Step-by-step explanation:

Answer: D(x) = 2kg/h*x
where x is the number of hours.
Step-by-step explanation:
The information that we have is:
in 5 hours, we can prepare 10kg of dough.
With this, we can find the rate per hour, to do this we find the quotient:
R = 10kg/5h = 2kh/h
This meeans that in one hour, we can make 2kg of dough.
Then, in x hours, we can make x times 2kg of dough, then the equation will be:
D(x) = 2kg/h*x
where x is the number of hours.
Answer:
1/4 is the number
a.k.a. 0.25
Step-by-step explanation:
Replace the words "a number" with x
4x + 2 = 3
Then, simplify
4x = 1
x = 1/4
Area of circle= 3.14r^2
r= 4
A= 50.27
