assuming this means 6 equal lengths
divide 2 meters by 6
2/6 =0.333 meters each
0.333 meters = 333.33 mm
rounded off to nearest whole mm would be 333 mm's
Add 20 both sides
15x<150
divide bothsides by 15
x<10
ok
hmm
bob puts out 15lb of trash per day
he lost 20lbs of it
right now, he has less than 130 lb of trash
find how many days it has been
Because the average is 7.7, his total points are equal to 7.7*10=77.
Because 7*10<77<8*10, Luke cannot have scored 8 10s. We now seek to prove that he can score 7 tens.
This leaves him with three tests left, that sum to 7 marks. There are clearly many ways to arrange this - for example, 2, 3, and 3 on the first three tests, then ten on all seven other tests. As this shows that 7 10s works and we have proven that 8 10s does not work, 7 is the maximum amount of 10s Luke could have scored.
Answer:I think all you need to do is 0.5*4.5 and you will get your answer
