Answer:
6 movies
Step-by-step explanation:
45-30=15 spent on movies
divide the 15 by 2.5 to get 6.
$30+$2.50m=$45
where m is the amount of movies
Answer:
let he purchaseed x movies
30 + 2.5x = 45
or 2.5x = 15
x=15/2.5 =6
Step-by-step explanation:
The discriminant is equal to −16, which means the equation has two real number solutions.
The discriminant is equal to 24, which means the equation has no real number solutions.
The discriminant is equal to 24, which means the equation has two real number solutions.
The correct option regarding the discriminant of the quadratic equation is given by:
The discriminant is equal to −16, which means the equation has no real number solutions.
A quadratic equation is modeled by:
The discriminant is:
The solutions are as follows:
In this problem, we have that:
5x² - 2x = -1
5x² - 2x + 1 = 0
Hence the coefficients are a = 5, b = -2 and c = 1, while the discriminant is given by:
No real solutions, hence the first option is correct.

Find the area. Answer without units.'
7 ft
8 ft.
Answer:
A = l*w
A= 7*8
A= 56
56 is the area
(n + 8)(n - 2)
n^2-n*2+8n-16
n^2-2n+8n-16
=n^2+6n-16
Which statement best describes how much of each ingredient Paul needs to measure?
A.Paul should measure exactly 4 cups of flour and 1 cup of brown sugar since that makes a total of 5 cups of ingredients.
B.Paul should measure exactly 4.5 cups of flour and 0.5 cup of brown sugar so that he has enough flour and not too much brown sugar for the recipe.
C.Paul should make it easy and just measure a total of 5 cups of flour and brown sugar since it all gets mixed up in the recipe anyway.
