So, in order to find the answer, this is what we are going to do.
Let K be the number of candies that Kahi can eat per hour and S be the number of candies that her sisters can eat per hour.
So for the sisters, let us divide 32 by 3 and we get, 10.67. so 10.67/ hour.
Now, consider this expression: <span>(K+S)*h = 32
Plug in the given values.
(32 +10.67)h = 32
42.67h = 32
Divide both sides by 42.67 and we get
h= 1.33. Therefore, it will take 1.33 hour for both of them together to eat 32 candies. Hope this answer helps.</span>
Answer:
y = -4
Step-by-step explanation:
Combine the y terms. To do this, add 0.3y to both sides, which results in:
5.1y + 0.3y = -21.6, or
5.4y = -21.6
Dividing both sides by 5.4 yields the desired result:
y = -21.6/5.4 = -4
X² - 3x - 4 = 0
Reverse FOIL method . . .
(x - 4)(x + 1) = 0
one of the paranthesis has to be equal to zero if the other is not . . .
x - 4 = 0
<u><em>x = 4</em></u>
x + 1 = 0
<u><em>x = -1</em></u>
