × 4/5 = 1/3 ÷ m        

            8/15 =  1/3 ×  1/m

            8/15 = 1/3m                   cross multiply  

           (3m) × (8) = 15

                24m = 15

                     m = 15/24

                     m=  5/8
