Answer:

Number of goblins = 120

Step-by-step explanation:

Let number of goblins in the magic club be x

Number of goblins and wizards all together in the magic club are given to be 220

⇒ Number of wizards in the magic club be 220 - x

Now, according to the condition given in the problem

⇒ Number of goblins = Number of wizards + 20% of number of wizards

⇒ x = 220 - x + 20% of (220 - x)

⇒ x = 220 - x + 0.2·(220 - x)

⇒ 2·x = 220 + 44 - 0.2·x

⇒ 2.2·x = 264

⇒ x = 120

PLZ SOMEONE HELP ME AND EXPLAIN <br> THX

The graph of g is one-fifth as steep as the graph of f.

The function g basically takes the inputs for f and multiplies them by one-fifth, which means the outputs are one-fifth times those of f. Multiplying by one-fifth makes something smaller (it's the same as dividing by five). It helps to visualize this relationship, so I've attache the graphs below.

What is the solutions to the equation w/2w-3=4/w
labwork [276]

Answer:

{2, 6}

Step-by-step explanation:

w/2w-3=4/w  is ambiguous.  Did you mean

   w            4

---------- = ------     ?  If so, please enclose "2w - 3" inside parentheses.

2w - 3       w

Cross multiplying, we get w² = 8w - 12.

Putting this into standard form, we get:

w² - 8w + 12 = 0, which factors into (w - 2)(w - 6) = 0.

The solutions are found by setting each factor = 0 separately and solving the resulting equations for w:  {2, 6}.
