Sarah drinks 30 liters of water on weekdays and 12 liters of water on weekends. How many liters of water does Sarah drink per day?

Easy, 6

30 divided by 5 equals 6

12 divided by 2 equals 6

6 liters per day

Step-by-step explanation:

Hi there!

We know that Sarah drinks 30 liters on weekdays. There are 5 days in a week not including the weekends. You have to divide 30 liters by 5 to get the per day amount. 30 divided by 5 is 6. This means that Sarah drinks 6 liters per day. This is accurate because when you go on to check the amount of water she drinks on weekends, you know there are two days in a weekend, and you know she drinks a total of 12 liters during the weekend, so 6 liters multiplied by those two days is equal to 12.

Really hope this helps :)

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
