1. k (j - 3) = m
Divide the k on both sides -> j - 3 = m/k
Add the 3 on both sides -> j = (m/k) +3
2. 3 (8 - x) + 12 = 102 - 6x
Subtract the 12 on both sides -> 3 (8 - x) = 90 - 6x
Add the 6x on both sides -> 3 (8 - x) + 6x = 90
Divide both sides by 3 -> 8 - x + 6x = 30
Combine like terms -> 8 +5x = 30
Subtract 8 from both sides -> 5x = 22
Divide both sides by 5 -> x = 22/5
3. Sorry, I can't remember exactly how to do the last one.
Answer: 9 sides
Step-by-step explanation: : Since the interior angle 140 degrees, the supplement of this is the exterior angle and equal to 40 degrees. Hence the number of sides is 360/40 = 9 sides.
Answer:
35
Step-by-step explanation:
Mel has 8.
Ina has 5 less than Mel.
8-5 = 3
Ina has 3.
Sara has 4 more than Ina.
3 + 4 = 7
Sara has 7.
Jax has 9 more than Mel.
8 + 9 = 17
Jax has 17.
8 + 3 + 7 + 17 = 35
Do 180 - 83 to get the measure of LWRX. then add that answer to 31. then subtract that answer from 180 and that will be your answer
