Answer: she played 5 games and went on 8 rides
Step-by-step explanation:
Let x represent the number of games that Sydney played.
Let y represent the number of rides that Sydney went on.
Each game cost $1.25 and each ride cost $2.25. If Sydney spent $24.25 altogether at the carnival, then the expression is
1.25x + 2.25y = 24.25- - - - - - - - - - -1
If the number of rides that she went on is 3 more than the number of games that she played, the expression would be
y = x + 3
Substituting y = x + 3 into equation 1, it becomes
1.25x + 2.25(x + 3) = 24.25
1.25x + 2.25x + 6.75 = 24.25
3.5x = 24.25 - 6.75
3.5x = 17.5
x = 17.5/3.5
x = 5
y = x + 3 = 5 + 3
y = 8

Answer:
8
Step-by-step explanation:
The greatest common divisor or highest common factor can be found by considering the factors of the 3 numbers
factors of 8 are 1, 2, 4, 8
factors of 16 are 1, 2, 4, 8, 16
factors of 24 are 1, 2, 3, 4, 6, 8, 12, 24
The common factors are 1, 2, 4, 8
the greatest common factor is 8
Thus the greatest common divisor of 8, 16 and 24 is 8
