If AC = x + 5 and AB = 3x - 1... what is the length of BC?

Hatshy [7]

If B is the midpoint of AC, then |AB| = |AC|.
|AB| = 3x + 2
|BC| = 5x - 10
Therefore we have the equation:
3x + 2 = 5x - 10 |subtract 2 from both sides
3x = 5x - 12 |subtract 5x from both sides
-2x = -12 |divide both sides by (-2)
x = 6

NAMASTE :)

0.00000000005

= 5 × ${10}^{ - 11}$

Count the Digits after decimal.
We use minus (-) in power as the digit is in left side of decimal

If they are in right side then we use (+) plus sign in power.

the cost C (in dollars) of making n watches is represented by C = 15n + 85. How many watches are made when the cost is $385?

liberstina [14]

20 watches are made since 385 = 15n + 85. 385 - 85 is 300 and 300 divides by 15 is 20.
