First of all not to be rude, but it is order of operations not properties of operations. Second, you can solve equations by going in the order of PEMDAS or Parentheses, Exponents, Multiplication, division, addition, and subtraction. Multiplication and division are switchable, addition and subtraction. If you do not follow this order you get the equation or inequality wrong.
Answer:
x=7/4
Step-by-step explanation:
13x-17x+7=0
-4x+7=0
-4x+7-7=0-7
-4x=-7
-4x/-4=-7/-4
x=7/4
<span>We are given the slope and the y-intercept.
m=-6/7, b=3 1/7
We use the slope-intercept form of the equation of the line to get an equation.
y = mx + b
y = -6/7x + 3 1/7
Now we need standard form.
The x- and y-terms must be on the left side, and we need integer coefficients.
y = -6/7x + 22/7
Multiply both sides by 7.
7y = -6x + 22
Add 5x to both sides.
6x + 7y = 22

Answer:
Each one of the sides is equal to 7d-5
Step-by-step explanation:
A regular pentagon has 5 sides of equal length.
The perimeter of a regular pentagon is given by
P = 5s where s is the side length
35d -25 = 5s
Divide each side by 5
(35d-25)/5 = 5s/5
7d-5 =s
Each one of the sides is equal to 7d-5
