2.396 liters
239.6 liters

23,960 liters

Answers

2.396 which is also a.

Answer:

2.396

Step-by-step explanation:

The units of measurement go like this:

Kilo, hecto, deca, unit, deci, centi, mili

When you move to the right, you move the decimal one place to the right, and when you move left, you move the decimal one place to the right

If you’re changing milliliters to liters (unit), you have to more the decimal 3 times to the left. This makes it 2.396 liters

Devon became a waiter at a fancy restaurant. He makes $9 per hour. One night he made $150 in tips. How many hours did he work if he made a total of $226.50.

Answers

Answer:

9x + 150 = 226.50

Step-by-step explanation:

Devon makes $9 per hour. So, that signalizes "9x" (x representing the amount of hours he worked)

$150 represents how much he made one night, so you would add that to 9x. (9x + 150)

Finally, it gives you the total amount: 226.50

In conclusion, your equation should be: 9x + 150 = 226.50

226.50 is the answer for your question
