Answer:
b = -2
Step-by-step explanation:
Start with your given:
-3b + 7 = 13
Subtract 7 on both sides:
-3b = 6
Then, divide -3 on both sides and solve:
b = -2
Answer:
-4
Step-by-step explanation:
-(-1) - (-2(-1) +3)
1 - (2+3)
1-5=-4
Answer:
Team 3 Turtle, by 4 minutes
Step-by-step explanation:
The speeds of each of the turtles can be computed from ...
speed = distance/time
Then for each of the turtles, the training pace is ...
Team 1 Turtle: (18 ft)/(6 min) = 3 ft/min
Team 2 Turtle: (12 ft)/(4 min) = 3 ft/min
Team 3 Turtle: (10 ft)/(2 min) = 5 ft/min
The times required to cover the 30 ft distance at these paces are ...
time = distance/speed
3 ft/min ⇒ (30 ft)/(3 ft/min) = 10 min
5 ft/min ⇒ (30 ft)/(5 ft/min) = 6 min
The 2nd-place finishers will take 10-6=4 minutes longer.
The expected winner is Team 3 Turtle by 4 minutes.
Distribute the 3a^n to all the other values then solve...
(3a^n*a^n)+(3a^n*a^n)+(3a^n*-1)
4a^2n+4a^2n-3a^n=
8a^2n-3a^n
