Answer:
The greatest common factor of 42, 60 and 78 is 6.
Step-by-step explanation:
The given numbers are : 42, 60 and 78
On Prime Factorization of the given terms, we get:
42 = 2 x 3 x 7
60 = 2 x 2 x 3 x 5
78 = 2 x 3 x 13
The common factors to all these three terms is 2 x 3 = 6
Hence, the greatest common factor of 42, 60 and 78 is 6.
Answer:

Answer:
73
Step-by-step explanation:
let the number = X
If 139 is added, it becomes= X +139
the result becomes 44less than four time the number
= 4(39)-44 = 156-44 =112
the set up equation becomes
X +39 = 112
solving for the value of X
X = 112-39
X = 73
Answer:
10 > 2.01
Step-by-step explanation:
Since 2.01 has a point of decimal after the # 2, it is known is a 2 so 10 should be greater than the 2.
