your number was 12.
let x be the number:
(x * 2) + 50 = 74
To solve for x, we need to reverse what was done to get the answer of 74.
Since 50 was added to arrive at 74, we deduct 50 from 74.
74 - 50 = 24
We then divide 24 by 2 to get the original number.
24/2 = 12.
Your number was 12.
To check:
(12 * 2) + 50 = 74
24 + 50 = 74
74 = 74
V = 20.88 km / h ( velocity )
d = 145 km ( distance )
Velocity formula: v = d / t
t = d / v ( time )
t = 145 km : 20.88 km/h
t = 6.94444 h
We have to multiply 0.94444 by 60 minutes.
0.94444 · 60 = 56.67 ≈ 56 minutes 40 seconds
Answer: It would take 6 hours 56 minutes and 40 seconds.
Answer:
Scales are used to represent real distances and proportions into maps and planes, that way we can have a bigger perspective about something just having in paper.
One direct use of scales are seen in architecture plans, there, the architect uses scales to represent the construction he is designing. Also, the architect can have a more complete point of view about the principial elements on his work.
