x-5= 0
move -5 to the other side
sign changes from -5 to +5
x-5+5= 0+5
x= 5 
x-6= 0
x-6+6= 0+6
x= 6

Answer:

Step-by-step explanation:
Let
h -----> the number of hours, Elon works during one 5-day work week
we know that

Elon’s break time must be equal to 1/2 of an hour multiplied by 5 days plus  1/5 multiplied by the total hours h
so

Solve for h
Multiply by 10 both sides to remove the fraction




 
        
             
        
        
        
The answer to the first question of the attached document is option 1. We obtain the answer subtracting the term n from the series with the term n-1.For example:
 -3 - (- 5) = 2
 -1 - (- 3) = 2
  1 - (- 1) = 2
 So you can see that the common difference is the 2.
 The answer to the second question is option 3:
 y = | x + 7 |
 We can confirm it by substituting values in the equation.
 For example:
 if we do y = 0 then x = -7
 if we do x = 0 then y = 7.
 As corresponds in the graph shown.
 Remember also that as a general rule yes to the equationy = | x | whose vertex is in the point (0,0) we add a positive real number "a" of form y = | x + a | then the graph of y = | x | will move "to" units in the negative direction of x.
 The answer to the third question is option 4.
 The quotient of x and "and" is constant.
 k = y / x
 Rewriting:
 y = kx
 You can see that it corresponds to the equation of a line that passes through the origin, this means that and is proportional to x and both vary directly
