Answer:
 feet tall
 feet tall
Step-by-step explanation:
Ajax is "5 and 1 fourth feet tall", which can be written as the mixed number  .
 .
His sister is "3 eighths foot shorter", so she's 3/8 feet shorter than 5 1/4.
So, this is just a subtraction problem:

To solve this, we want to convert 5 1/4 into an improper fraction, which is:  . Now, we want to find a common denominator. In this case, that common denominator is 8, so
 . Now, we want to find a common denominator. In this case, that common denominator is 8, so  .
 . 
Finally, we subtract 3/8 from 42/8:  . So, Ajax's sister is 39/8 feet. Converting this into a mixed number, we have: 39/8 = 4
 . So, Ajax's sister is 39/8 feet. Converting this into a mixed number, we have: 39/8 = 4 .
 .
Therefore, Ajax's sister is  feet tall.
 feet tall.
Hope this helps!
 
        
                    
             
        
        
        
Answer:
OPTION B - 2
Step-by-step explanation:
What is the upper limit for the zeros of the function P(x) = 4x^4 + 8x^3 - 7x^2 - 21x - 9. Ans: 2 is an upper limit. Use synthetic division. and the remainder are all positive, 2 is an upper limit.

<h3>
♁ Question : Solve for x</h3>
<h3>♁ Step - by - step explanation</h3>
Move 12x to L.H.S ( Left Hand Side ) and change it's sign
➛
Move 7 to R.H.S ( Right Hand Side) and change it's sign
➛
Subtract 12x from 15x
Remember that only coefficients of like terms can be added or subtracted.
➛
Add the numbers : 2 and 7
➛
Divide both sides by 3

<h3>✒ Rules for solving an equation :</h3>
- If an equation contains fractions ,multiply each term by the L.C.M of denominators.
- Remove the brackets , if any.
- Collect the terms with the variable to the left hand side and constant terms to the right hand side by changing their sign ' + ' into ' - ' and ' - ' into ' + ' .
- Simplify and get the single term on each side.
- Divide each side by the coefficient of variable and then get the value of variable.
