Answer:
Ratio = 1 : 4
Step-by-step explanation:
Total marbles = 10
Given 1/5 is red, that is 1/5 of the total marbles are red

Therefore , 10 - 2 = 8 marbles are blue.
Ratio of red marbles to blue marbles

The answer to the question can be found by setting up a proportion such as 7/14.4=x/24.6 which gives you 11.9583 ft
You are going to subtract.
<span>5/8 - 1/3 equals to 7/24</span>
A(x - x₁)(x - x₂) = 0
a=5, x₁=-3, x₂ = 3
so:
5(x-(-3))(x-3)=0
5(x+3)(x-3)=0
5(x²-9) = 0
5x² - 45 = 0 ← answer
