Answer:
225 milliliters
Step-by-step explanation:
Marianne tried to drink a slushy as fast as she could. She drank the slushy at a rate of 4.5 milliliters per second. After 17 seconds 148 5 milliliters of slushy remains. how much slushy was originally in the cup?
let x = slushy originally in the cup
total slushy consumed in 17 seconds = 17 x 4.5 = 76.5 ml
x - 76.5 = 148.5
collect like terms
x = 148.5 + 76.5
x = 225 ml
Answer:
i think its 1.2 not too sure though
Step-by-step explanation:
Answer: C (21)
Step-by-step explanation:
I am translating into algebra.
Set Scott's age five years ago to: x
Set Paul's age five years ago to: 2x-4
Scott's age now is his age five years ago, plus five, which is: x+5
Paul's age now is his age five years ago, plus five, which is: 2x-4+5 or 2x+1
Since Paul is now six years older than Scott, set Scott's age (x+5) equal to Paul's age, plus six, which is: 2x+1=x+5+6
Solve the equation to get: x=10
Substitute x for 10 in Paul's current age: 2*10+1=21.
Therefore, C is the correct answer.
Answer:
x = -6
Step-by-step explanation:
-11x - 30 + 6x = 0
-11x + 6x -30 = 0
-5x - 30 = 0
-5x = 30
-x = 30/5
x = -6
