(6x - 3) - (-3x + 2)
nadezda [96]

Answer:

Step-by-step explanation:

Simplifying

6x + -3 = (3x + -2)

Reorder the terms:

-3 + 6x = (3x + -2)

Reorder the terms:

-3 + 6x = (-2 + 3x)

Remove parenthesis around (-2 + 3x)

-3 + 6x = -2 + 3x

Solving

-3 + 6x = -2 + 3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-3x' to each side of the equation.

-3 + 6x + -3x = -2 + 3x + -3x

Combine like terms: 6x + -3x = 3x

-3 + 3x = -2 + 3x + -3x

Combine like terms: 3x + -3x = 0

-3 + 3x = -2 + 0

-3 + 3x = -2

Add '3' to each side of the equation.

-3 + 3 + 3x = -2 + 3

Combine like terms: -3 + 3 = 0

0 + 3x = -2 + 3

3x = -2 + 3

Combine like terms: -2 + 3 = 1

3x = 1

Divide each side by '3'.

x = 0.3333333333

Simplifying

x = 0.3333333333

Addison used 5/6yard of ribbon to decorate a photo frame. she used 1/3 yards of ribbon to decorate her scrapbook. which fraction
zavuch27 [327]
1/3 will become 2/6.

Steps in adding fraction.
Step 1. Make sure that the denominators are the same:
5/6 + 1/3      * 6 and 3 are the denominators. they are not the same. however, 6 is twice the number of 3. Thus, multiply 2 to the numerator and denominator of 1/3

1/3 * 2/2 = 2/6

5/6 + 2/6

Step 2. Add the numerators. Put the sum above the common denominator.

(5+2) / 6 = 7/6

Step 3. Simplify the fraction.

7/6 = 1 1/6 

Addison used 1 1/6 yards of ribbon in all.

Determine the slope of the line 3x-5y-6=0
Softa [21]

Answer:

3

Step-by-step explanation:

(-3, -3) (2, 0) are two of the points of this equation.

y2-y1/x2-x1 = slope

y2 -y1: 0 - 3= -3

x2- x1: 2 - 3= -1

-3 / -1 is the equation right now

negative divided by a negative is a positive.

now it is 3/1

3/1 is just 3
