Divide 20 by 100 whixh equals .2, that gives us 1%. Now do .2×20 to get 20%. so 20% of 20 is 4, meaning 4 shirts are medium sized.
Answer:
Step-by-step explanation:
<u>Given vertices of triangle:</u>
- A(1, 2), B(3, 4), C(5, 0)
<u>The centroid is found as the average of x- and y- coordinates of three vertices:</u>
- C = ((x₁ + x₂ + x₃)/3, (y₁ + y₂ + y₃)/3)
<u>Substitute the coordinates into formula:</u>
- C = ((1 + 3 + 5)/3, (2 + 4 + 0)/3) = (3, 2)
Correct choice is B
Let n represent the number.
1/3n = n - 12
