Answer:
no, because the runner is short by 480 feet
Step-by-step explanation:
there are 5280 feet in 1 mile
5280 feet= 1 mile                             20 feet= 1 second (times by 240)
                                                                4800 feet=            240 seconds
he is 5280-4800= 480 feet less

To solve this problem, we are going to set up an equation.  Let the number that we are trying to find be represented by the variable x.  If we plug in the numbers that we know, we get the following equation:
3x/4 = 24
To simplify this equation, we need to multiply both sides by 4, to begin getting the x alone on the left side of the equation.
3x = 96
Finally, we need to divide both sides by 3, to get rid of the coefficient that is being multiplied to x.
x = 32
Therefore, the number that you are trying to find is 32.
        
                    
             
        
        
        
Answer: -1
Step-by-step explanation: First, factor out 3.6. You should get -m+3. Since the coefficient is just the number being multiplied to the variable (which is m here), your coefficient should be -1 because m is being multiplied to -1 to make -m. Hope this helps!
 
        
             
        
        
        
The solution is n= <u>+</u> 4i/√11
Step-by-step explanation:
step 1: 10n^2+n^2+16=0
step 2: 11n^2+16=0
step 3: 11n^2= -16
step 4: n^2= -16/11
step 5: taking square root on both sides,
             n= √(-16)/√11 (square root of a negative number is a <u>complex term</u> 'i')
             n= <u>+</u> 4i/√11
