Im guessing he answered 30 correct, let me know if im correct
Answer:
1) B. n ≥ 3
2)A. 5x – 9
Step-by-step explanation:
1)
If the least value of n is 3 then all the values of n must be greater or equal to 3
Thus the correct option is B :n ≥ 3
2)
Given:
Milo's age is 9 years less than 5 times Pearl's age
Pearl's age is x years
5 times Pearl's age= 5x
then milo's age= 5x-9
so the correct option is A. 5x – 9 !
Okay so...
There are 21 groups of 3.
21 x 3 = 63.
63 people are in the room.
Do 180÷30=6.
Since 1 month is about 30 days
The answer is 6.
Step-by-step explanation:
65 km / h = 65,000 m / 3600 s
what do we need to multiply 3600 with to get 3 ?
3600 × f = 3
f = 3/3600 = 1/1200
now, we need to multiply 65,000 by the same factor to get how many meters the car is driving in these 3 seconds :
65000 × 1/1200 = 65000/1200 = 54.16666666...
so, rounded, it travels 54 meters in 3 seconds.
