The value of the sum expression \frac{x}{x +3} + \frac{3}{x + 3} is 1

<h3>How to determine the sum?</h3>

The expression is given as:

\frac{x}{x +3} + \frac{3}{x + 3}

Take the LCM of terms of the expression

\frac{x}{x +3} + \frac{3}{x + 3} = \frac{x + 3}{x +3}

Evaluate the quotient of x + 3 and x + 3

\frac{x}{x +3} + \frac{3}{x + 3} = 1

Hence, the value of the sum expression \frac{x}{x +3} + \frac{3}{x + 3} is 1

Perform the indicated operation. 15b/4 * 8/9a^2b^2
Sergio [31]

Answer:

The simplified expression is \frac{10}{3 a^2 b}

Step-by-step explanation:

The given expression is:

\frac{15b}{4} * \frac{8}{9a^2 b^2}

Multiply the items in the numerator together ( 15b * 8 = 120 b). Also multiply the items in the denominator together ( 4 * 9a²b² = 36a²b²). The expression thus becomes:

= \frac{120b}{36 a^2 b^2} \\\\

Divide both the numerator and the denominator by 12b:

= \frac{120b /12b}{36 a^2 b^2/12b}

The expression finally becomes:

= \frac{10}{3 a^2 b}

-86

Step-by-step explanation:

We have been given that the elevation of driskill mountain Louisiana is 163 meters above sea level. The death Valley has an elevation of -86 meters.

We can represent this information in an inequality as: -86. Our inequality means that the elevation of death valley is less than elevation of driskill mountain.

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
