Answer: 7.5 minutes (7 min 30 sec)
Step-by-step explanation: If it takes it 3 minutes to travel 2 km, it would take it 1.5 minutes to travel 1 km. So, 1.5 * 5 = 7.5, meaning it would take it 7.5 min to travel 5 km.
Answer:
x^2+4x+2
Step-by-step explanation:
√4 = 2
=x^2+2x+2x+2
add the ones that are the same (2x+2x)
x^2+4x+2
-4,6
x^2 - 2x - 24 = 0
Factorise the equation
Products are -6 and 4
(x-6) (x+4) = 0
x = 6 and x = -4
Hope it helped!
Answer:
yes
Step-by-step explanation:
13-7=6 so that's the difference
Answer:
no solution
Step-by-step explanation:
2x + 4y = 6......reduces to x + 2y = 3
3x = 12 - 6y....reduces to x = 4 - 2y...rearranged is x + 2y = 4
so now we have :
x + 2y = 3
x + 2y = 4
ok....I dont have to go any farther to know that this has no solution because ur equations have the same slope and different y int, this means ur lines are parallel and have no solution because they never cross each others path.
