Answer:
10, 4, 8
Step-by-step explanation:
10 - 4 = 6
4 - 4 = 0
8 - 4 = 4
First, sum up the total expenses for the original plan
Duque de Caxias + Campinas + Rio de Janeiro + Guarulhos = 242+185+193+120 = R$740
It is clearly over the intended budget. The average cost per itinerary is around R$200 so we will consider making a swap on either Duque de Caxias and Rio de Janeiro. Possible answers are (b) or (c)
for (b) Replace Duque de Caxias with Fortaleza, we will have
Fortaleza + Campinas + Rio de Janeiro + Guarulhos =
⇒ 201+185+193+120 = R$699 ⇒ This is exactly the budget intended for the trip
for (C) Replace Rio de Janeiro with Porto Alegre
Duque de Caxias + Campinas + Porto Alegre + Guarulhos =
⇒ 242 + 185 + 153 +120 = R$ 700 ⇒ This is over R$1
The answer is (b)
Hey there! :D
None of the sides are equal. We can tell this by just looking at it. If the side BC was a straight side, it would be a right triangle, but it is not. It doesn't have any right angles.
It is a scalene triangle. It has no equal sides and no equal angles.
I hope this helps!
