Answer:

Frankie will need to babysit for 4.4 time.

Step-by-step explanation:

We are given the following in the question:

Money earned by Frankie each times he babysits = $5

Money saved = $30

Total money Frankie wants to save for a skateboard = $52

Amount of money to be saved =

Total amount of money Frankie wants to save for a skateboard - Money saved already

$= 52-30\\=22\$$

He needs to save $22 more.

Let x be the number of times Frankie will need to babysit.

Thus, we can write the equation:

$5x = 22\\\\\Rightarrow x = \dfrac{22}{5}\\\\\Rightarrow x = 4.4$

Thus, Frankie will need to babysit for 4.4 time.

Simplify this problem please

Nookie1986 [14]

First work out the parenthesis:

9x⁴y⁴ / 3y²

Then get rid of the denominator using 9/3=3 and y⁴/y² = y²

3x⁴y² is the simplest form.
