Answer:
Cannot simplify the fractions further than that
Step-by-step explanation:
The fractions 5/8 and 3/10 have already been simplified so they do not need to be simplified anymore. If you are wanting to put them in decimal form then that is different. All you have to do is plug it in the calculator.
Answer:
Therefore he should sell 25 units of tacos to minimize his cost .
The minimum cost is $240.
Step-by-step explanation:
Given function,
where C is the cost in dollar to sell x units of tacos.
We know that,
If a function y(x)= ax²+bx+c,
then the function is minimum at 
Here a= 1 , b= -50 and c= 865.
Therefore
Therefore he should sell 25 units of tacos to minimize his cost .
putting the value of x in the given function
C(25)=25²-(50×25)+865
=240
The minimum cost is $240.
Answer:
If we solve this equation for y, it is equal to 18 - b
Step-by-step explanation:
To find this, we start with the original.
18 = y + b
Now we subtract b from both sides.
18 - b = y
B.
So when you solve the system of equations you get that y=14 and x=10. When you plug those into the original equations you get true statements.
The equation which is used to model this function is y = 25x.
<h3>What is equation?</h3>
An equation is a mathematical expression that contains an equals symbol. Equations often contain algebra.
Given:
x=2 , y=50
x=4, y=100
As, corresponding to x =2 , y =50
For x=1 , y=25
Hence, the equation which is used to model this function is y = 25x.
