Answer:
<em>200mph</em>
Step-by-step explanation:
Speed is expressed using the expression
Speed = Distance/Time
For Mattie
Distance = 200miles
Speed = x
Time taken by mattie = Distance/speed
Time taken by mattie = 200/x ... 1
For the propeller plane:
Distance = 800miles
Speed = x+150 (The speed of the plane was 150 mph faster than the speed of the car)
time taken by the plane = 800/x+150
Since Mattie took the same amount of time that it took a turbo propeller plane to travel, then we will equate both expressions as shown:
200/x = 800/150+x
Cross multiply
800x = 200(150+x)
800x = 30,000 + 200x
800x-200x = 30,000
600x = 30,000
x = 30,000/600
x = 50
Get the speed of the plane
Since the speed of the plane is 150+x
Speed of the plane = 150+50
<em>Speed of the plane = 200mph</em>
6x26=156-7= 149
answer: 149
Answer:
57
Step-by-step explanation:
The midsegment is one half the length of the third side of the triangle, that is
6x + 3 = 
(3x + 87)
Multiply both sides by 2 to clear the fraction
12x + 6 = 3x + 87 ( subtract 3x from both sides )
9x + 6 = 87 ( subtract 6 from both sides )
9x = 81 ( divide both sides by 9 )
x = 9
Thus
midsegment = 6x + 3 = 6(9) + 3 = 54 + 3 = 57
3 km north.
the east and west cancel out and the 5 north being greater than the two south leave you to only have to subtract the 2 south from the 5 north
