Answer:
Step-by-step explanation:
mean is average, so if we label the first through fifth days of january a-e we can solve it.
So average of the first four is (a+b+c+d)/4 = 1 and the first five is (a+b+c+d+e)/5 = 2. Since it's easy, let's get rid of the fraction in both.
(a+b+c+d)/4 = 1 and (a+b+c+d+e)/5 = 2
a+b+c+d = 4 and a+b+c+d+e = 10
Now, we know a+b+c+d is 4, so we can replace that in the second equation
a+b+c+d+e = 10
4 + e = 10
e = 6
ad since e is the fifth day, we know the temperature of it. Let me know if something here didn't make sense

Step-by-step explanation:
We can look at the fractions 
and 
and add them up.
Looking at the whole numbers, 
.
Looking at the fractional parts, 
.
So all together, she currently has 
yards.
If she wants to get to 10, we need to find how many more yards we need.
Let's level it out quickly - having 
more of a yard will give is 6 yards.
, so in total we added
more yards.
So she needs more yards.
Hope this helped!
