Answer:
26 degrees Celcius
Step-by-step explanation:
The minimum temperature is -11
The maximum temperature is 15
to get from -11 to 0: add 11
to get from 0 to 15: add 15
11+15 = 26
Twice a number (2x) decreased by 7 (- 7).
2x - 7
Two times a specfic number (x) subtracted by 7.
The Given equation is , 3 x + x = 440,
Let speed of train A is x Km/hour and Speed of train B which is a Bullet train which starts from same station but from different platform is 3 times the speed of train A.
And Sum of their Velocities is i.e Velocity of train A and Velocity of train B is 440 Km/hour.
Answer:
x = 25
Step-by-step explanation:
it's an isosceles triangle so base angles are the same
3x - 30 = 45
Add 30 on both sides
3x = 75
divide both sides by 3
x = 25
