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
<u>x = 4</u>
<u>JL</u> = 4(4) - 2 = 16 - 2 = <u>14</u>
<u>KL</u> = JK =<u> 7</u>
D = 390mi
r = 60 mi/h
390/60 = 6.5
(t) = 6.5 h
Answer:
-7/15
Step-by-step explanation:
-4/5 translates to -12/15 and 1/3 translates to 5/15.
When you add -12/15+5/15 you get
-12+5/15 so you get -7/15
