Answer:
1 2/21
Step-by-step explanation:
We start out with:
3/7 + 2/3
In order to add them together, they must have an equal denominator. An easy way to find an equal denominator is the cross method. We divide 7 by 3 and 3 by 7, giving us a denominator of 21:
3/21 + 2/21
But what about the numerators? You do the same thing as before (multiplying by the other's denominator). Now we have:
9/21 + 14/21
We add both together (the denominator stays the same) and we get 23. 23/21 is correct but not in simplest form. We remove 21 from the numerator (because it is a whole) and finally get:
1 2/21!

Answer:
30 degrees
Step-by-step explanation:
the line (not at the 0) is what you measure from. Because the angle is visibly acute, we know that it must be less than 90 degrees, therefore the angle cannot be 150 degrees but 30 degrees (from the lower line)
Answer:
1300
Step-by-step explanation:
We are given
x = 35
[rate of change of price with time]
We want to find 
, which is the rate at which supply is changing.
First, we need to implicitly differentiate the equation given:
Here, we have what we need except for p. We find p when x = 35:
Now, find dx/dt:
In thousands, 1.30 * 1000 = 1300 cartons per week decrease
