If K is midpoint of JL then JK = 0.5JL

JL = 4x - 2; JK = 7

The equation:
0.5(4x - 2) = 7
2x - 1 = 7 |add 1 to both sides
2x = 8 |divide both sides by 2
x = 4

JL = 4(4) - 2 = 16 - 2 = 14

KL = JK = 7

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.
