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
He needs to save $22 more.
Let x be the number of times Frankie will need to babysit.
Thus, we can write the equation:
Thus, Frankie will need to babysit for 4.4 time.

Answer: there are eight bicycles and 7 tricycles.
Step-by-step explanation:
Let x represent the number of bicycles that are there.
Let y represent the number of tricycles that are there.
There are a total of 15 bicycles and tricycles. This means that
x + y = 15
A bicycle has 2 wheels and a tricycle has 3 wheels. There are 37 wheels all together if we count them up. This means that
2x + 3y = 37- - - - - - - - - - - - - 1
Substituting x = 15 - y into equation 1, it becomes
2(15 - y) + 3y = 37
30 - 2y + 3y = 37
- 2y + 3y = 37 - 30
y = 7
x = 15 - y = 15 - 7
x = 8
