The answer is 9x+8. if you distripute the 2, you get 2x-6. if you distribute the 7, you get 7x+14. then you combine like terms ans get 9x+8
Answer:
4.8 hours
Step-by-step explanation:
Step one:
given data
The total distance= 220 miles
The velocity of the train= 3/4 mile per minute
Required
The time of travel
Step two:
we know that
velocity= distance/time
velocity= 220/3/4
let us multiply the numerator (220) by the inverse of the denominator(4/3)
velocity =220*4/3
velocity= 880/3
velocity= 293.3 minutes
in hours
= 293.3/60
= 4.8 hours
The range is the difference between the longest hike and the shortest hike.
Longest = 5
Shortest = 1
Range = 5-1 = 4 miles
Answer: y=3
Step-by-step explanation: y would be 3 because in the problem, x is being multiplied,so to do the inverse, you'd need to divide. 6 divided by 2 is 3.
Answer:
The value of x = 14 ...
The value of ∠AED = ( 7x + 15) = 7(14) + 15 = 113
The value of ∠AEB = 5x-3 = 5(14) -3 = 67
Step-by-step explanation:
=> ∠BEC = ∠AED { vertically opposite angles }
∠AED = (7x + 15)°
=> ∠AEB + ∠BEC = 180° { linear pair }
=> ( 5x-3) + ( 7x+15) = 180°
=> 5x -3 + 7x + 15 = 180°
=> 12x + 12 = 180°
=> 12( x +1 ) = 180°
=> x+1 = 180/12
=> x +1 = 15
=> x = 15-1
=> x = 14
