Step-by-step explanation:
Let n be the number of nickels that Casey has.
We are told that Megan has 4 times as many nickels as Casey has, therefore, the number of nickels that Megan has will be 4*n.
Now we will add the amounts of nickels that Casey and Megan have to find the total amount of nickels.

Therefore, the expression
will represent the total number of nickels that Casey and Megan have .
Upon combining like terms we will get,


Therefore, Casey and Megan have 5n nickels.
Answer:
I think the answer is D
Step-by-step explanation:
Step-by-step explanation:
you must do by unitary methods, first find smaller quantity and then multiply with remaining one.
I think it would be easiest to solve for x in this system of equations if you did so by elimination:
Start by finding the least common multiple of 3 and 2 to make the Ys cancel:
4x-6y=-54
-9x+6y=69
_________
-5x=15
x=-3 - answer B
The point slope equation would be one of the equations with -10 in front because it multiplies into x as the negative 10 slope. That narrows it down to C and D. Then the points show 1 and 4 and it has to be positive. That narrows it down the answer D. If this is right could you possibly give me brainliest? Hope this helped.
