Lily and rose are playing a game, in the game,each player starts with 0 points and the player with the most points at the end win.

Lily gains 5 points two times loses 12 points ,and then gains 3 points.

Rose loses 3 points two times,loses 1point,gains6 points another gains7 points

A write and evaluate an expression to find Lily's score

B write and evaluate an expression to find roses score

C who won the game?

Answer 1

A.
Lily's score = 5*2 - 12 + 3
Order of operations says to do multiplication before addition and subtraction, so this evaluates to:
10 - 12 + 3 = -2 + 3 = 1

B.
Rose's score: -3*2 - 1 + 6 + 7
Again, multiplication is evaluated first, so this becomes:
-6 -1 + 6 + 7 = -7 + 6 + 7 = 6

C. Rose wins because 6 is greater than 1.

Answer 2

8 less than the product of 5 and -4

Answer 3

8 less than the product of 5 and -4 would be....

First:5x(-4)=20

Then: 20×8= 160

Answer 4

A.
Lily's score = 5*2 - 12 + 3
Order of operations says to do multiplication before addition and subtraction, so this evaluates to:
10 - 12 + 3 = -2 + 3 = 1

B.
Rose's score: -3*2 - 1 + 6 + 7
Again, multiplication is evaluated first, so this becomes:
-6 -1 + 6 + 7 = -7 + 6 + 7 = 6

C. Rose wins because 6 is greater than 1.
