Answer:
option A. 21 sec
Step-by-step explanation:
Speed = the distance over the time
Given:
Speed = 2 m/s and distance = 42 m and time = t
So,
2 = 42/t
Solve for t
t = 42/2 = 21 sec.
The answer is option A. 21 sec
Answer:
x = 15
Step-by-step explanation:
The two angles form a straight line so they add to 180 degrees
3+6x + 5x+12 = 180
Combine like terms
11x+15 = 180
Subtract 15 from each side
11x+15-15 =180-15
11x = 165
Divide by 11
11x/11 =165/11
x =15
The answer is C. y = - 2x - 1
hope that helps!! :)
