Let me help you with that :)
2x - 4 = - 10 + x (we transfer the x from the right side, and transfer the - 4 from the left side)
2x - x = - 10 + 4 (we calculate this)
x = -6
And that is the answer; x = - 6 :)
Answer:
i think b
Step-by-step explanation:
9=3^2 and 10^4=(10^2)2
24) All percents are numbers with the decimal moved 2 to the right. So if you have 275%, move the decimal to the left twice to get a factor of 2.75. that means that the puppy is 2.75 times heavier at 4 months than it was at 2 months. Since you need the answer as a mixed fraction, your answer is;

28) If 6 of 75 trees are 30+ feet tall and you need to know how many are under, subtract 6 from 75 to get (75 - 6) = 69 trees under 30ft tall.
You're looking for the percent of trees under 30ft tall, so divide the number of trees <30ft by the total number of trees to get;

Move the decimal 2 to the right to get
92%.
Your answer is that
92% of trees is under 30ft.
Answer:
0.627%
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
Probability of a randomly selected household to be audited and owns a dog = P(A ∩ B) = P(A) x P(B)
where A = household tax returns audited
B = percentage of households that own dogs
0.0165 x 0.38 = 0.627%
