Answer:

$x = - 12$

C.E.: x <em>=/=</em> -4

Step-by-step explanation:

$\frac{x}{x + 4} = \frac{4}{x + 4} + 2 \\ \frac{x}{x + 4} = \frac{4 + 2x + 8}{x + 4} \\ x = 4 + 2x + 8 \\ - x = 12 \\ x = - 12$

Ymorist [56]

Answer:

Final cost = 0.9328y

Step-by-step explanation:

Assume,

Original price = y

Given:

Discount = 22%

Sales tax = 6%

Computation:

Sales tax will be added on sale value

So,

Sales price = y[100%-22%]

Sales price = 0.88y

Price after sales tax :

Final cost = 0.88y[100% + 6%]

Final cost = 0.88y[106%]

Final cost = 0.9328y

Find how many solutions there are to the given equation that satisfy the given condition.

den301095 [7]

Answer:

17550 solutions

Step-by-step explanation:

Given that:

y1 +y2+y3+y4=27

where;

(yi ≥ 0 and yi $\epsilon$ $\mathbb {Z}$ )

The no. of a nonnegative integer determines the number of ways to choose 27 objects from (4) distinct objects with repetition regardless of the order.

i.e

$\bigg(^{27}_{4} \bigg)$

∴

The number of nonnegative integer solution is $\bigg(^{27}_{4} \bigg)$

$= \dfrac{27!}{4!(27-4)!}$

$= \dfrac{27!}{4!(23)!}$

$= \dfrac{27\times 26\times 25\times 24 \times 23 !}{4\times 3\times 2\times 1(23)!}$

$= \dfrac{27\times 26\times 25\times 24 }{4\times 3\times 2\times 1}$

$= \dfrac{421200}{24}$

= 17550 solutions
