After simplifying both sides of the equation and isolating the variable, x = 4
Answer:
x = 3
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
45x is an exterior angle of the triangle, hence
45x = 25x + 57 + x
45x = 26x + 57 ( subtract 26x from both sides )
19x = 57 ( divide both sides by 19 )
x = 3
Answer:
Step-by-step explanation:
Let the time taken to reach 12,000 feet = x
Distance traveled in 1 minute = 2000 ft
Distance traveled in 'x' minute = 2000 * x = 2000x
30,000 - 2000x = 12000
Add 2000x to both sides
30,000 = 12000 + 2000x
Now subtract 12,000 from both sides
30000 - 12 000 = 2000x
2000x = 18 000
Divide both sides by 2000
x = 18000/2000
x = 9 minutes
