24 Blue marbles.

Explanation:

56 - 8 = 48

48 / 2 = 24

so if there are 24 blue marbles, 24 x 2 = 48, and then 8 more is 56.

Answer:

40

Step-by-step explanation:

b + r = 56 (1)

b = 2r + 8 (2)

(1) r = 56 - b

(2) b = 2(56 - b) + 8

b = 112 - 2b + 8

3b = 120

b = 120÷3

b = 40

A) Every T is worth 7 points, and every F is worth 3 points.  So if we let T = 7 and F = 3, we can count how many T's and F's each team scored and write it as an expression.


So for the East Side Bulldogs, they have 7 touchdowns and 6 field goals, thus the expression for them is:

7T + 6F

For the West Side Bulldogs, they have 5 touchdowns and 5 field goals, thus the expression for them is:

5T + 5F

B) The difference would be written as:
7T + 6F - (5T + 5F) = 2T + F

C) To determine how many more points the winning team has than the losing team, calculate the scores of the two teams.  Then subtract the smaller number from the larger number to determine the score differential.
