3.1.5: () =0.75= () /== ():28=30

To solve the equation, let's break it down step by step: 1. First, let's determine the value of (). Given that () = 0.75, we substitute 0.75 into the equation: 0.75 = () / () 2. Next, we need to find the value of (). To do this, we multiply both sides of the equation by (): 0.75 × () = () 0.75 = () So, ( ) equals 0.75. 3. Now, let's focus on the equation (): 28 = 30. In this case, we can see that the value is () multiplied by 28 equals 30. 4. To find the value of (), we divide both sides of the equation by 28: ()/28 = 30/28 5. Simplifying the right side of the equation, we have: ()/28 = 15/14 6. Multiplying both sides of the equation by 28: () = 15/14 × 28 () = 30 Therefore, ( ) equals 30. In summary: ()-0.75 ()-30
