-5/4-(-1/6) help please

tiny-mole [99]

A way to add fractions that always works is to multiply each numerator by the denominator of the other, then express the sum of products over the product of the denominators.
$\dfrac{a}{b}+\dfrac{c}{d}=\dfrac{a}{b}\cdot\dfrac{d}{d}+\dfrac{c}{d}\cdot\dfrac{b}{b}\\\\=\dfrac{ad+bc}{bd}$

Here, you have
$\dfrac{-5}{4}-\dfrac{-1}{6}=\dfrac{-5\cdot6-(-1)\cdot4}{4\cdot6}=\dfrac{-26}{24}\\\\=\dfrac{-13}{12}=-1\frac{1}{12}$

The sum is -1 1/12

What value of x makes the equation -6x-20=-2x+4 (1-3×) true

dmitriy555 [2]

Answer:

x = 3

Step-by-step explanation:

-6x - 20 = -2x + 4 (1 - 3x)

Distributive property

-6x - 20 = -2x + 4 - 12x

Combine like terms

-6x - 20 = -14x + 4

Add 14x to both sides

-6x - 20 + 14x = -14x + 4 + 14x

Simplifying

8x - 20 = 4

Add 20 to both sides

8x = 24

Divide both sides by 8

x = 3

Integral of (sin(2x) + cos(2x)) dx=

Vinil7 [7]

$\displaystyle \int (\sin 2x + \cos 2x)~ dx\\\\=\displaystyle \int \sin 2x ~dx + \displaystyle \int \cos 2x ~ dx\\\\=-\dfrac{\cos 2x}2 + \dfrac{\sin 2x}2 +C\\\\=\dfrac{\sin 2x - \cos 2x}2+C$

-v + 5 + 6v = 1 + 5v + 3

Vedmedyk [2.9K]

Combine your like terms: 5v + 5 = 5v +4
subtract the 5v and 4 from each side: 0 = 1

because 0 $\neq$ 1, there is no solution
