Answer:
4x - 3
Step-by-step explanation:
(7x - 2) - (3x - 5)
Open the bracket and observe the signs,
7x -2 - 3x + 5 ( when the minus outside the bracket multiplies minus in the bracket, it becomes plus)
Collect like terms
7x - 3x - 2 + 5
4x - 3

Step-by-step explanation:
Length of parking lot = 20 feets
Speed of tortoise which starts at the edge = 6 feets per minute
Speed of tortoise which starts 4 feets from the edge = 2 feets per minute
Equation to represent when they will be in the same spot.
Distance = speed * time
Distance of Tortoise at edge = 6ft/min * t = 6t - - (1)
Distance of the other tortoise = (4 + 2t) - - - (2)
Equating both (1) and (2)
6t = 4 + 2t
6t - 2t = 4
4t = 4
t = 4/4
t = 1
Hence, they'll be at the same spot after 1 minute.
