Answer:

First, you have to factorize the expressions :

\frac{5x + 20}{8 {x}^{5} }  \times  \frac{x}{ {x}^{2}  - 16}

= \frac{5(x  + 4)}{8 {x}^{5} }  \times  \frac{x}{(x + 4)(x - 4)}

Second, you have to cross out the similar expressions :

= \frac{5}{8 {x}^{5} }  \times  \frac{x}{(x - 4)}

Third, you have to multiply both fractions :

=  \frac{5x}{8 {x}^{5}(x - 4) }

Lastly, you have to simplify :

=  \frac{5}{8 {x}^{4}(x - 4) }

Sarah would like to make a 6 lb nut mixture that is 60% peanuts and 40% almonds. She has several pounds of a mixture that is 80%
weeeeeb [17]

Answer: a. The system that models this situation is,

x + y = 6 , 8 x + 5 y = 36.

b. Solution is x = 2lb and y = 4lb

where x is the quantity of 80% of peanuts mixture mix with y quantity of 50% of peanuts mixture for making 60% of peanuts mixture.

Step-by-step explanation:

Let x quantity of 80% of peanuts mixture mix with y quantity of 50% of peanuts mixture for making 60% of peanuts mixture.

Then According to the question,

x + y = 6      --------- (1)

And, 80 % of x + 50 % of y = 60 % of 6

⇒ 0.8 x + 0.5 y = 3.6

⇒ 8 x + 5 y = 36  --------- (2)

Where equation 1) and equation 2) are the required equation which models the given situation.

Now, 8 × equation 1)

We get, 8 x + 8 y = 48 ----------(3)

equation (3) - equation (2)

we get, 3 y = 12

⇒ y = 4

By putting the value of y in equation (2)

we get, x = 2

Thus, he mixed 2 lb of mixture 80/20  and 4 lb of mixture 50/50 for making 6 lb of 50/50 mixture.
