How do I do this??????? 2/3x-(1/2x+1)<br>btw need it simplified

Setler79 [48]

Answer:

1/6x -1

Step-by-step explanation:

"Simplify" generally means, "eliminate parentheses and combine like terms." In general, parentheses are eliminated by making use of the distributive property.

__

$\dfrac{2}{3}x-\left(\dfrac{1}{2}x+1\right)=\dfrac{2}{3}x-\dfrac{1}{2}x-1=\left(\dfrac{2}{3}-\dfrac{1}{2}\right)x-1\\\\=\left(\dfrac{4}{6}-\dfrac{3}{6}\right)x-1=\boxed{\dfrac{1}{6}x-1}$

Osian was 1.5 m tall. In the last couple of years,his height has increased by 20%

3241004551 [841]

For this case we must find the current height of Osian. For this, we use the following rule of three:

1.5 m ----------------> 100%

x -----------------------> 120%

From here, we clear the value of x.

We have then:

$x = \frac {120} {100} (1.5)\\x = 1.8 m$

Answer:

The current height of Osian is given by:

$x = 1.8 m$
