Answer:
12 liters of water should be added to the current mixture to obtain a new mixture containing milk and water in a 1:1 ratio.
Step-by-step explanation:
solve this problem, we can follow these steps: Step 1: Determine the current amounts of milk and water in the mixture. The ratio of milk to water in the current mixture is 2:1. Since there are 36 liters of the mixture in total, we can calculate the amounts of milk and water as follows: Amount of milk = (2/3) * 36 = 24 liters Amount of water = (1/3) * 36 = 12 liters Step 2: Determine the new total volume of the mixture. To achieve a 1:1 ratio of milk to water, the total volume of the new mixture will be the sum of the amounts of milk and water, which is 24 + 12 = 36 liters. Step 3: Determine the amount of water to be added. Since we want the ratio of milk to water to be 1:1, the amount of milk and water in the new mixture will be equal. Therefore, we need to add an additional 12 liters of water to the current mixture.
Answer:
$60
Step-by-step explanation:
Method 1
We want to know how much money Roman originally has considering if he spends $15, then he has of the original amount left. So,
We know that = 15 so = 30 and double that will get 60 so 60 is the original amount
Method 2
Lets call the original amount 'x'
If he spends $15 he has of the original amount so,
x = 15
In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we divided 15 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.
x = 15
→ Multiply both sides by 4 to isolate x
x = 60
So $60 was the original amount

Answer:
-4ab.
Step-by-step explanation:
If the temperature is -2 degrees and it goes down another 2 degrees the new temperature is -2-2 = -4.
-2ab - 2ab = -4ab.
Answer:
-4ab because if you have a balance of negative two dollars and you spend two more dollars you have a balance of negative 4 dollars
