Answer:
150 steps
Step-by-step explanation:
GOING UP:
Steps taken per second = speed = 3steps/s
Let Time taken = y
Number of steps = steps taken per second × time taken
Number of steps = 3 × y - - - - (1)
COMING DOWN:
Steps taken per second = 2steps/s
Total time taken = y + 25
Number of steps = 2 × (y + 25)
Number of steps = 2y + 50 - - - - - (2)
Equating (1) and (2)
3y = 2y + 50
3y - 2y = 50
y = 50
Substitute y = 50 into either (1) or (2)
Put y= 50 into (1)
Number of steps = 3y
Number of steps = 3(50)
Number of steps = 150
Answer:
x > 3
Step-by-step explanation:
8x - 6 > 12 + 2x....,just move the values with variable x to one side and those without to the other side
; 8x - 2x > 12 + 6
; 6x > 18...., then divide by 6,both sides of the inequality
; x > 3
The answer to it is (-5,13),(1,1),(2,-1)
Answer:
Hence, 3/2 and 1 are the roots of the equation.
