Answer:
2
Step-by-step explanation:
2x²-5x-3 = 0
(2x+1) (x-3) = 0
2x+1 = 0
2x = -1
x = -½
x-3 = 0
x = 3
then x = -½ , x= 3
Answer: Total distance travelled is 510 km
Step-by-step explanation:
it is given that an automobile travels for
2 hours at 80km/h
3 hours at 110km/h
30 min at 40km/h
to find distance=x(let)
since
distance = speed * time
so
x= 80*2 +110*3 +40*(1/2) [since 1 hour =60 min so 30 min =1/2 hour]
x=160+330+20
x=510
hence total distance travelled is 510 km

If one box contains 10 grapefruits and there were 20,400 boxes in one season, then all we need to do is to multiply 20,400 by 10:
20,400 * 10 = 204,000
So the citrus grower shipped 204 thousand grapefruits.
