30-3=27
27 divided by 3=9
So, david bought 9 apples
Wouldn't you just multiply 120 by 0.95
The answer to your question is 600
Answer:
85+35 = 120
175-120 = 55
55 + 250 = 305
Step-by-step explanation:

K(-5,-2) and M(5,4)
S(-3,6) and T(3,-4)
Let's calculate the slope m₁ of KM
m₁ = (y₂-y₁)/(x₂-x₁) → m₁ =(4+2)/(5+5) = 6/10 →m₁ = 3/5
Now let's calculate the slope m₂ of ST:
m₂ = (-4-6)/(3+3) → m₂ = (-10)/6 → m₂ = -5/3
We can conclude that KM and ST are perpendicular since thee product of their respective slopes (m₁).(m₂) = - 1
Proof: (3/5).(-5/3) = -15/15 = -1
