Multiply both sides of the each equation in order to get the coefficient to be an integer.

monitta

$45= \frac{1}{2}a-3 //+3 \\ 48= \frac{1}{2} a// : \frac{1}{2} \\ 48: \frac{1}{2}=a=\ \textgreater \ 48*2=a=\ \textgreater \ a=96$
Hope that helps.Have a nice day!! ^^

Solve the following proportion for 17/13=9/u

ValentinkaMS [17]

Answer:

<h2>u = 6.88</h2>

Solution,

$\frac{17}{13} = \frac{9}{u}$

Sinplify the equation using cross multiplication

$17 \times u = 13 \times 9$

Calculate the product

$17u = 117$

Divide both sides of the equation by 17

$\frac{17u}{17} = \frac{117}{17}$

Calculate

$u = 6.88$

Hope this helps...

Good luck on your assignment..
