Answer:
The answer is 3
Step-by-step explanation:
The answer is 3 because x= 15/5 = 3
Answer:
therefore x = 600 mph
therefore the speed of the other plane y = x - 110 = 600 - 110 = 490 mph
Step-by-step explanation:
i) Two planes are 2725 miles apart and are travelling towards each other.
ii) One plane is travelling 110 mph faster than the other plane.
iii) the planes pass each other in 2.5 hours
iv) let the speed of one plane be x mph
v) let the speed of another plane be y mph
vi) therefore x - y = 110 mph
vii) and also x + y = 2725/2.5 = 1090
viii) adding the equation in vi) to the equation in vii) we get 2x = 1200
therefore x = 600 mph
ix) therefore the speed of the other plane y = x - 110 = 600 - 110 = 490 mph
Answer:
c. 0
Step-by-step explanation:
3(x+8) - 1 = 3x+4
3x+24-1 = 3x+4
3x+23 = 3x+4
There are no solutions since both equations have the same slope meaning they are parallel and they will never intersect since they have different y-intercepts.
It would be 6 because if it is .4 or below you round down and if it is .5 or above you round up
