Answer:
total: 3x + 4
Step-by-step explanation:
Nancy = x
Kevin = 2x+4
together = 3x + 4
Answer:
The expression for the total number of coins owned by both Nancy and Kelvin is
= x + 2x - 4
= 3x - 4
Step-by-step explanation:
The relationship between the number of coins collected by each person is given in the statement "Nancy has x coins. Kevin has 4 coins fewer than two times the number of coins Nancy has."
Number of Nancy's coins = x
Since Kevin has 4 coins fewer than two times the number of coins Nancy has
Number of Kelvin's coins = 2x - 4 = 2(x-2)
Hence the expression for the total number of coins Nancy and Kelvin have
=x + 2x - 4
= 3x - 4
