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?
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.
8 less than the product of 5 and -4 would be....
First:5x(-4)=20
Then: 20×8= 160
To find Lily's score, we can write an expression based on the given information.
Let's break down the points gained and lost by Lily:
Lily gains 5 points two times: 5 + 5 = 10
Lily loses 12 points: - 12
Lily gains 3 points: + 3
Now, we can write an expression to find Lily's score:
Lily's score = 0 + 10 - 12 + 3
Lily's score = 1
So, Lily's score is 1.
Similarly, to find Rose's score:
Rose loses 3 points two times: -3 - 3 = -6
Rose loses 1 point: -1
Rose gains 6 points: +6
Rose gains 7 points: +7
Now, we can write an expression to find Rose's score:
Rose's score = 0 - 6 - 1 + 6 + 7
Rose's score = 6
So, Rose's score is 6.
Since both Lily and Rose have positive scores, we need to compare them to determine who won the game.
Since Lily's score is 1 and Rose's score is 6, Rose has the higher score. Therefore, Rose won the game.
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.
