Answer:
Q1. Option B
Q2. x>3
Q3. 62°
Q4. First three options are correct
Step-by-step explanation:
Q1. Solving the given options one by one. We get,
A. -1/4(y-1/2) = -1/4y + 1/8
B. 1/4(y-2) = 1/4y - 1/2
C. 1/4(y−1/2) = 1/4y - 1/8
D.−1/4(y−2) = -1/4y + 1/2
So, Option B is correct answer.
Q2. Solving the given equation,
5.5x+15.5>32
5.5x + 15.5 -15.5 > 32 -15.5
5.5x > 16.5
x > 3
Q3. Here, The third quadrant is of 90°
So, x = 90° - 28° = 62°
Q4. Since 3% of d = 0.03d
Also, Money given by bank + Money given by his grandmother
= 0.03d + 0.03d = 0.06d
So, total amount of money he get ater one year is d + 0.06d =1.06d
Hence, First three options are correct as 1.06d = d+0.06d = d+0.03d+0.03d

Recall your d = rt, distance = rate * time
so... one train goes west and the goes the opposite way... alrite... so... notice, by the time 338 miles have been covered by both, it will have been "t" hours, and whatever "t" is, is the same amount of time the westbound train has been running as well as the eastbound train has been running.
now, let's say, since by "t" hours they've covered 338 altogether, so, if the westbound train has covered say "d" miles, then the eastbound train would have covered the slack from 338 and d, that is, "338 - d".
so, 2hours and 36 minutes.
