Solve the following equation 1/x-1+1/x+2=3

Mathematics
1 answer:
disa [49]4 years ago

Answer:

x = 1

Step-by-step explanation:

Solve for x over the real numbers:

-1 + 2 + 1/x + 1/x = 3

-1 + 2 + 1/x + 1/x = 1 + 2/x:

1 + 2/x = 3

Bring 1 + 2/x together using the common denominator x:

(x + 2)/x = 3

Multiply both sides by x:

x + 2 = 3 x

Subtract 3 x + 2 from both sides:

-2 x = -2

Divide both sides by -2:

Answer:  x = 1

asambeis [7]
The formula for the volume of a sphere is V= \frac{4}{3}  \pi r^3. Plugging in 4.7 for your radius, we get V= \frac{4}{3} \pi 4.7^2= \frac{4}{3} \pi 22.09= \frac{88.36}{3} \pi, which is roughly 29.453π≈92.530.

1) What is the value of the expression 3 4 + 15.45 - 19.75 + 7.87?
Delvig [45]

Answer:

37.57

Step-by-step explanation:

34 + 15.45 - 19.75 + 7.87

34 + 15.45 = 49.45

49.45 - 19.75 + 7.87

49.45 + 7.87 = 57.32

57.32 - 19.75 = 37.57

|w| + 1.2 > 0.8 solution or no solution
Tasya [4]

You said              | w | + 1.2 > 0.8

Subtract  1.2  from each side:    | w | > -0.4

The absolute value of a number is always positive.
EVERY value of 'w' has an absolute value greater than -0.4 .
EVERY number is a solution to the equation.
There are an infinite number of them.
