Justin, Nadine, and Mark were competing to see who could score the most points in their basketball game. Nadine scored five points more than Mark. Write an algebraic expression to represent the number of points Nadine scored,

• Nadine's points can be represented as 5m + j where m is Mark and j is Justin

• Nadine points can be represented by m + 5 where m represents mark

• Nadine points can be represented by n + 5 where j represents Justin

James said the factors of the expression: 5 · (8 – a) are 5, 8 and a

• False, factors are numbers or variables that are multiplied and 5, 8 and a are not all being multiplied together

• False a is a variable and only numbers can be multiplied together not variables

• True, everything is a factor because everything is being multiplied together

• Yes, the only coefficient is 15

• No, 15 is a coefficient as well as the 1 or -1 that is understood to be next to the variable x

• No 8 is the coefficient

Jennifer was asked to rewrite each of the following expressions in word form, using the words sum, product, difference, and quotient as needed. What should she have written for the following expression 20(y-3)

• y minus 3 times 20

• The product is 60 because of the 1 understood to be next to the y

• 20 times the difference of y and 3

• 5 plus x over 9

• Turn thee 5 into a fraction by putting it over one then you would find the sum and add

• 5 plus the quotient of x and 9

• 5 plus x divided by 9
