<h3>Given Equation:-</h3>

$\boxed{ \tt \frac{3}{x + 5} - \frac{2}{x - 3}}$

<h3>Step by step expansion:</h3>

$\dashrightarrow\sf\dfrac{3}{x + 5} - \dfrac{2}{x - 3}$

Write the equation

$\\ \\$

$\dashrightarrow\sf\dfrac{\frac{3 \times (x + 5)(x - 3)}{x + 5} - \frac{2 \times (x + 5)(x - 3)}{x - 3}}{(x + 5)(x - 3)}$

Take the lcm of the equation I.e (x + 5) (x + 3)

$\\ \\$

$\dashrightarrow\sf\dfrac{\frac{3 \times \cancel{(x + 5)}(x - 3)}{\cancel{x + 5}} - \frac{2 \times (x + 5)\cancel{(x - 3)}}{\cancel{x - 3}}}{(x + 5)(x - 3)}$

cancel like terms I.e (x + 5) with (x+ 5) and (x - 3) with (x - 3)

$\\ \\$

$\dashrightarrow\sf\dfrac{\frac{3 \times (x - 3)}{1} - \frac{2 \times (x + 5)}{1}}{(x + 5)(x - 3)}$

$\\ \\$

$\dashrightarrow\sf\dfrac{3 \times (x - 3)- 2 \times (x + 5)}{(x + 5)(x - 3)}$

Remove 1 as denominator

$\\ \\$

$\dashrightarrow\sf\dfrac{3x - 9- 2 (x + 5)}{(x + 5)(x - 3)}$

Multiply 3 with x - 9

$\\ \\$

$\dashrightarrow\sf\dfrac{3x - 9- 2 x - 10}{(x + 5)(x - 3)}$

Multiply - 2 with x + 5

$\\ \\$

$\dashrightarrow\sf\dfrac{3x - 2x- 9 - 10}{(x + 5)(x - 3)}$

Arrange the equation so that it would be easier to solve.

$\\ \\$

$\dashrightarrow\sf\dfrac{x- 9 - 10}{(x + 5)(x - 3)}$

Subtract 3x with 2x

$\\ \\$

$\dashrightarrow\bf\dfrac{x-19}{(x + 5)(x - 3)}$

Add -9 with - 10

$\\ \\$

$\therefore \underline {\textsf{\textbf{Option \red{one} is correct}}}$

An isosceles triangle has an angle that measures 68°. Which could be the measure of another angle in the triangle? A. 22° B. 56°

Lisa [10]

Answer:

B

Step-by-step explanation: 68+x+x=180. subtract 68 from both sides, and simplify the x's. so 2x=112. than divide by 2. x=56

How many blue candles are there in a basket of 490 candles, if there are 3/4 as many orange candles as blue?

Mrrafil [7]

Answer:

210 orange candles

280 blue candles

Step-by-step explanation:

x = blue candles

y = orange candles

y = 0.75x

x + y = 490

x + 0.75x = 490

1.75x = 490

x = 280

280 + y = 490

y = 210
