What is -2 1/3- 1 1/3

romanna [79]

Answer:

Step-by-step explanation:

$-2\dfrac{1}{3}-1\dfrac{1}{3}=-2\dfrac{1}{3}+\left(-1\dfrac{1}{3}\right)=-\left(2\dfrac{1}{3}+1\dfrac{1}{3}\right)\\\\=-\bigg[(2+1)+\left(\dfrac{1}{3}+\dfrac{1}{3}\right)\bigg]=-\left(3+\dfrac{1+1}{3}\right)\\\\=-3\dfrac{2}{3}$

5. Find the value of x so that lines s and t are parallel.<br> (7x - 20)°<br> (4x + 16)

Thepotemich [5.8K]

The value of x so that lines s and t are parallel is 12

<h3 /><h3>How to find angles involving parallel lines?</h3>

The angle are alternate exterior angles.

Therefore, alternate exterior angle theorem states that when two parallel lines are intersected by a transversal, then the exterior angles formed on either side of the transversal are equal.

Hence,

7x - 20 = 4x + 16

7x - 4x= 16 + 20

3x = 36

x = 36 / 3

x = 12

Therefore, the value of x is 12.
