It will take 6 years for that to happen.
You can find this by setting Nichole's age as x and Sophie's age as x + 28 since she will always be 28 years older.
Now we are looking for a time that Sophie's age is equal to 2 less than 6 times Nichole's age. So we can set up the below equation.
6(x) - 2 = x + 28
6x - 2 = x + 28
5x - 2 = 28
5x = 30
x = 6
This let's us know that it needs to be when Nichole is 6, which is 6 years in the future.
Answer:
6.25 litres
Step-by-step explanation:

Answer:
6x+20 or 2(3x+10)
Step-by-step explanation:
Six friends went to a basketball game and four people paid $5 extra for a t-shirt. To find the total cost, multiply 6 by x and 4 by 5 this add them together:
6*x+4*5
6x+20, If needed you can factor this expression to:
2(3x+10)
