$\frac{(x+1)(x-1)}{(x+1)(x-1)(x+1)} - \frac{2(x-1)}{(x+1)(x-1)(x+1)} + \frac{3(x+1)}{(x+1)(x-1)(x+1)}$

= $\frac{x^2-2-2x+2+3x+3}{(x+1)(x-1)(x+1)}$
= $\frac{x^2+x+4}{(x+1)(x-1)(x+1)}$ is what I got.

10. 2x + 7y = 1 2x - 4y = 12 Solve for y

adoni [48]

Answer:

The solution for y = -1.

Step-by-step explanation:

Given:

$2x\ +\ 7y\ =\ 1$ ....(1)

$2x\ -\ 4y\ =\ 12$ ....(2)

So, to solve for y, first we solve for x in equation (2):

$2x-4y=12$

⇒ $2x=12+4y$

Dividing both sides by 2,

⇒ $x=6+2y$

Now, substituting the value of x in equation (1):

$2x+7y=1$

⇒ $2(6+2y)+7y=1$

⇒ $12+4y+7y=1$

⇒ $12+11y=1$

⇒ $11y=1-12$

⇒ $11y=-11$

Dividing both sides by 11,

⇒ $y=-1$

Therefore, the solution for y = -1.

Suppose you are driving to visit a friend in another state. you are driving 55 miles per hour. you must drive 440 miles total. i

Oliga [24]

Time=(distance)/(speed)
speed=55 mi/hr
Total distance=440 miles
Distance covered=275 miles
remaining distance=440-275=165 miles
Time taken to cover the remaining distance will be:
time=165/55=3 hours

Total time taken to travel=440/55=8 hours
if we are to use the equation given by:
55h+275=440
time taken will be found by solving for h, thus we shall have:
55h=440-275
55h=165
h=165/55
h=3 hours

Answer: 3 hours
