2/3x=26
multiply both sides by 3/2 to get x by itself
2/3x(3/2)=26 (3/2)
Cross out 2s and 3s. Divide by 2 and 3.
Then becomes 1*1*1*1*x=x
26(3/2)
Cross out 26 and 2. Divide by 2.
26/2=13
2/2=1
13*3=39
Answer:
x=39

Answer:
C. 20
Step-by-step explanation:
You need you use the Pythagorean Theorem to answer this. We are given the lengths of both legs of the right triangle.
a^2 +b^2 = c^2
If we plug the number given to us into the formula, we get
(12)^2 + (16)^2 = c^2
144 + 256 = c^2
400 = c^2
= C
20 = C
For the purpose of showing the solution to this item, we let the basis in which we are to determine the number of trains that passed through be 1 day. That being said, we convert 1 day to number of minutes by using the correct conversion factor and dimensional analysis as below.
(1 day)(24 hours/1 day)(60 minutes/1 hour) = 1440 minutes
Then, divide the calculated number of minutes by 20.
number of trains = 1440 minutes x (1 train / 20 minutes)
number of trains = 72 trains
Answer: 72 trains
