Step-by-step explanation:
Step-by-step explanation:
Below is an attachment containing the solution.
Let the number of marbles be M,
then,
M=6a+4 (when shared among 6 students)
M=7b+4 (when shared among 7 students)
M=8a+4 (when shared among 8 students)
thus
M-4=6a
M-4=7b
M-4=8c
That is M-4 is the smallest number which is a multiple of 6, 7 and 8
Thus we need to find the LCM(6, 7, 8)
LCM(6, 7, 8)=LCM(2*3, 7, 2*2*2) = 2*2*2*3*7=8*21=168
The smallest M-4 is 168,
so the smallest M is 168+4=172
Answer: 172
Answer:
14x+3
Step-by-step explanation:
The given expression is as follows :
4x + 3(2x +1) + 4x
We need to find the equivalent expression for the above.
So,
4x + 6x +3 + 4x
Adding x terms,
14x+3
Hence, the correct equivalent expression is 14x+3.
First we must add 3y to both sides and we are left with 14 = 7y. Then we divide by 7 leaving y = 2
