Answer:

<6 = 68

Step-by-step explanation:

<5 + <6 + 90 = 180  since the 3 angles form a straight line

22 + <6 + 90 =180

Combine like terms

112+ <6 = 180

Subtract 112 from each side

<6 = 180-112

<6 =68

Olivia decides to hire an electrician. The electrician charges $35 to come out to Olivia's
atroni [7]

Answer:

Step-by-step explanation:

Total cost

C (x) = 35+ 60x

Where,

Fixed cost= $35

Variable cost = 60x

x= number of hours of work

Total cost is the addition of fixed and variable cost

C (x) = 35+ 60x

C(5)= 35 + 60(5)

= 35 + 300

=335

C(5) = 335

C(5) = 335 is Olivia's total cost of hiring the electrician

x=5 is the electrician's number of hours of work

35= fixed cost of hiring the electrician

60(5) = 300 is the variable cost of hiring the electrician for 5 hours
