Answer:
$23.00
Step-by-step explanation:
The tip amount is $3.00, but the total is $23.00
rewrite the equation set = to 0.
x^2 + 5x - 8 = 0
The quadratic will not factor so you have to use the quadratic formula.
x = (-b + - sqrt(b^2 - 4ac))/2a
x = (5 + - sqrt(25 - 4* 1* -8))/2
x = (5 + - sqrt 57)/2
The x2is not the same as 2x. It is x^2. X tot he second power which makes the problem a quadratic equation. You cannot combine the terms x^2 and -5x because they so not have the same power.

Answer:
7 1/5
Step-by-step explanation:
You said that she poured 1 1/5 pouches in each cup. There are 5 cups, so multiply 1 1/5 by 5.
(e.g)
1 1/5+1 1/5= 3 because 1+1=2 & 1/2+1/2=1 so you add them and get 3
Do that twice and you get 6
then you have 1 one more cup left so add 1+6=7 then add the half 7+1 1/2=7 1/2
