48/4 = 12
Mikhail’s age is 12 and Gabriel’s age is 36.
Answer:
14) y = 81
15) n = 6
Step-by-step explanation:
14)
54:30 = y:45
cross multiply: 45(54) = 30y, so y = 81
15)
6:3 = 12:n
cross multiply: 12(3) =6n, so n = 6
Answer:
89.25
Step-by-step explanation:
If you do 10.50
x 8.5 you get 89.25.

Coordinates of the point that partitions the line into the given ratio is; (1, 5)
<h3>How to divide a line segment?</h3>
If the ratio dividing a line segment represents a:b, then the formula to divide the line segment is;
Coordinates = {(bx₁ + ax₂)/(a + b), (by₁ + ay₂)/(a + b)}
From our question, we have the ratio as;
1:2. Thus; a = 1 and b = 2
Our coordinate of CD is; C(-1,7) and D(5, 1)
Thus;
x₁ = -1
x₂ = 5
y₁ = 7
y₂ = 1
Coordinates of the point that partitions the line into the given ratio is;
Coordinate = {(2*-1 + 1*5)/(1 + 2), (2*7 + 1*1)/(1 + 2)}
Coordinate = (3/3, 15/3) = (1, 5)
