Answer:
its 12
Step-by-step explanation:
LCM of 3,4 and 6 is 12
no it is not simplified because there are two y values
Step-by-step explanation:
6k + 12 + 9=9
6k + 12 = 9 - 9
6k + 12 = 0
12 = -6k
12/-6 = -6k/-6
2/-1 = k
k = -2
2(10+5)−5
=(2)(15)−5
=30−5
=25
C is the answer.
the answer would be 33. so the first thing you want to do is turn 7 feet into inches. if 12 inches is equal to 1 foot then 7 feet are equal to 84 inches. then add another 84 inches which will equal 168. the you would want to divide 168/15 which gives you 33.6. this mean that 33 (separate numbers) 15 inches of board from two boards.
hope I was able to help and that my explanation made sense. : )
