Answer:
t = 1, but please check to see if I correctly interpreted your formatting.
Step-by-step explanation:
The format of the question is too confusing.
I'll assume this is the equation to be solved:
<u>16−2t=t+9+4t</u>
<u></u>
16−2t=t+9+4t
16-9 = t + 2t + 4t
7 = 7t
t = 1
Answer:
First Answer: y= 64 and x=64
Second Answer: 1&4, 2&3, 6&7, 5&8
Step-by-step explanation:
First Answer: 63 and ∠y is the same measure since there are
Second answer: They are vertical angles, each of the pairs of opposite angles made by two intersecting lines.
Hope this helps:)
C. 0.25 because you divide 0.06 by 0.24
Answer:
(0,-5) and (-4,3)
Step-by-step explanation:
The given equations are
Make y the subject in the second equation;
Substitute into the first equation;
Expand:
When x=0,
This gives; (0,-5)
When x=-4
This gives (-4,3)
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)
