The anwer to this question would be 45
24x - 1 + 20x + 5 = 180
44x +4 = 180
- 4 on both sides
44x = 176
Divide by 44
x = 4
To solve this question you would set 3x+3 and 6x-57 to equal each other, giving you 3x+3=6x-57. You would then add 57 to both sides, getting you 3x+60=6x, then you would subtract 3x from both sides, getting you 60=3x. Finally, you would divide both sides by 3, getting x=20.
Answer:
Megavolt used a Systematic sampling method.
Step-by-step explanation:
From the information given:
For every 100th evil light bulbs tested, he starts with the 42nd. This implies that;
The first bulb tested is the 142nd bulb, the second bulb tested is the 242nd...
The sequence is as follows:
142nd, 242nd, 342nd, 442nd, 542nd, 642nd .... etc
From the starting point of manufacturing the evil light bulb, the sequence is derived from sampling where each nth unit is known to be a sample, and this is only feasible in systematic sampling.
The answer to the problem you asked is x=14
