Is it subtract 228? if so then 3-5 equals -2. -2-8 equals -10. -10-228 equals -238
n, n + 2, n + 4 - three consecutive even integers
3n = 2(n + 4) + 4 |use distributive property
3n = (2)(n) + (2)(4) + 4
3n = 2n + 8 + 4
3n = 2n + 12 |subtract 2n from both sides
n = 12
n + 2 = 12 + 2 = 14
n + 4 = 12 + 4 = 16
Answer: 12, 14, 16.
Answer:
Step-by-step explanation: Round to the nearest whole number. In order to find the standard deviation, we first have to calculate the mean (average) of the numbers. To get this we add all the numbers together and then divide by 12 since there are 12 numbers. The mean = 782. Next, we take each number and subtract the mean, taking the result and squaring it.
Start out by adding 50 to both sides.
2x - 50 + 50 = 150 + 50
which simplifies to
2x = 200
then divide both sides by 2
2x ÷ 2 = 200 ÷ 2
which simplifies to
x = 100
And that is your answer! Hope this helps :)
