Answers
The above is the ‘b’ question.
We can get to know who long he takes to complete 1 mile taking the mean of the two in the double number line.
In this case it would be, the mean if 2 to get 1 and the mean of 19,
The mean of 2 is,
2miles / 2 = 1 mile.
And the mean of 19 mins is,
19 mins / 2 = 9.5 mins.
Hence, Gabrielle takes 9.5 mins to complete 1 mile.

Change the following mixed expressions to fractions and then simplify the complex fractions.
Answers
Answer:
[tex]\frac{3(a-7)}{4x(a-4)}[/tex]
Step-by-step explanation:
One is given the following expression:
[tex]\frac{2a^2-9a-35}{12x^3}*\frac{9x^2}{2a^2-3a-20}[/tex]
The most logical first step to solve this equation is to factor it. Rewrite each quadratic equation as the product of two linear equations. Unfortunately, no additional explanation can be provided. To prove that the product of the two linear terms are the factors of the quadratic term, one must distribute and simplify,
[tex]\frac{2a^2-9a-35}{12x^3}*\frac{9x^2}{2a^2-3a-20}[/tex]
[tex]\frac{(2a+5)(a-7)}{12x^3}*\frac{9x^2}{(2a+5)(a-4)}[/tex]
Now simplify this expression, then cancel common terms in the numerator and denominator,
[tex]\frac{(2a+5)(a-7)}{12x^3}*\frac{9x^2}{(2a+5)(a-4)}[/tex]
[tex]\frac{9x^2(2a+5)(a-7)}{12x^3(2a+5)(a-4)}[/tex]
[tex]\frac{3(a-7)}{4x(a-4)}[/tex]
