Once cross multiplied you end up with this:
15x+75=20x−30
Next subtract 20x from both sides.
15x+75−20x=20x−30−20x
−5x+75=−30 -----------> Answer
Now subtract 75 from both sides
−5x+75−75=−30−75
−5x=−105
Now divide by -5 on both sides.
-5/-5x = -105/-5

x = 21 --------------> ANSWER</h3>
Answer:
<em>Distance ⇒ 5 meters</em>
Step-by-step explanation:
If we are to name the point with which Patrick stands P, Eddie's point E remains 4 meters south such that Dustin ( D ) is 3 meters to the right;
This in fact forms a 90 degree triangles, a right triangle with legs provided to be 4 and 3 knowing Eddie's remains 4 meters south, Dustin 3 meters to the right. If we are to determine how far apart Patrick and Dustin are, this is the hypotenuse of the right angle triangle formed, and the length can be determine through Pythagorean Theorem;
4^2 + 3^2 = x^2, x ⇒ distance between Patrick and Dustin,
16 + 9 = x^2,
x^2 = 25,
<em>Distance ( x ) ⇒ 5 meters</em>
Answer:
(5,10)
(3,6)
Step-by-step explanation:
The equation y=2x means that 2 multiplied by the first value would equal the second value, so this means that the second value is twice as much as the first value. This is not true for the first option because 8 is not twice of 16, and this is the same for (4,6), (4,2), and (1,3). Therefore (5,10) and (3,6) work.
Speed= distance/time.
6.4/4.
1.6 meters per minute.
