Answer:
81 million
Step-by-step explanation:
In one year there is 365 days, if you divide 365/4.5 the answer is 81.1. And every 4.5 days add 1 million people, then you multiply
81.1*1 000 000 = 81 100 000
approaching to the nearest million, 81 million of babies are added each year.
Answer:
x = 6
Step-by-step explanation:
Since, ∠1 ≅ ∠2
By angle bisector theorem,
By substituting the measures of each side in the given ratio of the sides,
12 = x(x - 4)
12 = x² - 4x
x² - 4x - 12 = 0
x² - 6x + 2x - 12 = 0
x( x - 6) + 2(x - 6) = 0
(x + 2)(x - 6) = 0
x = -2, 6
Since, measure of the sides can't be negative, x can not be negative.
Therefore, x = 6 will be the answer.
Answer:
First you start with what is in the ( ). 15- 14 is 1. then you do multiplication next. 1* 6. is 6. now you do addition. 6 + 4 = 10
Answer:
I think it is C
Step-by-step explanation:
Answer: n = -4
Step-by-step explanation:
First distribute.
2 + 8n = 6n + 6 + 3n
Then combine like terms.
2 + 8n = 9n + 6
Then move the 2 to the other side.
2 - 2 + 8n = 9n + 6 - 2
Then subtract.
8n = 9n + 4
Then move the 9n to the other side.
8n - 9n = 9n - 9n + 4
Then subtract.
-n = 4
Then make n positive by multiplying by -1.
n = -4
