James wants to tile his floor using tiles in the shape of a trapezoid. To make the pattern a little more interesting he has deci
Lyrx [107]

The answer is 16 inches, we can get the medians length of the trapezoid by using the formula: EF = (BC + AD) / 2.  Given: EF = the medians length; BC = top base = 12 inches; and AD = bottom base = 16 inches.

Therefore: 

EF = (12 + 16)/2 

EF = 28 / 2                                                                                                          

EF = 14 inches’ medians length is the average of the two bases of trapezoid.

Jason's business computers need servicing. The expression 81x + 108 represents a contractor's total charges in dollars for fixin
kolbaska11 [484]

Answer:

2 hours

Step-by-step explanation:

Given

Contractor: 81x + 108

Electronic\ Store: 103x + 64

Required

Determine the hours when the charges are the same

To do this, we simply equate both expressions:

Contractor = Electronic\ Store

81x + 108 = 103x + 64

Collect Like Terms

81x - 103x = 64 - 108

-22x = -44

Divide both sides by -22

x =2
