You simplify your ratio as much as you can, then make it a fraction. Once it’s in the form of a fraction, it’s easier to make it into a percent

anygoal [31]

Alright, lets get started.

Mr. Hinckley owns 83 acres of total land.

He divides the land into eight equal sections to sell to eight buyers.

It means, we could find the land each buyer receives by dividing total land by 8.

So, each buyer receives land = $\frac{83}{8}$

So, each buyer receives land = 10.375 acres

So, the answer is 10.375 acres lands received by each buyer. : Answer

Given that 5 x − 3 y = 32 Find y when x = 4

ollegr [7]

Answer:

Solution,

X=4

Now,

 $5x - 3y = 32 \\ or \: 5 \times x - 3y = 32 \\ or \: 5 \times 4 - 3y = 32 \\ or \: 20 - 3y = 32 \\ or \: - 3y = 32 - 20 \\ or \: - 3y = 12 \\ or \: y = - \frac{12}{ 3} \\ y = - 4$ 

Hope this helps...

Good luck on your assignment..
