Same as the last one you asked. 

AB + BC = AC. Just think of it like Part + Part = Whole Thing

(2x + 6) + (6x + 5) = 51

Combine like terms:
8x + 11 = 51

Subtract 11 from both sides to get the variable and its coefficient on its own:
8x = 51 - 11
8x = 40

Divide both sides by 8 to isolate the variable:
x = 5

It's asking for us to find BC so now we plug in x = 5 to the equation it gave for BC. 

6x + 5
6(5) + 5
30 + 5
35

BC is 35 units long.

A scientist is working with 14 meters of gold wire. How long will the wire be in millimeters?
Tcecarenko [31]
In a meter there are 100 cm.
In 100 cm there are 1000 mm. 

Therefore in 1 meter you have 1000 millimeters. 

Then to find out how many millimeters you have in 14 meters, you just multiply 14 by 1000 to give you 14000 mm.

Final answer= 14 m of gold wire is the equivalent to 14000 mm of wire.
