Nancy and kevin collect coins. nancy has x coins. kevin has 4 coins fewer than two times the number of coins nancy has. write and simplify an expression for the total number of coins nancy and kevin have.

total: 3x + 4

Step-by-step explanation:

Nancy = x

Kevin = 2x+4

together = 3x + 4

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

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
