Have three witches each holding a broom and a spoon. Witches say witch plus witch plus witch =45. Three brooms say broom plus broom plus a broom =21 and three spoons say spoon plus spoon plus spoon = 12 then final question is a plain witch plus broom x spoon equal a ? What's answer?

  32

Step-by-step explanation:

  witch plus witch plus witch = 45   ⇒   witch = 45/3 = 15

  broom plus broom plus a broom = 21   ⇒   broom = 21/3 = 7

  spoon plus spoon plus spoon = 12   ⇒   spoon = 12/3 = 4

__

If we assume each witch on first line refers to a "loaded" witch that includes a broom and a spoon, then a "plain" witch is ...

  plain witch = witch - broom - spoon = 15 -7 -4 = 4

and the final total of interest is ...

  plain witch plus broom x spoon = 4 + 7 × 4 = 4 +28 = 32

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
