Answer:6
Step-by-step explanation: first you find some factors of each number. 12- 1, 2, 3, 4, 6. 30- 1,2,3,5,6,10,15. They both have a 6 as a factor and it is the highest.
Answer:
a = 4
Step-by-step explanation:
If the variables disappear and you get a statement that is never true,such as 0=5 or 4=7 then there is no solution meaning when graphed the two equations will form parallel lines which never interact
All of the steps are good up until the 25-0, instead a 0 should have put into the top and the 1 brought down so that it was 251-248 which gets you 3 as a remainder so the answer is 804 R3
Answer:
(5-2a+6b)/2
Step-by-step explanation:
According to PEMDAS, we would multiply 2 by (a+3b) first. This would equal 2a+6b. Since this is being subtracted from 5, the numerator would equal 5-2a+6b. This would bring the simplified answer to (5-2a+6b)/2
