7 times 7 is 49
49x = 4x +3
49x - 4x=3
45x=3
x=3/45. or X = 1/15
Answer:
Finally, substitute AB = 6 and BC = 18 - 2AC in
AB + AC > BC 3rd Triangle Inequality condition
6 + AC > 18 - 2AC
-12 > -3AC
4 < AC
AC > 4
So putting all three results together
AC < 12, AC < 8, and AC > 4
Since AC is less than 8, it's automatically less than 12,
so we can dispense with AC < 12. So we have:
AC < 8 and AC > 4 which can be combined and written as
4 < AC < 8 [that is, AC is between 4 and 8]
= 7/8 − 1/5
= ((7 × 5) − (1 × 8)) / (8 × 5)
= (35 - 8) / 40
= 27/40
= 27/40
SO, 27/40 minutes are NOT spend on instructions.
Hope I helped:P
