Make an algebraic expression for each plan.
For an instance, x represents the number of movies, and y represents the number of months
⇒ The expression for the digital movie plan is 3x
⇒ The expression for the DVD plan is 10y + 0.5x
A person rents movies in a month (that means the value of y equals 1), the expression of the DVD plan would be 10(1) + 0.5x = 10 + 0.5x
Find the value of x when the cost of both plan are the same
The two options will cost the same when the expression for digital movie is equal to the expression for DVD
the digital movie plan = the DVD plan
3x = 10 + 0.5x
Solve for x
3x - 0.5x = 10
2.5x = 10
x = 10/2.5
x = 4
The two options will cost the same, if the person rents 4 movies
B:(5,1) where 5 is the x co-ordinate and 1 is the y co-ordinare!
Hello!
The formula for volume of a cube is
; you are given the volume, so plug it into the formula for
.
Take the cube root of each side:
![\sqrt[3]{27} = a^{3}](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B27%7D%20%3D%20a%5E%7B3%7D%20)
Answer:
The length of each side is 3 cubic feet.
Answer:
a=19.6 inches^2
Step-by-step explanation:
The area of a circle can be found using
a=πr^2
We know the radius is 2.5, so we can substitute it in for r
We can also substitute 3.14 in for π
a=(3.14)*(2.5^2)
a=(3.14)*(6.25)
a=19.625
Round to the nearest tenth
a=19.6 inches^2
What type of geometry is that...I don't remember doing any of that when i took geometry.
