Factors of 40: (1, 40) (2, 20) (4, 10) (5, 8)
---Using these factors will help us find a pair that adds up to -13 and multiplies to equal 40
-5 + -8 = -13
-5 x -8 = 40
(v - 8)(v - 5)
The trinomial can be factored into the following expression (v - 8)(v - 5).
Hope this helps!
Step-by-step explanation:
For 3 scoops = 18 cookies
Lets use the unitary method,
So for 1 scoop, how many cookies?
So, 18 /3 = 6
So, 1 scoop = 6 cookies
So for 4 scoops we will multiply by 6 (as 1 scoop = 6 cookies)
So, 4 x 6 = 24
So, 24 cookies can be made if we add 4 scoops of flour
4 scoops = 24 cookies
Answer: OPTION A
Step-by-step explanation:
Let be "a" the number of adults tickets they sold and "s" the number student of tickets they sold.
With the information given in the exercise you can set up the following System of equations:

Use the Elimination method to solve the system of equations:
1. Multiply the first equation by -6.
2. Add the equations.
3. Solve for "s" in order to find its value.
Then:

4. Finally, substitute the value of "s" into the first equation and solve for "a":
