Answer:
The solution is x = 1 because 2(1) - 1 = -1
Step-by-step explanation:
Step-by-step explanation:
4[5x-3x(2-2x)]
=4[5x-6x+6x^2]
=4[-x+6x^2]
=-4x+24x^2
Let's change all of them into seconds so it is easier to compare:
Pamela: 51 seconds.
Lucy: 3/5 minute x 60 = 36 seconds
Kady: 8 minutes x 60 = 480 seconds
Thus, Kady can stay underwater the longest.
Answer:
Answer:
17 seedlings
Step-by-step explanation:
Given;
The seedlings are at an equal distance in a straight line.
Distance between 3rd seedling and 5th seedling = 9/10 m
So, distance between 3rd seedling and 4th seedling = 9/10 ÷ 2 = 9/20 m
So, the distance between two seedlings in a line = 9/20 m
The given distance between 2nd seedling and the last seedling = 6 3/4 m = 27/4 m
