Answer:
6
Step-by-step explanation:
The factors of 24 are : 1, 2, 3, 4, 6, 8, 12, 24
The factors of 30 are : 1, 2, 3, 5, 6, 10, 15, 30
The common factors are 1, 2, 3, 6
The greatest common factor is 6
graph Q shows that. it starts at y intercept 2 and goes down by 1
a = 25 , b = 14
For A
a/5 + 3 = 8
a/5 = 8 - 3
a/5 = 5
Cross multiply
a = 5 * 5
a = 25
For B
3b/7 - 1 = 5
3b/7 = 5 + 1
3b/7 = 6
3b = 42
b = 42 / 3
b = 14
Hope it will help
