Can you extend the zero product property to non zero products of numbers? For example, if ab=8, is it always true that a=8 or b=

larisa [96]

That is not always true because think of it as ab=8 that is just like saying (8)(8)=8 which is absolutely false. If anything it can be either a or be equals 8 while the other variable is 1. (1)(8)=8 or (8)(1)=8

The sum of 13 divided by a number and that number divided by 13

7nadin3 [17]

Sum means add

the number is x

13 divided by a number is 13/x
the number divided by the number is x/13

so
$\frac{13}{x}+\frac{x}{13}$
also can be simplified to
$\frac{169}{13x}+\frac{x^2}{13x}$ or
$\frac{x62+169}{13x}$

translated it is $\frac{13}{x}+\frac{x}{13}$ where x is the number

On his drive from Montpelier, Vermont, to Columbia, South Carolina, Arthur averaged 51 mph. If he had been able to average 60 mp

Llana [10]

Answer:

Distance between Montpelier and Columbia is 1020

Step-by-step explanation:

51 mi/hr average:

d = 51 t

60 mi/hr average:

d t = 60*(t-3)

Substitute (1) into (2)

51 t = 60*(t-3)

51 t = 60 t + 180

9 t = 180

t = 20

d = 51 t

= 51 (20)

= 1020

let see distance is 1020 lets check

51 t = 60 * (t-3)

51 (20)= 60* (20-3)

1020 = 60*17

1020 = 1020
