A basketball team scored points by making baskets worth different numbers of points during a game.

• The team made 6 baskets worth 3 points each.

• The team made 21 baskets worth 2 points each.

• The team scored 16 points by making baskets worth 1 point each.

This equation can be used to find p, the total number of points the basketball team scored during the game. p = 6(3) + 21(2) + 16 What is the total number of points the basketball team scored during the game?

Elsa and a group of her friends always sit together at lunch. Every day students join them at the table where they sit. The table below shows the relationship between the number of students joining Elsa and her friends and the total number of students sitting at the table.

The type of relationship that exists between the number of students joining and the total number of students at the table is —

• an additive relationship, because the pattern is to add 5 to the number of students joining in order to get the total number of students at the table

• a multiplicative relationship, because the total number of students at the table is greater than the number of students joining

• an additive relationship, because the number of students joining is less than the total number of students at the table

• a multiplicative relationship, because the pattern is to multiply the number of students joining by 5 in order to get the total number of students at the table

The figure shows the base layer of a rectangular prism that Sophie built using blocks.

• The prism was made by stacking 10 layers of the blocks.

• Each layer was identical to the base layer.

• Each block has a volume of 1 cubic unit.

• 150 cubic units

• 40 cubic units

• 180 cubic units

• 300 cubic units

Which answer choice best describes the x-coordinate in an ordered pair?

• The horizontal line composed of the set of points that all have a y-coordinate of 0

• The first number in an ordered pair that determines the movement left or right from the origin on a coordinate grid

• The second number in an ordered pair that determines the movement up or down from the origin on a coordinate grid

• The intersection of two lines on a coordinate grid
