Title:
<h2>The year will be

.</h2>
Step-by-step explanation:
As per October 2009, the world's estimated population is 6.8 billion.
The population growth rate is 0.07 billion per year.
Hence, in x year, the population will increase 0.07x billion.
We need to find the time, after which the population will be 9.5 billion.
If we take x as the number of year that will be required, then we can represent it as
.
This is an awful question. They mean to say the number of hours practicing <em>per week</em> (we'll call it h) varies inversely with the <em>time</em> (t) she runs her event. Unless they mean to imply more practicing makes Tyler slower, in which case she should just get a pizza.
Inverse variation means the product is a constant, we'll call it k.
ht = k
When h = 1 hour t=6 minutes
(1)(6) = k
k = 6 (hour*minutes, but as long as we're consistent we don't need to sweat the unit.)
Decreasing her time by one minute means t = 6 - 1 = 5. We solve for h.
ht = k
h = k/t = 6/5 = 1.2 hours
Answer: 1.2 hours, second choice
40, because 6×4=24 and 10×4=40
Answer:
42+t
q×10 or Q(10)
x+4
1/2y
Step-by-step explanation:
there are 42 members and their combined total would be the answer
Q is the number of members now, 10 is what you need to times it by in order to get the original number of members
the sister is 4 years younger than her brother, therfor he must be 4+ older than her
half of Y would be 1/2Y
