Answer:
2 + (4/7)
Step-by-step explanation:
9 x 2/7 = 18/7 = 2 + (4/7)
The answer to problem 14 is the equation c = 3i/e
To get this answer, you multiply both sides by 3 to undo the division of 3. Also, you divide both sides by 'e' to undo the multiplication of 'e'.
So it would look something like this
i = ec/3
3*i = 3*ec/3 ... multiply both sides by 3
3*i = ec
ec = 3i
ec/e = 3i/e ... divide both sides by e
c = 3i/e
==============================================
Problem 15)
P = 2L + 2W
2L + 2W = P
2L + 2W-2L = P-2L ... subtract 2L from both sides
2W = P-2L
2W/2 = (P-2L)/2 ... divide both sides by 2
W = (P-2L)/2
So the final answer is W = (P-2L)/2
Answer:
300 students
Step-by-step explanation:
To know the number of students, we must divide the total amount of milk spent by the amount spent for each and in this way we will obtain the value we are looking for, like this (both have the same units of L, so there is no problem ):
30 / (1/10) = 300
that is to say that there are a total of 300 students
1.5 miles/30 minutes is your unit rate. If you multiply the rate by 2 you would get 3 miles/hour.
So your final answer would be 3 miles per hour.
Hope this helps.
