Example: Set up proportions.
3/4 cups → 1 batch
x cups → 2 batches
x = 2(3/4) = 6/4 = 1 1/2 cups
3/4 cups → 1 batch
y cups → 9 batches
y = 9(3/4) = 6 3/4 cups
Answer:
D. 30
Step-by-step explanation:
-5(-8)(3)(-1) /(-4)
Lets simplify the numerator first
-5*-8 = 40
40 *3 = 120
120*-1 = -120
Replace -5(-8)(3)(-1) with -120
-120/-4
A negative divided by a negative is a positive

Answer:
a) 
, 
, 
b) 
, 
, 
Step-by-step explanation:
We can use the chain rule in the following form: is u=u(x) is a differentiable function depending on x and y=y(u) is a differentiable function depending on u, then 
.
a) 
from the power rule.
.
From the previous parts and the chain rule, 
b) 
from the power and sum rules.
Then, 
If you want to multiply 3 * 2/3, then just multiply the numerators and divide it by the denominator.
3 * 2/3
6/3 = 2
The formula of an area of trapezoid:
We have:
