Answer:
Ms. Montesinos has 5 fish in her tank
Step-by-step explanation:
a) Let y = the amount of fish Ms. Montesinos
b) 3y-2=13
c)
3y-2+=13+2
3y/3=15/3
y=5
It can be b), c) and d).
b) because it says the sum of three angles — this one’s the most obvious, as we can look at x, y and z as three different angles that sum up to 180.
c) works because 3a is, in essence, a + a + a, which we can look at as the sum of 3 angles that adds up to 180.
d) because we already have 2 angles, and “a” is just an unknown angle. It all sums up to 180.
a) and e) dont work because they involve multiplying (x*y*z and x*x*x) and the problem says we need to look for the sum of angles, not the product. :)
Her flight was 9 hours and 20 minutes.
Since 9 A.M. Karachi time is the same as 5 A.M. Warsaw time, we can take the time on her watch, Warsaw time, and subtract 4 to get the Karachi time.
Her watch said she left at 9:40 A.M. This is Warsaw time.
9:40 - 4 = 5:40 Karachi time.
Her flight took from 5:40 A.M. Karachi time to 3:00 P.M. Karachi time. This is 9 hours and 20 minutes.
