0.1x = 0.2(x + 2)
First, divide both sides by 0.1 / Your problem should look like: x = 2(x + 2)
Second, expand. / Your problem should look like: x = 2x + 4
Third, subtract 2x from both sides. / Your problem should look like: x - 2x = 4
Fourth, simplify x - 2x to -x. / Your problem should look like: -x = 4
Fifth, multiply both sides by -1. / Your problem should look like: x = -4
Answer: x = -4
Answer:
905.26
Step-by-step explanation:
905.255
We are rounding to the hundredths place, so we need to look at the thousandths place. That digit is also a 5. 5>= 5 so we need to round the 5 in the hundredths place up to a 6
905.255 rounds to 905.26
Answer:
4x + y = 1
Step-by-step explanation:
Start with the familiar format of y=mx+b, where m is the slope and b is the y-intercept (the value of y when x = 0).
With a slope of -4, we can write:
y = -4x + b
We need to find a value for b that forces the line through point (1,-3). This is done by entering this point in the equation and solving for b:
y = -4x + b
-3 = -4*(1) + b
b = 1
The equation is y = -4x + 1, This can be rewritten as:
4x + y = 1

Answer:
c. Cluster sampling
Step-by-step explanation:
Cluster sampling is a kind of sampling whereby the entire population is divided into different groups(clusters) from which simple random samples are selected from these clusters to conduct the analysis. If possible, all the individual in the selected clusters are sampled.
For the case above, Christine samples the population by dividing the residents by towns(clusters) and randomly selecting 9 of the towns(9 selected clusters). The type of sampling used is Cluster sampling. Since it involves dividing the population into clusters, and sampling the selected clusters.
