<span>The child should receive 217.724mg of medicine. Or rounded the child should receive 218mg of medicine.</span>

**Answer:**

x = 437.3 ft

**Step-by-step explanation:**

The angle at the top of the triangle = 90° - 29° = 61°

Using the sine ratio in the right triangle

sin61° = =

Multiply both sides by 500

500 × sin61° = x, hence

x ≈ 437.3

**Answer:**

y=y

**Step-by-step explanation:**

Assuming the question is to simplify:

Add 3x and 2x on the left side

5x+2y+2=3x+2x+2

Add 3x and 2x on the right side

5x+2y+2=5x+2y+2

Move all terms containing x to the left side of the equation

Subtract 5x from both side

5x+2y+2-5x=2y+2

x cancel out

2y+2=2y+2

Moving the constant to the right side of the equation

2y=-2+2y+2

Simplify

2y=2y

Divide 2

y=y

**Step-by-step explanation:**

There are 10 + 20 = 30 total students in the class.

Total marks for the class = 60 * 30 = 1800.

Total marks for the girls = 54 * 20 = 1080.

=> Total marks for the boys = 1800 - 1080 = 720.

Mean mark for the boys = 720 / 10 = 72.
