distance travelled = 2m
time travelled = 2s
speed = 2/2 = 1m/s
2-3
distance travelled = 2.7m
time travelled = 1s
speed = 2.7/1 = 2.7m/s
4-6
distance travelled = 0m
time travelled = 2s
speed = 0/2 = 0m/s (not moving)
Ответ:
x=-2
Step-by-step explanation: First we can multiply 4 times anything in the parenthesis to get rid of it.
(2x-6)+4(x-3)
(2x-6)+4x-12
Then we combine like terms.
(2x-6)+4x-12
6x-6-12
6x-18
Finally we divide both sides by 6.
6x-18
6x/6-18/6
x=-2
