Answer:
13013
Step-by-step explanation:
Express each number in terms of the product of prime numbers.
91 = 7 × 13
143 = 11 × 13
169 = 13 × 13
Now consider the maximum number of times each factor occurs for each number.
The factor 7 occurs once
The factor 11 occurs once
The factor 13 is repeated twice ( maximum number of times for 1 number )
Thus LCM = 7 × 11 × 13 × 13 = 13013
7*(x - 7) = 126 <=>
x - 7 = 18 <=>
x = 25
80x+30
-30x-30
=50x
You subtract 30 from each side
You can divide 110 by 1 to see how many 1's go in 110:
110/1 = 110
This means that there are 110 1's in 110.
Hope this helps! :)
