Answer:

73

Step-by-step explanation:

the first thing we should work on is wands. 21/3=7 so 1 wand = 7. Then we do the brooms, count them there are 4. so 12/4=3 so 1 broom = 3. Next we do the witches, (witch + wand + broom) * 3 = 45 so you divide both sides by 3 to simplify into witch + wand + broom = 15, plug in the known values, witch + 7 + 3 = 15, solve for witch: witch = 5. so finally we have (broom = 3) + (witch = 5) * (2*wand = 14), order of ops says we do multiplication before addition so the final equation is 3+(5*14)=73

Answer:

  73

Step-by-step explanation:

Three relations are given for the three icons. We are asked for the value of another specific relation.

setup

The first relation shows 3 instances of (witch + wand + broom) = 45.

The second relation shows 3 instances of wand = 21.

The third relation shows 4 instances of broom = 12. (The "fuzzy" broom is apparently 2 instances of broom stacked together.)

__

solution

We can solve the last two relations to get ...

  wand = 21/3 = 7

  broom = 12/4 = 3

Then the first relation becomes ...

  3(witch + 7 + 3) = 45

  witch +10 = 15 . . . . . . . divide by 3

  witch = 5 . . . . . . . . . subtract 10

__

Apparently the "fuzzy" wand in the final expression is intended to represent 2 wands. Then the desired expression is ...

  broom + (witch × 2 × wand) = 3 +(5×2×7) = 3 +70 = 73

The value of the final expression is 73.
