<u><em>Answer:</em></u>
14 miles
<u><em>Explanation:</em></u>
<u>The relation that will be used to solve this problem is:</u>
<u>which can be rewritten as:</u>
<u>Assume that:</u>
Distance from your house to your friend's house is d
Time taken from your house to your friend's house is t₁
Time taken from your friends house to your house is t₂
<u>1- From your house to your friend's house:</u>
Average rate = 35 miles/hour
<u>Therefore:</u>
<u>2- From your friend's house to your house:</u>
Average rate = 40 miles per hour
<u>Therefore:</u>
<u>3- Round trip:</u>
We know that the round trip took 45 minutes which is equivalent to 0.75 hours
<u>This means that:</u>
t₁ + t₂ = 0.75 hours

Answer:
Step-by-step explanation:
m = 5 ; (3, -4)
y - y₁ = m (x - x₁)
y - [-4] = 5 (x - 3)
y + 4 = 5x - 15
y = 5x - 15 - 4
y = 5x - 19
Answer:
x = 1, y = -2, z = 3.
Step-by-step explanation:
x + 2y + 2z = 3 A
2x -2y - z = 3 B
x - 2z = -5 C
If we add equations A and B we eliminate y:
3x + z = 6 E
Multiply E by 2 :
6x + 2z = 12 F
Adding C and F we get:
7x = 7
x = 1.
Plug this into equaton C:
1 - 2z = -5
-2z = -5 - 1 = -6
z = 3.
Now plugging x = 1 and z = 3 in equation A:
1 + 2y + 2(3) = 3
2y = 3 - 1 - 6 = -4
y = -2.
Answer:
here's what I got from wikipedia (i dont like taking of other's brain skills :/ )
Step-by-step explanation:
<em>1:12 scale is a traditional scale (ratio) for models and miniatures, in which 12 units (such as inches or centimeters) on the original is represented by one unit on the model. Depending on application, the scale is also called one-inch scale (since 1 inch equals 1 foot)</em>
