The answer I she had 3 carrots, this I how you solve it
15* 1/5
I do not know how to upload the drawing so sorry about that!
Answer:
1. 2x + 3y = 240 AND x + y = 100
Nayeli sold 60 cups of lemonade and 40 cups of orange juice.
Step-by-step explanation:
Let
Number of cups of lemonade sold = x
Number of cups of orange juice sold = y
The system of equation could be represented by:
2x + 3y = 240 (1)
x + y = 100 (2)
from (2)
x = 100 - y
Substitute into (1)
2x + 3y = 240 (1)
2(100 - y) + 3y = 240
200 - 2y + 3y = 240
- 2y + 3y = 240 - 200
y = 40 cups
Substitute y = 40 into (2)
x + y = 100 (2)
x + 40 = 100
x = 100 - 40
x = 60 cups
Nayeli sold 60 cups of lemonade and 40 cups of orange juice.
(x, y) = (60, 40)

Step-by-step explanation:

Answer: -2, 0, 4
Set the equation equal to zero.
x³ - 2x² - 8x = 0
Factor out x in the equation, since all the terms (x³, -2x², and -8x) are divisible by x. You can check your accuracy using the Distributive Property.
x(x² - 2x - 8) = 0
Factor out the polynomial. To do this, find two numbers that multiply to get the last term, -8, and add together to get the middle term, -2. In this case, those two numbers are -4 and 2 (-4 × 2 = -8 and -4 + 2 = -2). Don't forget about the x that was factored out before!
x(x - 4)(x + 2) = 0
Set each factor equal to zero and solve for x. The factors in the equation are x, (x - 4), and (x + 2).
x = 4
x = -2
The zeros of the polynomial function are -2, 0, and 4.
47% of 13,500 is 6,345. So this years sales would be $19,845.
