- Midpoint Formula:

Step-by-step explanation:
<u>Step 1: Define</u>
Point P(1, 3)
Point Q(7, 7)
<u>Step 2: Identify</u>
P(1, 3) → x₁ = 1, y₁ = 3
Q(7, 7) → x₂ = 7, y₂ = 7
<u />
<u>Step 3: Find Midpoint</u>
Simply plug in your coordinates into the midpoint formula to find midpoint
- Substitute in points [Midpoint Formula]:

- [Midpoint] Add:

- [Midpoint] Divide:

Hypotenuse^2=12^2+5^2=144+25=169
⇒ hypotenuse =V169=13 cm
Fraction = 3/7
decimal = approximately 0.429
percentage = approximately 42.86%
Let x be the number of boys, then,
(3*x*18+x*y)/(3x+x)=17
(54+y)/4=17
y=14 points each boy.
