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
