Answer:
24
Step-by-step explanation:
Arrange the terms in ascending order.
20, 22, 23, 24, 24, 25, 46
The median is the middle term in the arranged data set.
<em>good luck, i hope this helps :)</em>
Step 1: Simplify both sides of the equation.
−2(x−6)=−5(x+3)
(−2)(x)+(−2)(−6)=(−5)(x)+(−5)(3)(Distribute)
−2x+12=−5x+−15
−2x+12=−5x−15
Step 2: Add 5x to both sides.
−2x+12+5x=−5x−15+5x
3x+12=−15
Step 3: Subtract 12 from both sides.
3x+12−12=−15−12
3x=−27
Step 4: Divide both sides by 3.
3x3=−273

Answer:
The rate increases at 398mi/h
Step-by-step explanation:
Given
--- rate when --- distance
<em>The given parameters is represented with the attached figure</em>
Using Pythagoras theorem [take the attached image as a point of reference]
Differentiate with respect to time (t):
Divide both sides by 2
--- (1)
When y = 2:
--- Pythagoras Theorem
Collect like terms
Solve for x
So:
Substitute: , and
Divide by 2
The answers to those two are both 90
