Can anyone help me with this? Reduce the fraction

$\bf ~\hspace{7em}\textit{negative exponents} \\\\ a^{-n} \implies \cfrac{1}{a^n} ~\hspace{4.5em} a^n\implies \cfrac{1}{a^{-n}} ~\hspace{4.5em} \cfrac{a^n}{a^m}\implies a^na^{-m}\implies a^{n-m} \\\\[-0.35em] \rule{34em}{0.25pt}$

$\bf \cfrac{-20t^5u^2v^3}{48t^7u^4v}\implies \cfrac{-20}{48}\cdot \cfrac{t^5u^2v^3}{t^7u^4v^1}\implies \cfrac{-5}{12}\cdot \cfrac{v^3v^{-1}}{t^7t^{-5}u^4u^{-2}}\implies \cfrac{-5}{12}\cdot \cfrac{v^{3-1}}{t^{7-5}u^{4-2}} \\\\\\ \cfrac{-5}{12}\cdot \cfrac{v^2}{t^2u^2}\implies \cfrac{-5v^2}{12t^2 u^2}$

Pete has 4 packs of gum balls. Each pack has 5 gum balls. If Pete gives the same number of gum balls to 6 friends, how many gum

hodyreva [135]

Answer:

3 1/3 gum balls per friend

Step-by-step explanation:

Packs of gum balls Pete has = 4

Each pack = 5 gum balls

Total gum balls Pete has = Number of packs of gum balls × Number of gum balls in each pack

= 4 × 5

= 20 gum balls

Pete gives the same number of gum balls to 6 friends.

Each friend gets = Total gum balls / number of friends

= 20 gum balls / 6 friends

= 3 2/6 gum balls per friend

= 3 1/3 gum balls per friend

A) Factorise 2x² - 9x - 5 (x-5)(2x+1) (2) b) Hence, simplify fully 2x^2- 9x - 5 3x – 15x (2)

Lyrx [107]

Answer:

Step-by-step explanation:

b).

2x² - 9x - 5 = ( x - 5 )( 2x + 1 )

3x² - 15x = 3x ( x - 5 )

$\frac{(x-5)(2x+1)}{3x(x-5)}$ = $\frac{2x+1}{3x}$
