Choose all the problems that can be solved with 54:6= 0. A. Dave has 6 Jars. Each jar has 54 crayons in it. How many crayons does he have in all?
B. Dave has 54 crayons. He puts some in a jar. He has 6 crayons left. How many did he put in the jar?
C. Dave has 54 crayons. He wants to put the same number of crayons in 6 jars. How many crayons go in each far?
D. Dave has 6 jars and 54 crayons. He puts the same number of crayons in each jar. How many crayons does he put in each Jar?

The only number less than 8 that can equal 12 would be 6, 36 is the dividend

Ok here we go ..there are plenty of ways to solve such math problems but we will go for the smartest and easiest ..5x+2y=7  -2x+6y=9we rearrange them into the following ..by multiplying the 1st equation by 2 it becomes 10x + 4y = 14we rearrange it and so it becomes 10x = 14 - 4yas for the second equation we multiply it by 5 and rearrange it so it becomes as to the following ..-10x + 30y = 45rearranging so 10x = 30y -45now 10x equals both 14 - 4y and 30y -45so   14 - 4y = 30y -4531 = 26yy= 31/26 = 1.19 or around 1.2so by now we can calculate x easily as  -2x+6y=9so 2x = 6y -9 = 6 * 31/26 - 9 = -1.84  then x = - 0.92 or around -0.9best luck!
