1) 20 stars; 30 points.

2) 28 stars, 42 points.

3) 38 stars, 57 points.

Step-by-step explanation:

Let  be "x" the numbers of stars Roberto collects and "y" his total points.

The proportional relationship has this form:

Where "k" is the constant of proportionality.

We can choose the point ) from the table, where:

Substituting these values into   and solving for "k", we get:

Knowing the value of "k", we determine that the  following Numbers of stars and the Total points could be used as the missing values in the table:

1) For :

2) For :

3) For :

8y^50

step-by-step explanation:

55 degrees because 55+55=110 degrees
