Answer:
5/2 =
<u>2.5</u>
Step-by-step explanation:
Dividing a number by the ratio 3:2 means dividing into 3+2 = 5 parts
Let (0, 0) be (x₁, y₁) and (3, 6) be (x₂, y₂)
Find one part of the share for each axes, we do


Then multiplying the one part back into 3: 2, we have
for the x - axis ⇒ (3×0.6) : (2×0.6) = 1.8: 1.2
for the y - axis ⇒ (3×1.2) : (2×1.2) = 3.6: 2.4
The coordinate that divides the segment into 3 parts and 2 parts is (1.8, 3.6)
Correct answer: A
The algebraic expressions would be a÷9
10x+148.73=40x+440.83 solve this equation and then insert what u get from x into either y=10x+148.73 or y=40x+440.83
