Please help, solve for x and n

Vlada [557]

Answer:

1. $\boxed{ \bold{ \huge{ \boxed{ \sf{x = 1}}}}}$

2. $\boxed{ \bold{ \huge{ \boxed{ \sf{n = - 5}}}}}$

Step-by-step explanation:

1. $\sf{ \frac{6}{x + 1} = \frac{3}{x} }$

Do cross multiplication

$\dashrightarrow{ \sf{6x = 3(x + 1)}}$

Distribute 3 through the parentheses

$\dashrightarrow{ \sf{6x = 3x + 3}}$

Move 3x to left hand side and change it's sign

$\dashrightarrow{ \sf{6x - 3x = 3}}$

Collect like terms

$\dashrightarrow{ \sf{3x = 3}}$

Divide both sides by 3

$\dashrightarrow{ \sf{ \frac{3x}{3} = \frac{3}{3} }}$

Calculate

$\dashrightarrow{ \sf{x = 1}}$

The value of x is 1

---------------------------------------------------------------------

2. $\sf{ \frac{2}{6} = \frac{2n + 8}{n - 1}}$

Do cross multiplication

$\dashrightarrow{ \sf{2(n - 1) = 6(2n + 8)}}$

Distribute 2 through the parentheses

Similarly, distribute 6 through the parentheses

$\dashrightarrow{ \sf{2n - 2 = 12n + 48}}$

Move 12n to left hand side and change it's sign

Similarly, move 48 to right hand side and change it's sign

$\dashrightarrow{ \sf{2n - 12n = 48 + 2}}$

Collect like terms

$\dashrightarrow{ \sf{ - 10n = 48 + 2}}$

Add the numbers : 48 and 2

$\dashrightarrow{ \sf{ - 10n = 50}}$

Divide both sides by -10

$\dashrightarrow{ \sf{ \frac{ - 10n}{ - 10} = \frac{50}{ - 10} }}$

Calculate

$\dashrightarrow{ \sf{n = - 5}}$

The value of n is -5 .

Hope I helped!

Best regards! :D

Yuri purchased 8 trees to have planted at his house. The store charged a delivery fee of $5 per tree.

cestrela7 [59]

Answer:

$16.

Step-by-step explanation:

Let t represent the cost of each tree.

We have been given that Yuri purchased 8 trees to have planted at his house. So the cost of 8 trees will be 8t.

We are also told that the store charged a delivery fee of $5 per tree. So the delivery charges of 8 trees will be $8\times \$5=\$40$

The total cost of purchasing 8 trees will be $8t+40$ .

Since the total cost of the trees including the delivery was $168, so we can get an equation as:

$8t+40=168$

$8t+40-40=168-40$

$8t=128$

Upon dividing both sides of our given equation by 8, we will get:

$\frac{8t}{8}=\frac{128}{8}$

$t=16$

Therefore, the cost of each tree is $16.
