Answer:
3 months
Step-by-step explanation:
Let x be the number of months CDs are added at Tom and Nita's respective rates of 1 and 5 CDs/month.
Tom's collection after x months is = 30 + 1x
Nita's collection after x months is = 18 + 5x
At some point they will have equal numbers of CD's, so set the equations equal to each other:
30 + 1x = 18 + 5x
4x = 12
x = 3 months
At 3 months both Tom and Nita will have the same number of CDs.
Tom: 30 + 1*3 = 33 CDs
Nita: 18 + 5*3 = 33 CDs
Answer:
3x + 2 = 50
16
Step-by-step explanation:
According to the given situation, the equation to determine the number of friends is shown below:-
We assume the number of friends is x
50 - 3x = 2
-3x = -48
3x = 48
x = 16
So, the equation is
3x + 2 = 50
and the number of friends is 16
Therefore, the equation to determine the number of friends we just solved the above equation.
9514 1404 393
Answer:
The correct answer choice is marked
Step-by-step explanation:
The distributive property can be used here.
It would be 3 1/3 because you multiply the side lengths of the first triangle to get the second. Hope this helps:)
