Plz don’t skip I rlly need this answer step by step by tonight
Yuliya22 [10]

Answer:

40 quarts

Step-by-step explanation:

For this question, you set up a proportion. You know that Kelsey jarred 12 quarts of jam after 3 days so you set 12 quarts/3days equal to x quarts/10days.

12 quarts/3 days=x quarts/10 days

Then, you can cross multiply. You get 3x=120.

Then, divide 3 by both sides to get x by itself.

120/3=40

Your answer is 40 quarts.

Hope that helps!

How many days in 4 consecutive years
ella [17]
There are 365 days in a year.
So in 4 years, there are 365 × 4 = 1460 days.
However, every 4 years, there is also a "leap day." (an additional day in February of years divisible by 4 to balance the calendar)
After adding this day, we would have 1461 days in 4 consecutive years.
<em>
</em><em>*Note: There are exceptions to when leap years happen, so on some 4 year periods there is no leap year. In that case, there could be just 1460.</em>

How do you find the inverse of this function
Schach [20]

y=\dfrac{2+x}{1-\dfrac{1}{2}x}\\\\y\left(1-\dfrac{1}{2}x\right)=2+x\\\\y-\dfrac{1}{2}xy=2+x\\\\2y-xy=4+2x\\\\2x+xy=2y-4\\\\x(2+y)=2y-4\\\\x=\dfrac{2y-4}{y+2}\\\\\boxed{f^{-1}(x)=\dfrac{2x-4}{x+2}}
